//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.
