什么液晶？
7920带字库还是7565 7657外挂字库？
有没有单独的字库芯片？

是ST7920，地址没问题的

什么型号的屏幕，是否有字库，看看实物是怎么乱码的

要显示状态两个字却显示蔼舵啊

已经换成GB2312了，还是不行

看后面你的照片，，怎么感觉你输入的还是UTF8编码的汉字？输入两个汉字变成了三个汉字

这个是keil的编码，，

这个你试一试在这个编码下新建一个文件，把你显示屏的函数复制过去。。。

[!(/source/plugin/zhanmishu_markdown/template/editor/images/upload.svg) 附件：AIwater.hex](forum.php?mod=attachment&aid=69107 "attachment")

你试一试这个hex文件，，我只把你的工程里的water.c 改了一个编码然后编译了一下
