Using Nokia LCD

[BobP]

Hi all,

I have noticed recently that LCD displays from Nokia phones (6310, etc.) are being used in PIC projects.

I have collected datasheets and before I loose more hair I wondered if anyone has written PBP code to drive this display?

Any snippets of code or hints would be appreciated.


Thanks,
Bob

A Wiki has been created for one solution for the Nokia 3310 display from a few of the posts in this thread. It can be found here: http://www.picbasic.co.uk/forum/content.php?r=174-Using-Nokia-3310-LCD.

Try here:

Is in CCS C code not picbasic pro though!

http://users.skynet.be/bk317494/

INIT_LCD:

SSPSTAT.6 = 1 'CKE
SSPCON.0 = 1 'TCK / 16
SSPCON.5 = 1 'ENABLE MSSP

HIGH CMD_DAT 'COMMAND / DATA LINE
HIGH LCD_C_S 'LCD CHIP SELECT
HIGH LCD_PWR 'LCD POWER ENABLE
LOW LCD_RST 'LCD RESET LINE
PAUSE 20
HIGH LCD_RST

LOW CMD_DAT

SSPBUF = 33 'EXTENDED COMMAND SET
PAUSE 1
SSPBUF = 200 'SETUP VOP
PAUSE 1
SSPBUF = 19 'SETUP BIAS
PAUSE 1
SSPBUF = 32 'NORMAL COMMAND SET
PAUSE 1

SSPBUF = 9 'TURN ON ALL SEGMENTS
PAUSE 100

SSPBUF = %00001100 'DISPLAY NORMAL
PAUSE 1

HIGH CMD_DAT ' GET READY TO SEND PIXEL DATA
HIGH LCD_C_S ' DESELECT LCD

RETURN

Thanks,

Thats enought to get me started. I will post the code here once I have finished it.

Thanks,
Bob.

Here's one submitted on the Proton Picbasic site.

Hi all,

I have just got my Nokia 5110 LCD working, I tried the ASM code from Berty's page (http://sandiding.tripod.com/Bertys.html), however I had problems getting it going. I re-wrote the code using PBP, now I can display stuff. It is very code intensive as the display is dumb and you have to set each pixel. I used a PIC16F628 and the Shiftout command. I will attach the .BAS file. If anybody wants to improve the code please do I would be interested in any improvements. i would also like to know how to use a lookup table to display pre defined characters.

Cheers

[Hawkesy]

Oh yeah here is a txt file for the charater set and their associated hex codes.

[bitmaniac]

Hi!
Guys
I have already smth ready for you (I think)
two months ago I tried to figure out a way to drive a nokia
LCD using just a pic and Picbasic pro!
Here is the good news: SUCCESS

As i am at work now, as soon as I find some time I will dig-out and send you the simple schematic and of course the source!
Wait till then...
See you :)
P.S As I can remember the only limit was that you need a lot of eeprom space to 'throw in' the character bitmap mask data.

[bitmaniac]

Hi,Guys!

At last I managed to dig out the infos you want.
I attached the pbp source for anyone interested
Also I have written a very good utilty in VB (included in zip)that
helps you create the graphic data you can inport in
pic basic in order to diaplsy bitmap images on the nokia lcd!

I hope you find then usefull

:))
Also included is the connection to nokia lcd

NOTE:You MUST unzip the file in your c:\matrix , in order
to run properly!

If you want a font to bit map converter have a look at the one written for PPrint.

[BobP]

Many thanks for all the replies, I have written some code but it needed tidyed up before posting. But it will now gather dust on the hard drive.

look forward to building something (even an egg timer!) just to try the code.

Thanks,
BobP

[stu746]

been trying to get this working for a while now, i am beginning to think my lcd does not work or maybe i damaged it when soldering it,

should the lcd turn black or anything when power is applied?

i used bitmaniacs code and compiled it for a 16f877a but the lcd does nothing when I power up :(

i also have a nokia 6610 lcd if anyone has a circuit and any code to get this working?

thanks for any help

Hi Bob,

the same thing happened to me this weekend !


As I can not find the 16F648 to buy here in Brazil, I´m using the 16f877 to do the tests.

I Just removed the CMCON line from the code and changed the cristal to 10 Mhz, but the display still not responding.

I have conected the Vout pin to Gnd via a 1 uf Cap.

I´m powering up the display with 5 V (maybe I should change to 3,3v)

I have seen other project powering up the display with 5V with out problems.

After some hours testin the circuit and the software with no success, I decided to test another display. But the results were the same... a blank display.

If could someone help us, it will be apreciated.

Regards !

Sérgio

[stu746]

Hi Sérgio,

seems like you are having same problem as me, did u manage to get it working yet?

i am using 5v too and am unsure wether this is the problem, but i have seen a few circuits using 5v.


Stu

[srspinho]

Hi Stu,

I'm still trying... but the display still blank, showing nothing, even a small flash when I turn on the 5 Volts.

I got two more displays, but they are 9 pin version. I will connect them using the mobile's main board 8 pin (in the PCI's Back).

Other weird behavior I'm facing is the fact of the 877, sometimes, don't start. I have to wait for some minutes and try again.
I don't have much experience in electronics, as I'm just a curious but a behavior like that is really strange.

TInight I will try the other dispplay type and if I get some good result, don't worry, I will let you know ! ! !

Regards.

ps. sorry for my bad english... portuguese is my mother language...

[stu746]

Hi again,

yeah i have problems like that with pics sometimes, i usually find it is the batteries gowing flat and need to change them.

I also have one of the 9 pin versions from a nokia 5110 I think, it seems impossible to solder to the lcd, so i tried soldering to the back of the pcb, but i could not trace one of the connections, i took a bit of a guess in the end as i think it is connected to the lcd via a capacitor.

but could not get this working any better. let me know how u get one, i am begining to think i need a better power suplpy.

Stu

[bitmaniac]

Hi Guys
Well I see that you have problems with F877 andmy code
I will try and re-try my code on an F877 to see what happens
I hope to find some time this week to try and find out what happens:))

[srspinho]

Hi People,

Alexandros, your help will be really apreciated.

Well, in the link below, there's some explanation about on how to connect the nokia display to the pc's printer port in order to show Winamp's information.
I Know that it'is not what we want but there's some explanation about the different types of Nokia's LCD (8 and 9 Pins)

http://serdisplib.sourceforge.net/ser/pcd8544.html

And for those who can read and/or undestand spanish, the link bellow show how to connect a Pic to a COLOR nokia's LCD (Epson Controller). The code is in Pic CCS.

http://www.comunicom.com.py/juno/3595/

The link bellow is the original code used by the spanish guy above and his page is in English (source code in HiTec C)

http://67.15.78.55/~spiral/colorlcd/colorlcd.html


My idea is get the monochrome working first and change the code and work with the color version.
The Nokia's LCD are getting cheap, even the color modules, and I think they could be a very good option for some projects, like meters and machine monitors as we can buy them for a good price and every cell phone service store havem them to sell. In other hand, graphical displays are not very easy and, sometimes, expansive.

My best regards to all

Sérgio Pinheiro (Brazil)

[stu746]

Woohooo!!!

got it workin at last with a 6110 lcd

it was just the contrast setting in the code!

i had tried changing it ealier, but i changed the last number only

i now have it set at d1 and works great

it now reads

SHiftOUT Lcd_SDA , Lcd_CLK , MSBFIRST, [ $21,$d1,$20 ]

i hope this is some help to others as it was driving me nuts :)

i used a 16f877a in the end and also used 4.5v, so 3.3 is not required.

Stu

[srspinho]

Hi Stu,

Nice tip !

I ´ll try this tonight.

thank you.

Sérgio Pinheiro

[stu746]

just tried with a display from a 3310 again and worked great with the contrast changed :)

[bitmaniac]

Hi! Guys
I have just finished verifying my code with 16f648 and works Fine!
I was just about to mention to check lcd initilization, contrast, etc but you have already found it by yourself so.... ALL is FINE!

