求LCD12232显示汉字的程序

求LCD12232显示汉字的程序

Answer 1

硬件：TG12232B （122*32）模拟口线接线方式
连接线图:
--------------------------------------------------|
|DB0-----P0.0 | DB4-----P0.4 | RW-------P1.1 | A0--------P1.0 |
|DB1-----P0.1 | DB5-----P0.5 | RS-------P2.1 | V0接1K电阻到GND |
|DB2-----P0.2 | DB6-----P0.6 | E1-------P1.3 |
|DB3-----P0.3 | DB7-----P0.7 | E2-------P1.2 |
---------------------------------------------------
[注:AT89x52使用22.1184M或11.0592M晶振,实测使用22.1184M或11.0592都可以]
编译平台：Keil uV2 7.08
//可能看起来有点乱，不过效果还是不错的，显示图形总的来说比显示汉字要简单,当然显示汉字也不难。
希望此程序能给你一些帮助。
