标题: 关于单片机LCD12232并口驱动程序只有一个瞬间显示正常?
图12是实物
图345是引脚排列
各种排列都试了一下，有一个瞬间，显示了程序应该显示的字符，然后再固定，就不显示了，所以我能确定，程序是正常的，就是引脚不确定。
下面是清翔的测试程序。有没有人用过精电蓬远的屏幕，这屏幕看起来做工很好，能用起来就值了。

找店家要个DEMO就好

我是头一次见液晶驱动IC没用牛屎堆的，这商家可真良心

这屏上有个丝印写的是2001 ，如果2001是生产日期的话，这屏有20岁了

用万用表量了现个IC，能确定6，7引脚是E1,E2，因为这两个引脚一个接IC1,IC2不通，另一个相反。DB0到DB7基本也能确定，两个IC到引脚上的排列顺序。
其实屏不值钱，是别人送的，但是就是驱动不起来，不舒服。