I hope you have success make it work with F877
Nokia lcds is a perfect option for projects.
Also download Nokia lcd pdf it will be very useful for seting differnet parameters to lcd

I am here for any help.
:)

[srspinho]

Hi Guys,

I changed the contrast value and guess what....

It is working ! ! !

thank you Alexandros and Stu

soon I will try a color display, and if I get it working fine I will let you know here in the forum

Just one more thiing : Have you ever faced problems with Pic's in a protoboard ?

I just can not make it working. It seems to have some parasite capacitancce between the holes.
I had to move the project to a experimental PCB and make all the soldering.

Thank you again

Sérgio Pinheiro

[mister_e]

at wich frequency??? 20MHZ, on protoboard it's a common problem due to the capacitance of your protoboard. In many case, you can simply remove the capacitor around your crystal. and the problem will be fix .... on proto only.

Monitoring your crystal oscillation amplitude with/without capacitor with a scope (10X probe or bigger) will teach you more.

Also you must add 0.1uF and 10uF tantalum, close to your PIC.

[srspinho]

Hi Steve,

thank you for your advice.

I`ve moved my circuit from the ProtoBoard to a PCB (universal one, with isolated holes), reduced the crystal speed to 10 Mhz and now, everything is soldered.
Just the power supply lines are a bit long (I´m using a regulated 5 V Power supply).

I still have problems to make the 16F877-20 and the 16F877A working. I have to touch the PIC with my fingers many, many times to make it working ! ! ! really strange...

I tried to substitute the crystal for a ressonator too... but I got the same problem...

Is there another option rahter than the Tantalum Caps ?

Is this problem related to the Power supply or to the Crystal Speed ? (maybe both ?)

Thanks

Hi, just noticed this, I had many problems all over the place to do with touching the pic to make it work, with serial comms, LCD etc etc.

It turned out that i did not connect MCLRE. it was floating. so it never worked untill my static charge from my fingers pulled the pin high. Also check that other main pins arnt floating. (by main i mean not output/input pins.)

capacitors from +V to Ground near the pic also help. They basically filter out noise from the powerline/regulator. 100nf usually do the trick

Hi Phil,

thank you for your tips.

I will try them tonight

Hi everyone !

after some good results working with the nokia LCD, I decided to wite a routine in order to draw an small histogram in the Nokia´s LCD.
But, after reading the PCD8544´s datasheet, i discovered that the LCD doesn´t have a direct mode wich allow us to draw on it pixel by pixel, and when we need to set a single pixel, we need to know its other 7 neighbour pixels.
Is taht right ?

Do I need to read the memory first and make some logical operation with the bits to draw what I want ?

Have someone developped a routine to draw lines (for example) on this LCD ?

thank tou

[Tim B]

PCD8544 will not let you read the screen so the best you will ever be able to do is keep a copy of the screen in the PIC's ram and then dump the whole screen to it at once. The data rate to these devices is slow though so you will not want to do it often.

Hello,
I am trying to interface the Nokia 3310 LCD to a PIC16F876A.

Im using bitmaniacs schematic/code
Im running on a 16Mhz crystal.

I tried everything possible mentioned in the last posts
change the contrast from $a7 to $d1

Theres no response on the LCD..doesnt even turn dark..

Is there anything im missing out.
Thank you

[NavMicroSystems]

ice,

attached is a working piece of code to play with.
(Tested on a 16F877A)

[ice]

Thank you Nav,
but it still shows no response..i tried it with 2 displays with the circuit as in bitmaniac's

are there any other values ,other than $d1 which i can use to adjust contrast?

Ive tried changing sll the other parameters like bias,temperature coeff..

Regards,

[NavMicroSystems]

ice,

the code example is tested and working.

There must be something wrong in your Hardware.

could you post your schematic?

[ice]

Nav..
It's the same schema as bitmaniac had given..(18th sep 2004)

I redid the connections according to the program u gave..

the schematic is attached

Thanks!

Hello friends, excuseme for my english, it's not my language...

It's so interesting to drive nokia LCD's, but i have questions:

1) The nokia LCD has an internal controller, or are you controlling directly the crystal display???
2) If in the fact it have a controller, where can i find information about how to drive my LCD. I have LCDs of nokia 8260, nokia 5120, nokia 6120... there are TDMA cell phones and I don't know what type of LCD they have.

Help me please

Thanks

ice,

please doublecheck your hardware setup.

I have only a small 100nF cap on Pin 7 (VOUT)
and Pin 5 (SCE) is directly tied to GND.

[NavMicroSystems]

...where can i find information about how to drive my LCD.
Help me please


All Information you need can be found on this thread.
Check the links and attachment posted here.

[ice]

Nav,
I got ur code to work on a 873A.. i can move the cursor position to any place on the screen ..however,the digits which have to be displaying are all boxed..but i can notice the numbers changing...also the display keeps flickering..
I tried changing the init value in ur code too...but i cant seem to find the optimal ones..

Thanks alot

[NavMicroSystems]

ice,

to be honest, the code is not mine,
it's is more a combination if things I have cut and pasted
for testing purposes.

I'll have a deeper look into it when I find time.

BTW.
I'm running the LCD @ 3.3V!

Thanks so much for your help, but I need more help...

I'm talking about the specific models of LCDs that you can found in nokia TDMA cell phones: Nokia 8260,Nokia 5120, Nokia 3320...

I seen the photos of the projects and i can see some diferences with my own LCDs, so my question is if your LCDs have an integrated controller or are you driving directly the crystal display, without an LCD's internal controller that can have communication with the external PIC micro?

Thanks again...

[NavMicroSystems]

ok, here are some links:

http://serdisplib.sourceforge.net/ser/pcd8544.html
http://sandiding.tripod.com/lcd.html
http://67.15.78.55/~spiral/colorlcd/colorlcd.html
http://nokiaport.de/pinouts/pinouts.htm

most of the monochrome NOKIA LCDs have an embedded PCD8544 controller (PHILIPS)

If you google for NOKIA LCD you'll find many more.

[NavMicroSystems]

and here is yet another working piece of code.

dependend on your LCD
you will have to adjust the values in the LCD_Init Routine

[crematory]

Hello

I need a complete PICBasic Pro code for controlling Nokia 3310 LCDs, as I have plenty of those, can any one post it here please, also I need this LCD datasheets.

Thanks in advance

Crematory,

Pleas read this thread from the beginning.
There are several code examples and linlt to DataSheets etc.

Hi all

any body deal with Nokia 6310 LCD ?
it is exist two opinion about this LCD :
first it is operate by i2c protocol .
the other operate by SPI 3-wire .
which is true ?

Have you 3310 lcd library for isis ?

Hi PCBB

As there has been a lot of time since last worked in this project (matrix proggy of mine e.t.c) I have to re-scan my nokialcd files to answer you...
Please wait a little and I 'll see what I can do for you.

[pcbb]

i wait your message back. Thanks for interest.

[pcbb]

Which program did you use for convert to hex ? there are many program for graphic lcd but they dont make 5 columns about data, more! So Microcode program give error "Address exceeds maximum range for this processor " My processor is 16F877

There are many converter in this site, h**p://www.compsys1.com/workbench/Benchware/GLiPIC2/glipic_2.html
Can you help me for this problem ?

[bitmaniac]

I didn't manage yet to visit my lab (upstairs) to compile and try my code for you !
I hope this weekend :)

[shahidali55]

hello bitmaniac,
In some previous posts, it is said that your code contains some errors. Can you point out those errors to me ? ? ?
I'm having a hard time getting the nokia 3310 LCD to work.

[shahidali55]

bitmaniac,
Where do i have to place the data generated by the matrix program ???

[Russian]

shahidali55, you have to place the data in the start of your program, after the device and xtal definition. However, I stumbled on a problem with bitmaniacs matrix program. It generates code in one long string for ech line of the display, however these lines get to long for the PICBASIC to interpret them, so it cuts them off when they are longer than 250 symbols, so the picture gets ruined. I tried to write my own program, that would split the data in more lines, but when i split the data it for some reason ads a $00 byte after each line which results in shifted lines, that also ruins the graphic. Does anyone know how to deal with this?

