hello,
i'm using at89c55 for interfacing graphical lcd t6993 i want to display a single character on lcd using 'C' anyone have idea about this pls help me i've written code like this
code:
//************************************************** ************************************************** *************************************
//LCD t6963 INTERFACING WITH AT89C55WD
//************************************************** ************************************************** *************************************
#include "reg51.h"
sbit LRST = P3^6; //LCD RESET
sbit P3_0= P3^0; //LCD C/D
sbit P3_2= P3^2; //LCD WR
sbit P3_3= P3^3; //CHIP ENABLE
sbit P3_1=P3^1; //LCD RD
// P1 DATA PORT


main()
{
int m,*dptr,R6;

RS0 =0;
RS1 =0;
LRST=0;
DELAYP5SEC();
LRST = 1;

LCD_INIT()

//I want to display character 's' on graphical lcd
//how to display it.

Several examples out there for PIC's. You should be able to port to the Atmel without too much trouble. I Google'd 'lcd pic t6963'. Check here about 2/3rds down the page for t6963 examples:

http://www.picant.com/c2c/examples.html

Found this after Googling 'lcd atmel t6963':

Does that help?
