教你如何将stc32的例子搬到89c51上，这里以lcd12864为例
1.第一步：当然是修改要包含的文件。89c51：
#include <reg52.h>
#include <string.h>
stc32:
#include "./comm/STC32G.H"
2.第二步：修改影响延时的地方（工程属性，烧写设置）。
89c51：
#define MAIN_Fosc 12000000L
stc32:
#define MAIN_Fosc 24000000L
3. 删掉stc32的端口模式设置，89c51不需要。
备注：第二步非常重要。

折腾了好久，刚刚终于成功了。 CS H/L 模组片选端，高电平有效。
PSB L L：串口方式
--------------------------------------------------------------
RS(CS） H/L RS=“H”,表示DB7——DB0 为显示数据； RS=“L”,表示DB7——DB0 为显示指令数据。
R/W(SID) H/L R/W=“H”,E=“H”,数据被读到DB7——DB0；R/W=“L”,E=“H→L”, DB7——DB0 的数据被写到IR 或DR
E(SCLK) H/L 使能信号
PSB H/L H：8 位或4 位并口方式； L：串口方式
/RESET H/L 复位端，低电平有效
就只要改头文件和延时就可以了？ 可以考虑将 STC89/STC12C5A60S2/STC15W 系列的程序往 STC8H/STC32G上移植，
反过来的就没必要了
STC8H/STC32G 价格更低
后续的 STC8051U 管脚兼容 STC89/STC12C5A, 但程序是兼容 STC8H/STC32G的

这个过程肯定是可逆的哇(⊙o⊙)。{:lol:}。感谢大佬提醒。 后面可以忙 STC89C52RC上的程序移植到 STC8051U 上

帮忙新人成长，帮忙论坛建设的，都可以，这个要 7/1后送芯片，7/15后才有实验箱
