正文摘要:

芯片：AT89S52 实验台：亚龙YL-236型单片机控制功能实训考核装置 （刚开始学.师傅也不会） 部分显示乱码. 我是按照书上的程序弄的.然后在之前也是同一个程序但只能显示字模里面的前十个汉字. 超这个范围 ...

从画面来看，不是你说的“只能显示字模里面的前十个汉字.超这个范围就乱码”，画面上比较正常显示的只有“一二三四”，也就是说只有左半屏是正常显示的，同一个字符串里的“五”无法正常显示，说明左右半屏的处理不对，你得看你用的12864具体型号并找到资料，看看里面左右半屏的片选CS1、CS2是怎样使用的，然后更改第169行if(right)cs1=0,cs2=1;以及第178行cs1=0,cs2=1;里的片选试试。
