关于verilog的12864程序,第1张

你的LCM是用什么控制IC的？COB还是COG？ 不清楚你驱动IC所以不能帮你看了，只要初始化没问题就行了，我给你发个常用的COB 三星0108的驱动 程序，跟 COG的7565R的程序，你参考下

这是一个简单的12864显示字的程序。LZ可以参考参考

12864要看液晶屏的驱动IC是什么，不同的话，肯定不通用。

另外，它的指令多，因为复位的时候，大多指令都会自动设到默认值。程序初始化的时候，只需要更改其中几个。

比如显示指令，复位后，默认值是 显示关闭。初始化就要，显示打开。

我看你的命令像是，ST7920这款IC控制的（猜测），带中文字库的吧？网上驱动很多，有串并口都有。

检查液晶屏控制器的时序 *** 作命令码初始化过程,还有硬件,上下拉电阻,既然决定用并口,那么PSB就直接VDD,这样还能省一个IO口 注意下面的程序中RS=0,RW=0,能同时为低吗 void write_command(uchar cmd)

{

check_busy();

rs=0;

rw=0;

en=0;

P2=cmd;

delay_4us();

en=1;

delay_4us();

en=0;

参加电子设计大赛刚学会的，还需要的话可以教你打点画图，可以在液晶屏上显示点，线，画
