    是用点阵式LED还是用LCD的？

    这是液晶12864的显示程序
    #include <reg51.h>

    sbit RS=P2^2; // 数据\指令 选择
    sbit RW=P2^1; // 读\写 选择
    sbit E=P2^0; // 读\写使能
    sbit CS1=P2^4; // 片选1
    sbit CS2=P2^3; // 片选2

    unsigned int number=0,mstcnt=0; //number 控制显示的字符个数，mstcnt用于延时控制

    unsigned char code ziku[]=

    {
    /* 此方法显示的汉字为下半列排，即先分为上下两半，然后先取上半部分的点阵数据，且点阵对应的数为从下看到上 D7~D0
