嗯，也算是此次暑假留校在科协学习的一个小小的结束成果了。其实本来是听创新基地指导员的建议做倒车雷达的，但是那超声波的探头太贵，被迫放弃了。
另外为了让点阵恒流驱动，我用了三极管驱动（其实不用三极管也能显示的，不过亮度不均匀，不好看）我自己靠仅有的一点模电三极管知识自己把电路图给设计出来了。因为网上很难找到电路，不知道为啥16×16点阵的资料特少。

74HC595驱动电路。用的四块74HC595级联。我问过很多比较专业的人，也找过很多资料，他们都说行扫描和列扫描都用595的话不好。可是我理论分析可行，于是做出来，事实证明也行！！

这是没加三极管驱动的一样能显示，只是效果差一点

这个自己比较自豪的板子，三极管恒流驱动模块（自个设计的）。呵呵因为科协上面没有8050了。自己买3毛一个，买16个..。。也花了不少钱啊。。挺心痛

整体连接

网上的资料很少出现完整配套的16×16点阵的原理图和程序，而且这是经过桥哥实践验证了的，因此在此含泪托出。。呵呵。
成品整体照

原理图（由于图太大缩小了看不清，因此分块来发）

下面是驱动模块电路图
1、三极管部分

2、74HC595部分

3、引出接到点阵的排针

嗯硬件电路就是这样了，下面是程序。

至此，点阵的完整资料已经给出来了，有不足和还需改进的地方或者错误还希望看到这篇文章的达人指出。。

看到了不，实验室里唯一一台显像管显示器（俗称大屁股）。。。正是桥哥的。。很纠结。为啥他们都用液晶呢？？？我很疑惑，一直没搞懂。。。

不理解，能解释一下吗
