一、效果展示

二、所用材料

1.16X16点阵

Proteus并不提供16X16的点阵，只能我们自己通过4个8X8的组装为16X16的点阵。

由此可知8*8变成16*16

列需要这样连接：

行需要这样连接：

再把四个放在一起即可：

2.74hc595

详细介绍见我上一篇文章

https://blog.csdn.net/qq_41639829/article/details/82151706

这里需要用到级联，也不算太难，就相当于原来是输入8个数，这需要输入16个，然后再输出，前八个输入的就被自动挤到级联的下一个595中了！

3.stc89c52

三、原理

1.静态显示

同8位的静态显示一样，只不过是从8个变成16个而已。

详见上一篇文章。

2.动态显示

同8位的动态显示一样，只不过是从8个变成16个而已。
