51单片机学习32-12864显示（51单片机学习32-12864显示）

这篇讲12864液晶显示汉字

仿真图用的是我自己做的一个51单片机开发板 图纸比较大，截图可能看不清，需要的话可以私信联系我。

void write_data(uchar dat); //写数据

void write_cmd1(uchar cmd); //写命令

void write_cmd2(uchar dat,uchar cmd); //1个字节

void write_cmd3(uchar data1,uchar data2,uchar cmd);//2个字节

uchar read_status(); //读状态

void check_status(); //检测状态

void display_HZ(uchar x,uchar y,uchar *hz);//显示汉字程序

//注意汉字数组要加code放到外部存储器中，如果不加code则空间不够