Any replies would be appreciated
Regards
Denis Tcherniak

Well, since we can't see the program that you wrote and the problem that it entails, I can only speculate the problem is that you haven't changed the oil in your automobile or rotated the air in your tires yet this year.
Post some code!

[Russian]

I meant, that's not a bug in my program, it works perfectly, i mean the PICBASIC program. When I add multiple DATA statements eg.

DATA $FF,$FF,$FF,$FF,$FF,$FF,$FF,$FF,$FF,$FF,$FF
DATA $FF,$FF,$FF,$FF,$FF,$FF,$FF,$FF,$FF,$FF,$FF

and then make the pic "paste" all the data to the screen it adds an empty column after each DATA line. It draws the first 11 black lines then it adds an empty line, and then it continues to the second data line.

I don't follow what you're trying to say...pic 'paste'...adds empty column...???
If it's not a bug in your program (what program? where?) and it's a PICBASIC problem, then post the code for the PICBASIC program. I've used DATA plenty of times without a problem, up to and including lines 254 characters long.

[Russian]

By, "my program" i meant a prog I wrote in VB.net for converting BMP pictures to PBP DATA code, so the lines wouldn,t get longer than 250 characters.

I am sorry, it is late, and it is hard to explain the problem. I have attached my PBP code. The data I want to use as picture is declared in the very start of the program, and it is slitted, so the lines are < 250. After the initialization of the display I call the LCD_SHOWIMAGE sub, this happens at line 95. The LCD_SHOWLCD is running a loop 504 times, each time advancing to the next DATA byte, to fill the entire display matrix with data. I am using a filled with black pixels image to make the debugging easier. I have attached a photo of the display, when my program has been run. The focusing isn't good, but notice the white lines. There are 8 of them, equal to the number DATA strings in the program.

Ioannis,
could you please help me out with the variable names?
Can you give me the meaning of variable names like Bitovi,Predznak,Skala,MinusNaSkali,PrintSkala ?
I am having a hard time understanding what these variables mean...

[Ioannis]

I don't speak that lanquage too, but I think the meaning is as this:

Skala = scale
predznak = flag
MinusNaSkali = Negative Scale
PrintSkala = Print Scales on LCD

Hope it helps you a little.

Ioannis

[shahidali55]

I think predznak = sign
What does "Bitovi" represent ???

[mister_e]

Assuming it 'could be' Croatian, i think it mean 'Bit' or 'Digit'

well...
http://www.eudict.com/?lang=croeng&word=bitovi&submit=Search

[Ioannis]

Well, after looking the program again, bitovi is defined as byte to store a flag. That flag is 'predznak' which as you stated could be the sign.

The bitovi is not directly used anywhere in the program.

Ioannis

[Emil G]

Predznak = prefix like - or +
Bitovi are bits (flags)

Hi bitmaniac & all,

I used bitmaniac's matrix.zip files to wake up my LCD with 16F876A and wake up was success :)

Then I tried to add some new characters to EEPROM area (DATA), but EEPROM is quite limited. I made some modifications to (Lcd_SentChar, attachement) and removed all character from EEPROM area. Now I have both A-Z and a-z characters available, working fine :)

Also I added some extended ASCII codes, like Ä,Ö,ä,ö but then I noticed problems? It seems that LOOKUP cannot handle extended ASCII codes? Error message was: Argument out of range. Least signficant bits used and there was no exteded ASCII on LCD

LOOKUP2 didn't give any errors, but no extended ASCII characters on LCD.

Can somebody help, how to show extended ASCII with LOOKUP command?

I know it's not very new, but I think is interesting.
This program receive text information true rs232, display in a Nokia 3310 LCD capital and small letters, display 3 sizes off characters, variable and fixes size of characters, normal and inverted screen and character.

I've test the program connecting the Tx of my Pc tru a 74ls04 and it works greatly with 3.3 v

Have a nice time!

What's wrong with the code?
1 - It'll never compile in PicBasicPro. Not today, not tomorrow, not ever.
2 - It (the .bas, the includes, everything about it) it written for a 12F, not for the 16F series.
3 - You're in the wrong place. Most likely www.picbasic.org is what you really want. Since this (http://www.picbasic.org/forum/showthread.php?t=8603&highlight=nokia+3310) is where you got the code in the first place.

I don't know how many is still using old (monochrome) Nokia LCD displays, but I do.

To make it easier to write code for both 3310 LCD (PDC8544) or variants (Nokia 8210...) and 7110 LCD (SED1565), I made a common command library for both LCD types. So you can use same commands in your program and only change display and link right library file (see attachement for more info). Of cource there are more pixels in 7110 and therefore you must do some fine tuning for character/picture positions, but anyway it will work with a minimum effort. At least I hope so.

I use this by including it to main program

'----- LCD Setup -----
include "LCD_3310.pbp"
or

'----- LCD Setup -----
include "LCD_7110.pbp"

Most of the code is already posted here earlier (BIG thanks for that!), something is modified and something new.

[douglas.mauro]

Just what I was looking for, thanks!

Questions:

(1) How do you recommend writing entire words "Hello World...". Do we really have to loop through every letter? Would be nice to issue a Lcd_Send_This("Hello World")

(2) Do you use a large LOOKUP table or CASE for A-Z ??

Right now I have a LOOKDOWN table for A-Z that gets the position and then uses that num*6 to LOOKUP the bits in my huge table (no eeprom here).

(thoughts) Looking ahead I worry about not being able to use a VAR in LOOKUP. In the end, isn't that what I really want to display?

Thanks again.

[Gusse]

(1) How do you recommend writing entire words "Hello World...". Do we really have to loop through every letter? Would be nice to issue a Lcd_Send_This("Hello World")

Check page 22 from Philips PCD8544 datasheet (http://www.nxp.com/acrobat/datasheets/PCD8544_1.pdf). It shows how characters are formed to LCD. If you are using 8x6 pixel fonts then you have to do 6 write operations (each of 6 column separately). This can be combined to one loop, so it writes one character or graphics at the same time. Yes, You have to loop through every letter.

Thanks again.
LOOKUP table or CASE are good options, even IF - THEN can be used. I have tried all of them, now using LOOKUP2. If you don't need all alphabets then some limited table or direct data to LCD can be an option. With direct data I mean that you make characters like a graphics, turning on/off DB7:0 data bits.
In case you need A-Z and a-z then LOOKUP or CASE needs twice more space. Then external EEPROM becomes very handy.

Try to clear the LCD, that should help. See my post (#95) couple of replies above for more info about LCD commands.

Do you want to measure temperature more than once? At least there is no loop back to Main. Also I have noticed that DS18B20 gives 85 degrees for some time at the first start (when powered). This might be the reason why you see 85 and some some dots on your screen.

Could you post your entire code here? At least I did not see where you write "TEMP:" to screen. Also at which point you do your LCD clear routine. Problem might be in that code area...

Sorry...mea culpa ! This is the full code !

You are not using "LCD_Clear:" routine anywhere, so you are not clearing the LCD at any phase.

Add this before "Main:"

call LCD_Clear

If that doesn't help, try to replace manual LCD write commands with SHIFTOUT. Similar what you have in "LCD_ByteOut:"

Can somebody explain to me, please ?

You want to have "Temp:" on Row0 and temperature reading on Row1? If this is the case then I recommend to use library from post #95.
This is how you can move positions on screen.

PosX=[X-axis pos]:PosY=[Y-axis pos]:Gosub Lcd_GotoXY


1) Goto PosX=0 and Pos=0

PosX=0:PosY=0:Gosub Lcd_GotoXYThen add LCD write routines to display "Temp:"

2) calculate where you want to write on Row1.
X-axis
84 pixel, 6 pixel width per character = 16 character per line
Temp: -> 5 character -> 5 * 6 pixel = 30 (start pixel for temp reading)
PosX=30
Y-axis
48 pixel, 8 height per character = 6 character per column
1st row = 0, 2nd = 1, ... 6th = 5
PosY=1

PosX=30:PosY=1:Gosub Lcd_GotoXY
Then add LCD write routines to display temperature reading.


