Using Nokia LCD

ok, here are some links:

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

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

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

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.

Thanks for your tip. Lcd is working.

Thanks for your tip. Lcd is working.

This wouldn't be the practically the same LCD as the one found at Sparkfun is it?

If you try to get the datasheets, I suggest you following datasheets center:

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.

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 !

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)

Gianni

hi
can anyone please send info regarding interfacing the nokia 6610 display with 8051..

[mister_e]

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.

[mister_e]

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.

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