手工贴片LED点阵

xc7981348

DIY了个8*8点阵屏幕送妹子，手工贴片焊接LED，用的是官方直驱点阵的程序，但是只能显示13个字符，再多的字符可以写进去不过显示不出来，求大家帮助编程，非常感谢，以下是我的代码和大量渣图。
还有一个问题，如何制作mega328的最小系统，可以写程序进去不过总是运行错误，比如只能点亮一行点阵而且显示不正常，求大家帮忙啊。

我是学金融的，玩烙铁才玩了3个月，我用的是T12白光，可以调温，焊锡用的是论坛商店买的整卷的山崎焊锡，其实也没啥经验啦，我一般用300度焊接

这个我买了一把10多块的剥线钳，用的是24AWG的线，那线里面铜丝有点缩水，正好够细很合用