To take library into use, insert this to your code and save & unzip-file Nokia_LCD_3310_7110.zip to same directory (or mod path).

'----- LCD Setup -----
include "LCD_3310.pbp"

You might want to use also other library functions... it might easier your life...

TRISA= % 10100010
In the schematic I see : RB6,RB7 not used - why "1" ?
RA7 not used - why "1" ?


Can someone explain me ? Thanks in advance !

[Ioannis]

May be he used it for some tasks and forgot to make it Output (0).

So if you do not intent to use them, make it output. If you still want to keep it Input suggest to tie pull up or pull down resistors. Do not let any pin float.

Here is an include file that has been modified from many peoples code in this thread, and Darrel's PrintStr function, for the nokia-3310. It allows for very simple printing to the LCD.

You can also print different things on the same line, by using the x, and y, positions.

example:


DEFINE OSC 48

include "modedefs.bas"
include "LCD_3310.pbp"
start:

@ PrintStr 0,0, "I love being"
@ PrintStr 0,1, "able to print "
@ PrintStr 0,2, "so easily!"

[Gusse]

Very nice! Now printing to Nokia LCD is definitely easier. :D
Thank You and Darrel!

[fratello]

Hi again !
Based on the schematic from post #119 I wrote the code from the thermostat ; but nothing happening when I push button on pin 7, or 8, or 9. I know that something is wrong, but I need help...Thanks in advance for every reply !

[ScaleRobotics]

Hello fratello,

Can you tell us if there are any parts that do work? It is always easier to trouble shoot if you know where to start.

Like:
Can it blink an LED, or are we unsure if it is even starting up?
Does it print to the LCD, and just not give you the temperature, or is the LCD blank?

[fratello]

Thanks for reply !
The display show like in picture from post #116. But pushing the buttons '+' , '-' or 'Mode' has no effect.

[ScaleRobotics]

Hello Fratello,

I have been looking over your code for a while now. I have not found anything obvious to me, although there may be something obvious to others.

One thing I did notice, is that your MainLoop will cycle through modes 0, 1, and 2, even without any buttons being pressed. This is fine, but one thing you are doing in mode 2, and after mode 2, is writing to the eeprom. At 4 mhz, you will reach that 1,000,000 write cycles quicker than you think (have not calculated it, but if this is really going to be a thermostat, I assume it is going to be running for a while). A better way to do it would be to only write the targettemp, etc to the eeprom when targettemp is different than the eeprom value for targettemp (ie, it has been adjusted).

Seems like the next step is to see if the 16f628a even knows if the buttons have been pressed. Why not make a simple light an LED line inside some of your if then statements to verify the chip knows a button has been pressed? This could help point to the source of the problem.

The code works PERFECT with LCD 2x16...I just try to insert the parts for Nokia display...(and removing, of course, the parts for other display). I think the problems are generated by wrong 'substitution'. Thanks anyway for reply !

[ScaleRobotics]

That's great! If it is working perfectly with the 2 x 16 lcd, you should be seeing the new changed values in your eeprom. This should be an indication that only your LCD_3310 code is bad, and that the thermostat functions are working!

[Archangel]

Hi fratello, Do you have pullup resistors on those switches ? You do not have WPU enabled, so you need them, or change the Option_Reg, to enable them.

[fratello]

Me again !
I found the mistake ; after MainLoop the code must be :
If PortB.3=0 then ; this is the missing line
If PortB.3=0 then MainLoop
...
...
Endif
Endif

Work correct on pushing MODE button , but...
Now I have another problem... I attach the code for display the temperature in both cases (LCD 2X16 ; N3310).
How do I convert this line :
LcdOut $FE, $C0, "OUT ", Sign, DEC (Temperature2 / 100), ".", DEC2 Temperature2, " ",223,"C "
for correct results on Nokia display ?
DEC (Temperature2 /100) it's what char ?
DEC2 Temperature2 it's what char ?
I try many codes but on display appears numbers and strange characters....
Thanks !

[ScaleRobotics]

How do I convert this line :
LcdOut $FE, $C0, "OUT ", Sign, DEC (Temperature2 / 100), ".", DEC2 Temperature2, " ",223,"C "
for correct results on Nokia display ?
DEC (Temperature2 /100) it's what char ?
DEC2 Temperature2 it's what char ?


Here I am assuming that at 25.1 degrees c , Temperature2 = 2510
On yours, it looks like it would be:


char = (Temperature2 dig 3) + 2 'get digit 3 ("2"510) and add 2 so it matches eeprom
move x y to right location and print it 'do whatever you do to print to lcd
char = (Temperature2 dig 2) + 2 'get digit 2 (2"5"10) and add 2
move x y to right location and print it
char = 14 'in you eeprom this is a "."
move x y to right location and print it
char = (Temperature2 dig 1) + 2 'get digit 1 (25"1"0) and add 2
move x y to right location and print it


But I thought from your picture in post #116 that you were printing temperature already?
http://www.picbasic.co.uk/forum/attachment.php?attachmentid=3335&stc=1&thumb=1&d=1239970805
Now I am confused again...

I now see that your change to MainLoop fixes the write to eeprom every cycle problem too. Very nice.

[fratello]

THANK YOU ! And THANK YOU ALL !
It's work ! Yes !!!!!! I'm -once again, thanks to you, all- happy !
This is the 1.0 version of code for dual zone & thermostat with Nokia 3310 display ! All the best to all !

[fratello]

Version 2. Some minors but necessary modifications. Tested - function of thermostat work fine. Not tested for negative temperatures...

[fratello]

Tested with negative temperatures; bug fixed !
I can't - insuficient memory ! - using design like in post #116 (borders & author name). How to free memory ? I think the code can be optimized...

Easiest way . . . Use 16f648A, then you have room to stretch your legs.

[ScaleRobotics]

Agreed, to upgrade to bigger chip is probably the best way.
If you just need to try a little more room, you could try taking out your graphics:

Ok, the printing a variable solution:


PosX = 0 'position 0 of 84 in the x direction
PosY = 0 'row 0 (of 0-5)
gosub Lcd_GotoXY
Lcd_Data = (result dig 3) + 48
gosub Lcd_SendChar

PosX = 6 'position 6 of 84 in the x direction
PosY = 0 'row 0 (of 0-5)
gosub Lcd_GotoXY
Lcd_Data = (result dig 2)+ 48
gosub Lcd_SendChar

PosX = 12 'position 12 of 84 in the x direction
PosY = 0 'row 0 (of 0-5)
gosub Lcd_GotoXY
Lcd_Data = (result dig 1) + 48
gosub Lcd_SendChar

PosX = 18 'position 18 of 84 in the x direction
PosY = 0 'row 0 (of 0-5)
gosub Lcd_GotoXY
Lcd_Data = (result dig 0) + 48
gosub Lcd_SendChar


got a little old. So I managed to write my first macro. It lets you do the above with a two liner:



VarData = 12345 'load the variable with desired number
@ PrintVar 0,0 'print the variable VarData, starting at the desired location 0,0


The code does the rest, and moves to the next position to print the next digit, until done.
I also edited the PrintStr function to scroll to the next line when it runs past the end of the current line.



@ PrintStr 0,0, "If I write more than one line, it will scroll to the next one, and next."


It runs on an 18f67j50. Not sure if it would run on a 16f or not.

Hi Fratello,
I tried to compile the file you put here. It did not give any error to me like what you said. The resultant files are appended in the zip file for ready reference.

[fratello]

The code is full functionaly ! The graphics it's disable... If try to improve the way that "look" the display, it is no more space in memory...I think the solution it's to 'up-grade' to another PIC, with bigger memory !

