16*16点阵求助

这个是用两个74HC138级联作位选，两个74HC595级联作段选，来控制点阵。研究了两天了，写出代码不行。有些低级错误自己很不容易发现，希望高手指点一二。。。。。感激不尽了。。

没人愿意帮我吗。。。。。。。。。。。:dizzy:

可以参考网上的一些资料，弄明白控制原理，边调试边理解。

楼主的代码写得不怎么样, 居然一行注释都没有!

除了软件, 还有硬件, 没有人会搭你这个电路来帮你调试程序的.
应该把调试程序看成写程序的一部分, 而且通常都比写程序还费时费力!
好好努力, 慢慢摸索一套属于自己的最行之有效的调试技巧, 希望哪天看到楼主上来交流编程和调试的艺术.
