/************* 本程序功能说明 **************
驱动LCD128*64黑白点阵屏.
用户可以修改宏来选择时钟频率.
显示效果为: 第一行显示模拟的RTC时间, 7、8行显示8个16*16点的汉字. 本程序使用的LCD是有两个片选的.
注意: LCD接口的16脚是空脚, 本程序要把这个脚接到P2.2做另一页的片选.

已知的条件出现这结果不意外

Proteus里的12864，就是我仿真里用的这个，能通过程序直接显示汉字吗？我查百度说什么无字库？

ID:96682 · 发表于 2022-3-31 03:40

用板凳的基于 KS0108 的点阵屏，有字库的得下载第三方仿真文件并安装才行

ID:91580 · 发表于 2022-3-31 07:31

本身电路图就没画对，黑屏不奇怪了。

CS1/CS2

我用的并行方式，还需要连接CS吗

ID:941205 · 发表于 2022-4-1 16:53

你在论坛里搜LCD12864就能找到无字库仿真的PROTUES程序了。

ID:264021 · 发表于 2022-4-1 18:58

仿真图画的不对，CS1,CS2要用I/O口控制的，他分别控制12864的左边和右边的显示，你看一下数据手册就明白了
