Interfacing Toshiba T6963 LCD display to Atmel AT91SAM ARM microcontroller

Introduction

LCD displays with Toshiba T6963 controller are ones of the most popular LCD displays. On this page You will find ready-to-use source code for Atmel AT91SAM microcontrollers with ARM core written in C language for arm-elf-gcc compiler (WinARM).

I divide source code for following files :

T6963C.h - configuration and functions declarations for T6963.c file
T6963C.c - all functions specific for T6963 controller
graphic.c - functions for drawing lines, circles and rectangles
graphic.h - functions declarations for graphic.c file

All source codes are available in Download section. After download all files to folder with Your project and add T6963.c and graphic.c files to project tree and to makefile)and place in file with the main() function calls to functions which You would to use. Code is work currently only with 240x64 pixels displays. With other resolutions can work wrong.

For example, code shown below :

#include "build/board.h"
#include "T6963C.h"
#include "graph.h"

extern void Init(void);

int main(void)
{
int i;
Init();

GLCD_Initalize();
GLCD_Clear_Graphic();
GLCD_Clear_Text();
GLCD_Clear_CG();

GLCD_Line(0,0, 239, 0);
GLCD_Line(0,0,0,63);
GLCD_Line(239,0, 239, 63);
GLCD_Line(239, 63, 0, 63);

GLCD_Circle(30,30,20);
GLCD_Line(30, 10, 30, 20);

GLCD_Circle(209,30,20);
GLCD_Line(209, 10, 209, 20);

GLCD_Rectangle(60, 6, 120, 48);

GLCD_Text_GoTo(13,1);
GLCD_Write_String("radzio.dxp.pl");

GLCD_Text_GoTo(13,3);
GLCD_Write_String("TOSHIBA T6963C");

GLCD_Text_GoTo(11,5);
GLCD_Write_String("AT91SAM7 & arm-gcc");

while(1);
return 0;
}

...will produced following image :
