刚买了个64x64的双色led屏，分4组12接口的。我有单片机stc89s52rc,有18b20,有1302。刚入门单片机，程序还不大会弄，求个16x64led的测试程序，先谢啦！

各种屏接口不一样，单片机要硬件软件配合起来玩

坛上找了半天都没找到合适的。有的对flash要求高，有的需要12887，有的程序不完整，有简单一点的又编译不了。特发帖求助。

开心锅锅的那个程序比较简单，改了下也不能成功。电路板上有595,245,138,367。不知道是否有反向的问题，那位大侠帮帮忙，改下！源程序如下：

用沈老师的测试程序试试，板子上的接头定义1G、3CLK、5STR、7R、9A、11B、13C、15D、16OE

要上上源程序，这样的程序我能学什么呢！

auxccc · 发表于 2012-4-16 19:32

还是不行，没有显示。用锅锅的程序还有乱码显示。有可能是接口不对。接口：N为接地，X为未知作用

2 N N N N N N N X 16
1 X X X X X X X X 15

板上1处有标记，其他没任何标记。和12的接口相近是反的，红绿双色的板上有芯片245，595，138，367

貌似应先确认你的单片机的I/O哟，因为涉及片选信号的问题，否则就不显示或乱码的。
