感谢ZZZ大侠的文章，让我将08接口的16*64 LED显示屏点亮了。原帖【Z】Arduino也能驱动LED显示屏，LED业界标准Arduino驱动方案解析  @iceicon

但是没有让屏幕显示文字，只有线啊！！！！！
代码如下[table=50%]
  1. int R1=7;
  2. int STR=8;
  3. int CLK=9;
  4. int EN=2;


  7. int dig0=3;
  8. int dig2=4;
  9. int dig4=5;
  10. int dig8=6;
  11. //int i,m;

  13. unsigned char jj,j;


  16. void setup()
  17. {
  18.   pinMode(R1,OUTPUT);

  26. }
