Introduction
LCD displays with Toshiba T6963C controller are ones of the most popular LCD displays. On this page You will find ready-to-use source code for Atmel AVR microcontrollers written in C language for avr-gcc compiler.

Connections between LCD and MCU are shown on below picture (it's only example, You can change ) :

Of course, this is very simple schematic without power lines and other required parts like crystal oscillator etc., which You must place in real design. But I think, that isn't problem for You.

I divide source code for following files :

• T6963C.h - configuration and functions declarations for T6963C.c file
• T6963C.c - all functions specific for T6963C controller
• graphic.c - functions for drawing lines, circles and rectangles (controller-independent)
• 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 T6963C.c and graphic.c files to project tree (or makefile) and place in file with the main() function calls to functions which You would to use.

For example, code shown below :

#include <avr/io.h> #include "T6963C.h" #include "graphic.h" int main(void) { GLCD_Initalize(); // Initalize LCD GLCD_ClearText(); // Clear text area GLCD_ClearCG(); // Clear character generator area GLCD_ClearGraphic(); // Clear graphic area GLCD_TextGoTo(0,0);// set text coordinates GLCD_WriteString("http://en.radzio.dxp.pl/t6963/"); // write text GLCD_Circle(32,32,20); // draw circle GLCD_Circle(208,32,20); // draw circle GLCD_Rectangle(8,8,224, 48); // draw rectangle while(1); return 0; }
