12864显示程序

按昭下面的编程很方便的。。。。 硬件连接方式是：并口直接访问。 这是汉字显示程序： #include #include

#define uchar unsigned char

#define datawr 0x1200 //写数据通道

#define comwr 0x1000 //写控制命令通道 #define datare 0x1300 //读数据通道 #define comre 0x1100 //读忙通道

uchar code disp_data[]={\浙江大学 \//第一行，第一页 \级通信工程一班\//第三行 \宁波理工学院 \//第二行 \竞赛小组 \//第四行

\液晶显示器\//第一行，第二页 \测试程序 \//第三行 \年07月25日 \//第二行 \Tornado \//第四行 void set12864();

void write_command(uchar command); void write_page(uchar data_add); void read_page(uchar data_add); void delays(uchar cont);

void main() {

while(1) {

set12864(); //初始化12864 write_page(0); //写入一页数据

read_page(0x30); //读出一页数据到内部RAM delays(2); //延时2s

write_page(64); //写入下一页数据 delays(2); //延时2s } }

//初始化12864子程序 void set12864()

{

write_command(0x30); //功能设定控制字 write_command(0x0c); //显示开关控制字 write_command(0x01); //清除屏幕控制字 write_command(0x06); //进入设定点控制字 }

//写控制命令子程序

void write_command(uchar command) {

bit flag=1; //12864空闲标志位 while(flag) //检查12864是否空闲 flag=\

//写一页子程序

void write_page(uchar data_add) {