[ScaleRobotics]

I found out how to add variables to my macro, so now using the include file, you can print any variable to the lcd by using:

@ PrintVar x,y, _anyvariablehere

(instead of loading a specific variable , then using @ PrintVar that I had before). Small change, but I figured it might help someone.

Here is the segment of the macro that is part of the lcd_3310v31 include file (attached).


'@ PrintVar macro function
'format should look like this: @ PrintVar x,y, _anyvariable
ASM
PrintVar macro x, y, Variable ;input values from: @PrintVar 0,1, _any_variable
local OverVar
goto OverVar
OverVar
MOVE?CB x, _PosX ;move x from above statement to PosX
MOVE?CB y, _PosY ;move y from above statement to PosY
MOVE?WW Variable, _VarData ;move variable in statement to VarData
L?CALL _VariableOut ;call VariableOut function
endm
ENDASM

VariableOut:
@ bcf _digits
for n = 4 to 0 step -1 'cycles through all possible digts of number
Gosub Lcd_GotoXY 'place character at position PosX and PosY
Lcd_Data = (VarData dig n) + 48 'digit number n to character str format
if Lcd_data = 48 and digits = 0 then SkipChar 'skip if first char is 0
@ bsf _digits ;show that one character has been printed
gosub Lcd_SendChar 'print char to screen
PosX = PosX + 6 'next x position for character
SkipChar:
next n
return

I feel if one could write straight in assembly language, it would be smaller, in size. my comments may not suite the site s it is meant for promoting BASICHi Sarma,
Certainly well written assembly code should use less space than assembly generated by a high level compiler, it all boils down to cost. If you live where the cost of living is very low and software engineers are paid little, assembly may be the correct path. If you live where everything costs way too much and software engineers start out at $50,000 and go way up from there, it becomes very difficult to recover that cost by saving $0.15 on the wholesale cost of the PIC. One other consideration in both instances, if the engineer uses the high level compiler, the time saved will be used to engineer more products. So IMHO, the way to achieve best overall results is High Level compiler WITH assembly assists, I E . . . Darrels Instant interrupts for example. As for your comments . . . Your comments are welcome here. We all benefit by sharing our Ideas and opinions, and we can keep them after sharing or adopt new ones, I believe it was Albert Einstein who said, " all knowledge is trial and error", which is to say the things you are taught are the result of somebody's mistakes.

Hi to all !
Me again...with one new problem : I write the code attached, for 16F648A, because I want to display some graphics elements (see sus, rand 1, rand 2, rand 3, rand 4, jos) .But when I put the code in Microcode Studio I receive the message "Warn : Test_648.asm 790:[102] code crosses boundary @ 800h". I think the code it's too big; please give me some solution !!! I want that my display having one nice 'looking' and without the parts for graphics elements...What can I do ?
Thanks in advance !

[ScaleRobotics]

That is just a warning that you are crossing a boundary. All is good. How many bytes does it say you are using the lower left of microcode studio?

[fratello]

This is what MicroCode Studio say :

[Gusse]

This is what MicroCode Studio say :
Your code compiles OK (2932 words used). I don't understand what can be wrong with your setup? If you close and restart the MicroCode Studio, would that help? At least sometime that has helped me.

To get rid of "code crosses boundary" goto tool bar:

View -> Editor Options...
In General sheet, select "Disable 'code crosses boundary' ASM warning.

The first one is about your config fuse. intrc_osc should be replaced by

INTRC_OSC_NOCLKOUT
This one use the same config fuses as 16F628A & 16F627A. The complete list is in M16F62XA.inc file in pbp\inc folder.

The second one is just a warning,
http://picbasic.co.uk/forum/showthread.php?t=555&

Can be bypass within MicroCode Studio.

[Ioannis]

Code is OK. May be you need a restart.

Steve, the define is OK. It exists this too!

Ioannis

[fratello]

OK ! Thanks ! I just wait for the 16F648A...

[fratello]

I have the 648A. The code works just fine !
...but : I try to define anothers characters for display the temperature that I set ; the message is like in picture. How can I define anothers characters ?
Thanks in advance !

[ScaleRobotics]

I found that I could add up to 6 more characters (30 more bytes) to your code without getting the same error. I don't know exactly why you are getting the stack overflow errors, but the eeprom space is very limited. Since you have so much more space with the 648a, you might think about storing all the character data in program memory. You would need to modify your code a little bit though. You can edit out the characters that you don't need to save a little space.

Ok, for some reason it works if you say DATA @10,some data here, then when you have gotten about half way through the eeprom, stop writting, then start writing again where you left off with DATA 128(or where ever you left off at),rest of your data here.

Don't know why you can't do it like you originally tried, but PBP does not seem to like it.

[fratello]

Thanks for repply ! I will try both variants.

Hello ! Me again... Using PIC 16F628 (or A) with 4 MHz X-tal, one DS18B20 on port RA1, push-button for setting Hours on RB3 and for setting Minutes on RB2, I wrote the code for this thermo_clock. Works verry fine ! All the best !

Based on code that I post at #155, it is possible to use BIG fonts like in this example : http://users.picbasic.org/Howto/PPRINT/PROTON+%20Pprint%20update.pdf ? Of course, just display the temperature, with big font, without others graphical elements... The commands are in Proton+ ,but it's possible to use with PBP ? What are You thinking ? Thanks in advance for every repply !

[ScaleRobotics]

It looks possible. You would have to create custom characters for the 3310. Some helper bitmap font editors are available, like http://www.crystalfontz.com/forum/showthread.php?t=3619 to help you write the code for each character. How big are you wanting to go?. The link I showed goes to 10 x 14. But a font like this 10x14 (just look at fonts on this link) is bolder http://www.ageta.hu/pdf/gw64x16C-K610a-03.pdf. But perhaps you want even larger?

[fratello]

Please take a look at this ideea :
-in picture I figure how increase the size of characters ;
-in the code I try to explain how I see the problem.

You might try something like this. The characters you show as an example could be simplified to fit into half the space, but this allows you to smooth the characters if you like. I did not smooth them, just kept to your example font, so hopefully you can see what I am trying to do. Each hex data point of the character is basically a binary image of the column. It starts at the base of the character, but since our character is going to take 4 character positions, our zero starts at half of the 16 pixels high. So the left column of the top of the zero is 11111100 (or $FC) all the 1's are black. As you can see, it takes a long time to make the characters. There may be a tool out there somewhere to make this easier for you. Hopefully you just need numbers!

The building of the characters are shown on the data sheet for the display on pages 8-9, and 22-23.

The attached program fastLCD.zip will help you with text, as well as graphics. It will let you create characters, and it will create hex for them.

http://www.picbasic.co.uk/forum/attachment.php?attachmentid=4159&stc=1&d=1270623366

[fratello]

Nice program, but I use already Excel (bin2hex) for those big characters...Unfortunately, I need to understand the codes You and HJota propose and modify all my code; the procedures for define and display the characters are different...Per aspera ad astra :) ...

[fratello]

I succeded to display "23.56" ! it's a step, don't ?!
Now, assuming that I succed to write the code for reading DS18B20, how display temperature instead "23.56" ?
It's correct so : " lookup i, [temperature DIG 3, temperature DIG 2, temperature DIG 1], j" or how ? Thanks !

[ScaleRobotics]

How about changing from this:


for i=0 to 4
lookup i,["23.56"],j
lcdstr(i)=j
next i


to something like this:


lcdstr(4) = 48 + temperature dig 3
lcdstr(3) = 48 + temperature dig 2
lcdstr(2) = "."
lcdstr(1) = 48 + temperature dig 1
lcdstr(0) = 48 + temperature dig 0


You would have to do something when your temperature goes to single digits though.

