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; void setup() { pinMode(d1, OUTPUT); pinMode(d2, OUTPUT); pinMode(d3, OUTPUT); pinMode(d4, OUTPUT); pinMode(d5, OUTPUT); pinMode(d6, OUTPUT); pinMode(d7, OUTPUT); pinMode(a, OUTPUT); pinMode(b, OUTPUT); pinMode(c, OUTPUT); pinMode(d, OUTPUT);

计划採用机器视觉来检測,自己主动鉴别出断笔,笔段亮度差异较大等质量检验问题。
