PostPosted: Thu Mar 10, 2011 8:19 pm     Reply with quote

Just Copy the library and save it in a source file (ex. lcd1100.c)
and include it in your main code

works fine on both 18F & 16F families

#use rs232(baud=19200, xmit=PIN_C6, rcv=PIN_C7,stream=com0)

#include "lcd1100.c"

void main (void) {
   
   Lcd_Init();
   Gotoxy(5,0);
   printf(print_char,"Nokia 1100 LCD");
   Gotoxy(40,4);
   printf(print_char,":D");

while(1);
 }

Thanks for the driver. Wink
Does anybody test this code on a Siemens A56 LCD?
I have some of those LCD's.

Even though the pinouts are the same in both Nokia 1100 and Siemens A56 LCDs, they seem to have different controllers, PCF8812 for Siemens.
both LCDs also have different resolutions which will cause addressing problems.

A test never hurts, just keep in mind that Siemens LCDs works on 2.9V.

sir just out of curiosity why were you using this particular line in your code
Code:

#use rs232(baud=19200, xmit=PIN_C6, rcv=PIN_C7,stream=com0)


where you looping the output/display via rs232?

Thanks demonspells, I will search the datasheet of PCF8812.

Sorry for the delayed answer, I'm quite busy with another projects. This particular project is just to learn how to use an LCD graphic display.

I guess cause he is printing the characters to a debug terminal, maybe a PC.

Look the following line at Main

Code:
 printf(print_char,":D");

I find myself doing the circuit assembly, with your program, but the Nokia 1100 is connected to the PIC on the breadboard and does not work. Could you help me with the actual connection of the circuit ? Thank you very much.

I try it on Proteus it works.
When I try it on real time, I will give information about it.

I tried it in real now.

Be careful about VOP register.

It is about Contrast. If needed, you can change it in LCD init function like
Code:
 Lcd_Write(CMD,0x30); // write VOP register  //not 20

It works better.

I want to use this screen as position on Nokia1100. Is there a solution, how can I change direction of screen?

If CCS does not provide code you may have to do it yourself.

The part is not that complex. Send a start signal, and it responds by squirting out all its data in a specified format.

I suggest you make a start on the coding, then ask for help if (when) you get stuck.
