用育松12864显示图片

单片机源程序如下:

#include <AT89X52.h> //调用51单片机的头文件
#include <Intrins.h> //因为本例中用到空操作_nop_();所以必须调用这个头文件
//12864液晶相关I/O设置
sbit RS=P3^5; //并行数据/控制字选择 H:数据 L:控制字
sbit RW=P3^6; //并行读/写选择 H:读 L:写
sbit E =P3^4; //并行读写使能 H有效,下降沿锁定数据
sbit PSB=P3^7; //串口,并口选择 H:并口 L:串口（开发板上引脚标识为CS1）
sbit RST=P2^1; //复位引脚 L:液晶复位
sbit DB0=P0^7; //
sbit DB1=P0^6; //
