今天測试数码管LED屏驱动，用某产品的一个共阴极的LED屏，依据电路图做数码管LED屏的检測。

代码写得有些冗长，有好几种驱动的方法，这里仅仅是当中一种最直接的方案，抽出时间要做个更有效率的调用和驱动的方案。

//设置阴极接口

int d1 = 1;

int d2 = 2;

int d3 = 3;

int d4 = 4;

int d5 = 5;

int d6 = 6;

int d7 = 7;

//设置阳极接口

int a = 8;

int b = 9;

int c = 10;

int d = 11;

int e = 12;

int f = 13;

int g = A0;

int h = A1;