[fratello]

What I put here ?

lcdstr(4) = 48 + temperature dig 3
lcdstr(3) = 48 + temperature dig 2
lcdstr(2) = "."
lcdstr(1) = 48 + temperature dig 1
lcdstr(0) = 48 + temperature dig 0

Tc=2
for i=0 to 4
lookup i,["??????"],j
lcdstr(i)=j
next i
nC=5

[ScaleRobotics]

What I put here ?

lcdstr(4) = 48 + temperature dig 3
lcdstr(3) = 48 + temperature dig 2
lcdstr(2) = "."
lcdstr(1) = 48 + temperature dig 1
lcdstr(0) = 48 + temperature dig 0

Tc=2
for i=0 to 4
lookup i,["??????"],j
lcdstr(i)=j
next i
nC=5

remove the for i = loop. The code above will load the values in the lcdstr string.

[fratello]

like in picture attached. The code works great, with one DS18B20; next project is, of course :), termo with two zone, with thermostat, with clock, etc.,....

Because this topic it's still "hot" I wonder if somebody have meeting this problem : I bought some Nokia 3310 displays and bottom of display appears these stranges characters...using same code and hardware (see post #169). The results on display are like in picture (original vs fake; both display look hardware just the same). Suggestions ?! Thanks !

[ScaleRobotics]

Not sure if this will help, but I did notice a difference in the way we initialize the display.

Try adding some time, and another pause after, and see if that helps.


Low Lcd_RST
pause 50
High Lcd_RST
pause 50


Otherwise, my only advice would be to try to get from same manufacturer. One display seems to have the part number info on it, the other does not. Is the one with the part info printed on it the working one?

[fratello]

Even with "pause 100" don't work ; still "fleas". And yes, the display with part info printed work good. The last line it's with problem !!!! She don't want to be erased !! I try another program and look at differences. First two foto are with good display; "main" program - and, after LCD_clear , "set" display. The last two are with "fake" display. The last line remain from "main" program display !!!

LCD seems to work OK if you can write text to it, to all 6 rows. Try some PAUSE after Lcd_Clear -command if that will make any difference. Could it be so that LCD controller is quite slow and next command will override Lcd_Clear. Just speculations ...

BR,

[fratello]

Thanks for repply ! But...with "Pause" (10-200 !) it's worst !

[Gusse]

Are you using similar LCD_Clear code as in post #161 (http://www.picbasic.co.uk/forum/showpost.php?p=87839&postcount=161)?

Would code below make any difference?
At least it has worked for me very well with several different 3310 LCD modules.

Here : http://www.edaboard.com/ftopic324477.html&usg , I find something interesting...

[Gusse]

So, somebody is selling fake 3310 LCD displays, that are actually with 102*80 controllers. Nice practical joke!
I bet that those aren't made by Philips, Samsung or Seiko Epson. :rolleyes:

Hi Fratello,

Try this one. It will change row after it has cleared 84 pixels. Old version changed row also after 84, but if you have 102 pixels per row then 502 positions are not enough.


<code><font color="#000000">Lcd_Data <b>VAR BYTE
</b>Cursor <b>VAR BYTE

</b>Lcd_Clear:
<b>FOR </b>Cursor = 0 <b>TO </b>5
PosX=0:PosY=Cursor:<b>GOSUB </b>Lcd_GotoXY
<b>HIGH </b>Lcd_DC
Lcd_Data = 0
<b>FOR </b>Char = 1 <b>TO </b>84
<b>GOSUB </b>LCD_ByteOut
<b>NEXT </b>Char
<b>NEXT </b>Cursor
<b>RETURN

</b></code>

or


<code><font color="#000000">Lcd_Data <b>VAR BYTE </b>[6]

Lcd_Clear:
PosX=0:PosY=0:<b>GOSUB </b>Lcd_GotoXY
<b>HIGH </b>Lcd_DC
Lcd_Data(0)=0:Lcd_Data(1)=0:Lcd_Data(2)=0:Lcd_Data (3)=0:Lcd_Data(4)=0:Lcd_Data(5)=0

Thank's ! Of course, You are right ! So simple solution...Great !

Lcd_Clear:

Hello tahirmaqsood,

Your schematic seems to be advertising used cars. I am not sure how any code I could come up would be related to used cars, so I can't really help with the code for the sensors.

But here is some code for talking to the LCD display:
http://www.picbasic.co.uk/forum/showthread.php?t=327&p=73728#post73728

Please do not cross post copies of the same question to other threads.

By the way, are you still using Proton, or have you switched to PicBasicPro?

[ScaleRobotics]

The Nokia 3310 display just became available at Sparkfun for $2.95 each. Pretty good price for what it can do! You can check it out here http://www.sparkfun.com/commerce/product_info.php?products_id=9924. Here is the wiki page about interfacing it, based on posts in this thread: http://www.picbasic.co.uk/forum/content.php?r=174-Using-Nokia-3310-LCD

[wjsmarine]

Hi Walter,

Great job on your macro for the Nokia 3310 LCD, so much so that I think I'll move across to using these instead of the 16x2 I've been using everywhere so far. Thank you.

I'm not having much luck getting the @ PrintVar x,y, _anyvariable to work though. I declare a word variable in my main program (j var word), give it a value to test (j=12345) then
@ PrintVar 0,4, _j
but only random values print and only 2 or 3 characters. Weird.

Can you perhaps show me a working section of how to do it please? I'm using PbP 2.60, 18F252.

Thanks and regards,
Bill

[ScaleRobotics]

Thanks Bill.

I double checked the code I posted here: http://www.picbasic.co.uk/forum/content.php?r=174-Using-Nokia-3310-LCD, and it is working for me. I am using this hardware: http://www.picbasic.co.uk/forum/showthread.php?t=10820 running at 48mhz.

You are using the right syntax, so I can't really find the problem.

The PrintVar is how I am printing the word variables in this example: http://www.picbasic.co.uk/forum/content.php?r=210-Angle-determine-tilt-from-3-axis-g-sensor

You want to post your code, and I will see if if runs on my hardware? I don't have an easy way to change my hardware for the display.

[wjsmarine]

Hi Walter,

Attached code for the 18F252 also an edited copy of your Include file - only a few small font changes but it's what I'm using so here it is.

I tried using Variable in place of j but same result. I'm sure it is something simple but I can't see it...

Thanks for your help,
Bill

[ScaleRobotics]

Hi Bill,

After looking at it and testing for a while, there was an error in most of my early includes files. I learned about the jumpover a little late. I compensated for this in my example programs, but it made it harder for others to use.

For instance, in your LCD_3310v32.inc file, please change goto Start to goto OverLCD

and at the very bottom of this include file, add this line: OverLCD:

This fixed your code for me.

Edit: and you should have _j or any other variable, but not _Variable as your variable. _Variable is used in the macro to get your variable. So use: PrintVar x,x, _j or something.

[wjsmarine]

Hi Walter,

That did the trick, thank you! Now if we can only get it to work on 16F chips... any takers?

Regards to all,
Bill

[ScaleRobotics]

Good to hear Bill.

But what is the problem with 16f's? Mine compiles without errors for a 16f876a, if I change the ports to match. But I don't have a way to test it here.

[wjsmarine]

Hi Walter,

Making the appropriate changes per chip (cmcon, adcon, etc.) and my same code with the same INC file as compiles correctly with the 18F252, I have no luck with a 16F648A or 16F876A.

I thought the INC font string may have been too long also so shortened it to about half its size but no difference. Here is what I get...

With a 16F648A:
Error[113] e:\wjs\pbp260\pbppic14.lib 449 : Symbol not previously defined [EEADRH]
Message[303] e:\wjs\pbp\NOD157~1.ASM 185 : Program word too large. Truncated to core size. (4920)
too many errors

With a 16F876A there are 20 lines of:
Message[303] e:\wjs\pbp\NOD157~1.ASM 187 : Program word too large. Truncated to core size. (4920)

Does this give you any ideas where my problem with 16F's is? What are the chip requirements for using this macro - codespace, ram size, etc,?

Thanks and regards,
Bill

[ScaleRobotics]

Hey Bill,

I think this might be a version issue for Mpasm, or PBP, but really not sure. I get a nicely compiled result at 2312 words for your version of include file.

