Using Nokia LCD

[Gusse]

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 hall

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!

Hi,

can someone pls post simple 3310 lcd example, where i can only put a pixel on my screen. i dont need code where i can display characters, pictures etc. Just as simple and compact as possible.

Thank you...

If you'd apply yourself, do a little bit of reading/looking/etc, you might (or might not) notice that not ALL of the code in the 80-odd posts is written in C.

Ok, past few days i have been playing with different code examples and came to solution which is attached below (proov.zip). This code works fine on small pics (like 12f629, 12f675) but wont work on bigger pics (16f627/8), Can someone pls give me clue whats worng in that code.

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/showth...ght=nokia+3310) is where you got the code in the first place.

[theguru56]

Ok, ill try there.

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.

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.

Check page 22 from Philips PCD8544 datasheet. 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.

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

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.

Hi to all !
I use the hardware from here : http://www.picbasic.co.uk/forum/show...a+3310+display.
I try to modify the code of N3310+PIC 12F675+DS18B20 for using PIC 16F628A, like in attachament. But...nothing on display ! Can someone tell me what I do wrong ? Thanks in advance !

[GioppY]

Hi!
If you followed my schematic exactly, try the attached code.
It works fine for me.
Notice : Cs (PortB.3) must be Low ; Rst(PortA.4) needs a pullup ; Mode is disabled (you need another pin)
Regards
Gianni

[fratello]

You are one Gentleman ! Thank You verry much ! It's work fine now !

[fratello]

Hi again ! I try to build one simple thermometer, based on schematic from GioppY and code from Ivica N., but with this code (attached) I see only some points, all over the display, and '85.0'. Some sugesstion ? What I do wrong ? Thanks in advance !

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.

Using the command "goto main" I have some results ; now the display show the correct temperature...but still remains some 'points'... (see foto). I try different code for LCD_Clear, but not results... Please, help me more ! Thanks in advance !

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...
At least you managed to get DS18B20 to work. That's positive!

BR,

[fratello]

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

[Gusse]

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:"

BR,
-Gusse-

[Gusse]

I meant this (below) instead of "CALL"

GOSUB LCD_Clear

Why you are using CALL, shouldn't those be GOSUB instead?

[fratello]

YES !!!! That work ! THANK YOU !
I have learning again one more thing. Thanks to You, all members of this great forum. I'm happy !
Now, I want to make the next step : "up-grading" the schematic from here - http://www.picbasic.co.uk/forum/show...7&postcount=35 for using with N3310 display. I will keep You on line ! All the best !

[fratello]

Now my project it is in this stage - see photo 1. I ask -again, sorry ! - for help : how to make like in photo 2 ? I do not understand how 'advanced' to next line (I think because of my poor english... ). I read the N3310 display .pdf and many examples, but still don't understand... 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_GotoXY

Then 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...

Library file is in post #93, not #95. Sorry!
BTW, why I cannot modify/edit my own posts after pressing "Submit Reply" -button??

[fratello]

Thank You ! ... I modifiy the code like in attachament, but now I have nothing on display ... After the line of code that I inserted it's need to put another's commands ? Only this single line it's not enough ?
( ..... Char = 18
call PrintChar

PosX=30 : PosY=1 : Gosub LCD_GotoXY

if TempH > 99 then
Char = 1
call PrintChar
else
Char = 10 ' + plus
if Predznak = 1 then Char = 11 ' - minus
call PrintChar
endif


Char = (temph dig 1)
call PrintChar

Char = (temph dig 0)
call PrintChar

Char = 12
call PrintChar

Char = (temperature dig 3)
Call PrintChar

goto main )

Please, take a look how I did with my accelerator demo application
Nokia LCD with 3D-accelerometer.
In this demo, I didn't use library file, but all relevant LCD routines are under "LCD stuff" section in the code (zip-file).

You can always copy content of library to your code, if you have problems with included files.

One line is enough, it is so simple

[JLbart]

I found a SatNav software on ZorroGPS.com, Has anybody used this software?

[fratello]

With the code below I have the results like in photo ! Thank You all for Yours cooperation !
Note : The dual function of reading two sensors DS18B20 it is not yet ready !

[fratello]

Me again ! My thermometer with two sensors is ready !!!!! Works great !!!!!
Unfortunate I can't making one best looking for display ...I don't -yet- understand how to display 'graphical things'....One border mybe is necessary...Every improvement will be apreciated ! Thanks - again _ to all !
All the best ! (...and sorry for my poor english...)

[Archangel]

All the best ! (...and sorry for my poor english...)

Not so poor . . . Middle Class , Project coming along nicely, hang in there, you're getting it.

[fratello]

I did it ! This is my final version ! I'm happy !!!
I wish You all the best !

[mister_e]

Good job!

Don't give up!

[Gusse]

Great! More Nokia LCD applications are always welcome
I have plenty of Nokia color LCD. Maybe that is next step... , but not soon...

Hi to all !
Based on the code from here : http://www.picbasic.co.uk/forum/show...7&postcount=35, I intend to use the Nokia-LCD for the thermostat; I attach the schematic. Please, help with TRISB,TRISA,PORTB,PORTA,OPTION_REG setting, because, even I read the datasheet, I don't understand why Mr.GioppY say :
TRISB = %11000010
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.
