51单片机LCM19264驱动程序

ID:72519 · 发表于 2015-1-23 01:01

也许是我在焊LCD排针时，静电击坏了LCM模组，连STC12C5A60S2的与之相连接的端口也损坏了，
难怪用示波器测试数据端口有的有波形，有的无波形；
程序协议都看了但没看出问题，所以我只能认为是PCB有问题了；
昨晚通过点亮LCD上第一个点，发现正常；
稍许松了口气；再次验证，有了本文的起笔。。。嘿嘿！看单片机点亮LCD第一个点的程序！

0x3e;0x3f;0xc0;0xb8;0x40 这些都是什么功能

这个程序不是19264的，19264是分三片的，这个程序呈有CSA,CSB,只是两片，应该是一个12864的。

我手上也是CSA,CSB的MS19264C

没有那么脆弱吧！
