手工贴片LED点阵
本帖最后由 xc7981348 于 2013-3-15 20:02 编辑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 好精致的手工 wing 发表于 2013-3-15 22:04 static/image/common/back.gif
好精致的手工
谢夸奖，不会编程啊不会编程啊 厉害厉害，请问LZ是如何对导线剥线的呢。那么细的导线我总剥不好 本帖最后由 xc7981348 于 2013-3-15 23:18 编辑

厉害厉害，请问LZ是如何对导线剥线的呢。那么细的导线我总剥不好
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 焊的真不错 焊接很漂亮，适合送妹子:lol 弄个壳~~送妹子必须的~~ 那个，led什么的都木有限流电阻的么@@？