I can fit 96 more bytes in RAM, so there is a bit more left, but as you can see, my program is small.

Here you go....

Step 1: Don't ask people to write all your code for you and expect to learn a thing from it.
Step 2: Read the manual.
Step 3: If the project is over your head, start with something you can do, with some work.
Step 4: Blink some LED's to start off, then try progressing to bigger projects.
Step 5: Take a look at http://www.picbasic.co.uk/forum/showthread.php?t=12677 for inspiration. Someone working hard and learning fast.

With time and effort, you will be able to return to the project you are yearning for.

[astanapane]

hello all,

i'm trying to compile a program based on 16f628a and nokia LCD 3310.

I'm trying to right a simple program just to print a HELLO WORLD on the nokia LCD but no luck.

My problem is that when i try to INCLUDE "LCD_3310v4.inc" i get an error that cannot open the inc file.

Also when i open the file in the microcode studio (the LCD_3310v4.inc file) i get the error "Symbol not previously defined EEADRH"

Do you have any suggestion please?

many thanks for your help in advance.

[Gusse]

This is causing your EEADRH problem.

Readcode Addr, CharEasiest way to go forward is comment or remove following parts of the code:

@ printstr macro function from Darrel and edited to work for this lcd
'format should look like this: @ PrintStr x,y, "your text string goes here"Meaning StringOut and ASM-part above it.
This is disabling string printing function, so you should figure out other ways to put stuff on LCD.

Those who know better why READCODE doesn't work with 628A could answer to you.
Even better if some workaround is available.

BR,
-Gusse-

[astanapane]

Hi Gusse,

thanks for your answer. That means that when i also get an error "cannot open inc file" the time i try to compile, it has to do with the 628a?

Sorry for my silly question but cannot understant why is not compatible.

[Gusse]

Is your inc-file in the same folder where you have your main pbp-file?

INCLUDE "LCD_3310v4.inc"If no, then you should include path to file before inc-file.
If yes, then I don't know why you get this error message. Is syntax or file name OK?

I think, it has nothing to do with 628A.

BR,
-Gusse-

[astanapane]

it is in the same folder.

I will try once more. the code and the syntax are also ok.

thanks for your time.

If i have any news i will let you know.

[astanapane]

hi all again,

i see that a lot of you having problem to write on the nokia lcd using the pic16f628a.

i'm also stragling to do it and i havent been able to fix my problems.

i'm trying to use the following files from the page http://www.picbasic.co.uk/forum/content.php?r=174-Using-Nokia-3310-LCD but no luck.

a very simple code i'm trying to display is the following.


DEFINE OSC 4

PortA = %11100000
CMCON = 7

Lcd_CLK var PortA.2

start:

@ PrintStr 0,0, "I love being"
@ PrintStr 0,1, "able to print "
@ PrintStr 0,2, "so easily!"

goto start

i will post later on the full code using the pic16f628a. It is seems that is been compiled but i dont see anything on the screen. I have checked connection and everything is ok.

I have also checked the nokia lcd with a circuit that work and didnt see a problem.

[fratello]

Maybe must to do this in your "LCD_3310.pbp" file :

'Port Mapping 'Change to match your application
Lcd_CLK VAR Portc.3 'LCD Clock
Lcd_DC VAR Portf.6 'LCD Data/Command
Lcd_SCE VAR Portf.7 'LCD Chip Enable
Lcd_RES VAR Portd.3 'LCD Reset
'Lcd_VCC VAR Porte.2 'LCD Power (always powered for this hardware)
Lcd_SDO VAR Portc.5 'LCD Data
I use a lot of 16F628A (and 648A) in my projects (see http://www.picbasic.co.uk/forum/showthread.php?t=14888&p=103204#post103204 and topic) and works verry fine !

[astanapane]

fratello,

thank you very much for your info and nice to meet you.

I've read all the articles here from you.

I only want to use the Nokia LCD for one of my RFID projects.

Nokia LCDs are fearly cheap and hopefully i manage to get them work.

Once i go home i will try to change as you suggested.

thanks again.


Lcd_DC var PortB.0
Lcd_SDA var PortA.3
Lcd_RST var PortA.4
Lcd_CLK var PortA.2

with this


'Port Mapping 'Change to match your application
Lcd_CLK VAR Porta.2 'LCD Clock
Lcd_DC VAR Portb.0 'LCD Data/Command
Lcd_SCE VAR Port 'LCD Chip Enable ??? here i also need to assign a port for enable??? or this goes to ground?
Lcd_RES VAR Porta.4 'LCD Reset
'Lcd_VCC VAR Port? 'LCD Power (always powered for this hardware) any port assigned to give power????
Lcd_SDO VAR Porta.3 'LCD Data

[fratello]

I ALWAYS use this LCD with SCE to ground :) . Try to find Nokia 5110 display ; it's more easy to "interfacing".
LE : I don't use LCD_VCC from PIC's. Just be careful to power with maxim 3.3 volts !!! Now I use this (second) schematic, with good results !

[astanapane]

when i compile with MPASM

i get EEADRH erros how can i correct it? please help. I think i will never manage to use my nokia lcd

[astanapane]

i would like to mention also that the nokia LCD i have is the nokia 5110 which does not have the Vout pin. (if that helps)

[mister_e]

Seems you're out of codespace... choose another PIC (like PIC16F877) and see if this compile.

[astanapane]

ok i will try later in the afternoon. But i just included the 3310.inc file and i just used @ print command. The 3310 took all the space from the pic?

is there any way to eliminate the 3310.inc and just take small bits from it in order to use only the @ print command.

My goal is to use it for the RFID tag number. I have done it with 2x16 lcd very simple with uLCD from 4D systems and now i would like to use Nokia lcd because is inexpensive compare to uLCD.

[Gusse]

Your PIC cannot use READCODE command.

READCODE: Some PIC16Fxxx and PIC18Xxxxx devices allow program code to be read at run-time. This may be useful for additional data storage or to verify the validity of the program code..MAC -file contains:

READCODE?TB macro Regin, Bitin, Bout
MOVE?TB Regin, Bitin, EEADR
clrf EEADRH
L?CALL READCODE
MOVE?AB Bout
endm
READCODE_USED = 1
And if you check from PIC16F627A/628A/648A datasheet, there is no EEADRH register in the these PICs (reason for error). Therefore you cannot use Scalerobotics (Walter's) great addon (=@ PrintStr) as it is now.

Also other note about READCODE

For PIC16F devices, 14-bit-sized data can be read from word code space Addresses.
Addr VAR WORDVariable cannot be WORD.

Easiest is to change to some other PIC, which support READCODE (e.g 16F8/74A/76A etc...) and which have also more code space :)

BR,
-Gusse-

[astanapane]

Hi gusse,

thanks, so that means that i cannot use any of the pic16f628a or a small pic 12f629.

I have seen fratello that used the pic but he didnt use the READCODE command.

Not using a small pic for such a simple code is annoying.

I will try with a bigget pic.

In case i want to print the number of the RFID tag do i need the READCODE command to my program?

If i can avoid or use other method to print letter as a label like fratello did then i might be able to use a small pic.

Thanks all of you for helping. And really sorry for my questions again.

[Gusse]

You can always use the old way to print LCD
Instead of

@ PrintStr 0,0, "HELLO"use

PosX=0:PosY=0:Gosub Lcd_GotoXY
Lcd_Data = "H"
Gosub Lcd_SendChar
Lcd_Data = "E"
Gosub Lcd_SendChar
Lcd_Data = "L"
Gosub Lcd_SendChar
Lcd_Data = "L"
Gosub Lcd_SendChar
Lcd_Data = "O"
Gosub Lcd_SendCharand remove "@ PrintStr" -part from LCD_3310 -file.

BR,
-Gusse-

BTW, "Edit Post" time could be a little bit longer. Couple of hours would be OK. Any changes to get this changed?

[astanapane]

i will follow your suggestion. Because right now i'm at work i will try that in the afternoon.

thanks again. I will let you all know for my results.

[astanapane]

i tried to write simpler the code but seems that the pic doesnt work. I also tried with bigger pic.

thank you all for your help. Its me that i cannot make it.

thanks again for your time.

[fratello]

Try this simple code ( http://www.picbasic.co.uk/forum/showthread.php?t=327&p=72927#post72927 ) , using 16F628A.

[astanapane]

thanks fratello,

i will give the last try. What i have noticed, is that the 3310.inc cause a problem to pic16f628a, and its is not working at all.

I did used on my code the following just to see if the LED flashes but no luck.

for example:

high LED
pause 100
low LED
pause 100

When i created a new pbp file on a different folder without the inc file included, my code was working.

Strange.

[mister_e]

Please, post your whole code and specify which version of the include you're using. There seems to have a couple of version 'round. Best thing attach your both file here as .TXT file.

This LCD seems fun to work with,I see the .INC could be tweaked in many ways. What I'll do is to order one, and see how this lib could be modified to use with other PICs. I should have it next week.

[astanapane]

Thanks Steve,

i didnt have a time yesterday to play with, because i came back home from work and was very tired. Apart from that, during the day i will post the code. Actually i have post the code before. It is very simple. I just wanted to use the @ print command with pic16f628a.

Gusse said to use the traditional way to print a string but i didnt have a time to do it.

this is my code:

DEFINE OSC 4
@ DEVICE pic16F628A, intOSC_osc_noclkout, WDT_OFF, PWRT_OFF, BOD_OFF, MCLR_ON
include "modedefs.bas"
include "3310.inc"

TRISB = %00011100 'portB configuration 0=out 1=in
TRISA = %10100000 'portA configuration
PortA = %11100000
CMCON = 7
VRCON = 0
INTCON = 0

OPTION_REG=%00000111 'weak pullups on, TMRO prescale = 256


start:

@ PrintStr 0,0, "I love being"
@ PrintStr 0,1, "able to print "
@ PrintStr 0,2, "so easily!"

goto start

The version of the INC file i use is the last one from that page.
http://www.picbasic.co.uk/forum/content.php?r=174-Using-Nokia-3310-LCD

Regards,

if you get the LCD, and you find the way, i will be much appreciated to see your work.

I just want to print somehow letters (or a small image as DATA) using any small pic like 16f628 or 16f88 or smaller.

My project is to print the value (number of the RFID TAG) using the nokia 5110 lcd.

I have done this project using 2x16 lcd and the uLCD 128x128 from 4D systems. That was easy because both of the displays have parallel and serial interfaces, and for 2x16 picbasicpro has a library for them.

Regards,

[Ioannis]

You make a fast loop and this may cause dim display. Use a pause 1000 before goto start.

Also how about contrast adjustment of the LCD? Maybe it is set too dim to display something.

I have no LCD to test here, just guessing.

Ioannis

[astanapane]

Hi Ioannis,

i will also check the contrast number and play with it.

thanks

[mister_e]

Everything is plausible on any PIC, however, there's some more efficient way than other to handle Strings, and some better PIC to handle it. Oh well, It should be fun.

[astanapane]

Steve,

i will try this weekend again everything i can do with compiling and checking the display.

When you receive yours you can also try out.

Which kind of Nokia did you order? 5110? http://www.sparkfun.com/products/10168

This kind of display does not have the Vop pin. Do i make any mistake on this stage?

[fratello]

How to connect display...

[mister_e]

I thought I would order that one but the other Canadian distributor I found don't have any in stock and couldn't tell me when he'll receive some more... too bad.

I found a place near who'll have the following in stock next week, I'll pick it directly at their shop.
http://www.inexglobal.com/downloads/glcd5110.pdf

[astanapane]

Steve,

is the same. i like it more in blue.

The pinout are the same.

[astanapane]

on the one i have as you see there is no Vop pin. This pin as from the code i see that is connected to ground through a 4.7uf capacitor and controls the Contrast.

The point is that on the LCd i have there is no Vop pin. So how can i control the Contrast.

If anyone have the display 5110 nokia from sparkfun, could make it easier if he can upload the schematic and a simple code.

[Gusse]

Vop is a register in extended instruction set (see page 14, Set Vop)
http://www.nxp.com/acrobat_download2/datasheets/PCD8544_1.pdf

"8.9 Set VOP value" (on page 16) describes how to calculate setting value.

Contrast is set in "Lcd_Init" section in LCD_3310 -file.

Lcd_Data= $c8: GOSUB Lcd_SendByte ' SET LCD Vop (CONTRAST)Here it seems to be $c8, with some older I have to use $d1 and other newer might need $bf. Try to change the value and check which is best with your display.

BR,
-Gusse-

[astanapane]

i have fixed the circuit from that page and work fine.

http://www.radiolocman.com/shem/schematics.html?di=44132

he is using the following

LcdReg = %00100001 'LCD Extended Commands.
call PrintCtrlLcd
LcdReg = %10101001 'Set LCD Vop (Contrast).
call PrintCtrlLcd
LcdReg = %00000110 'Set Temp coefficent.
call PrintCtrlLcd
LcdReg = %00010011 'LCD bias mode 1:48.
call PrintCtrlLcd
LcdReg = %00100000 'LCD Standard Commands, Horizontal addressing mode.
call PrintCtrlLcd

that means that the HEX of the Vop is $A9.

He is also says:

If by any chance the contrast isn't to your liking, it can be changed during the programming of Pic12F629, in the program location D2h. the current value A9h is the one I use with my LCD and don't know it will be for other LCDs. The value can be set to anything between 80 h and FFh, 80 h being minimum contrast and FFh maximum.

[mister_e]

OK, I've finished the new Include/driver/wrapper thing here. I'll post it in the next days. Still have some improvement to do. No big changes, but probably easier to use, a tad more flexible too.

You guys should love it :D

Stay tunned!

[astanapane]

hi mister_e

i'm looking forward to see it. Thanks.

[ruijc]

Hi all,

i've been looking at this topic for some time now.
I managed to get an original 3310 display and made some tests.

First i tried the INC solution but i got the "Truncated to code size" errors ( using 16F88 or 16F628A ).

Tried some examples posted here ( always changing ports to my configuration ) with a blank screen.

Tried the test file with big numbers and it worked.

Then moved to a 18F2550 micro-controller and once again the INC solution did not worked ( just had some ! simbols all over the place ).

The only solution i got was to use the INC file together with Gusse's sugestion on using "Gosub Lcd_SendChar" instead of "@ PrintStr" format.

This way works like a charm!

Do you guys know of an 18 pin chip that would work ( since it doesnt work with the 16Fs ) ?

Or Steve ( Mister-e ) will have a fresh new solution that will work on more chips ?

Regards

[mister_e]

My solution should work with anything, at compile time it decide which macro to build/compile/use.

It should even work with many 12F... with some limitations.

Hi Steve :)

I was using the 16F88

i was trying to use pic16f628a.

I have seen over the internet some others they succeed with pic12f629

[mister_e]

it could even work with a 10F, but probably not with PBP as it consume too much RAM, but that's another story ;)

You're probably out of luck on a Microchip PIC oriented forum like here, but

Hi Steve,

i'm looking forward to see the new driver.

I have 5 of the Nokia 5110 and i would like to play with them.

I'm sure you did a good work.

You can work with them right now, everything here work as long as you're aware of some Macro limitations. Which PIC do you plan to use ???

BTW, I'll take no credits, all the job have been done here and well done. I just put some of my spices in, some user configurables settings and some ease of use. It will be like my Keypad routine (http://www.picbasic.co.uk/forum/showthread.php?t=3250&highlight=).

Still working on the final touch, code optimisation, documentation, some code example, basic schematics... fun job.

Note to self, always read previous posts :D sorry 'bout that...

Hi Steve,

you are right about being able to using it except of some Macro limitations.

It works like a charm with the 16F88 microcontroller IF i dont use the "@ PrintStr x,y, "string goes here"" :) . But...IF i use that i get the truncated errors.
