scanled.c

数码管扫描程序 , 可以在c51单片机执行 里面有时序图可以参考

#include <reg51.h>
sfr p0=0x80;
sfr p1=0x90;

int main()
{
 unsigned char a[10]={63,6,91,79,102,109,125,7,127,111}  ;
 unsigned char b[8]={127,191,223,239,247,251,253,254};
 unsigned char *h[10],*p;
 unsigned char t=0,k=0,i;

 p0=255;
 p1=0;
 p0=*(b[0]);
 while(1)
 {
 	p0=*(b[0]);
 for(i=0;i<10;i++)
 {
  h[i]=a;
  p0=*b[i];
  a++;
  }; 
 };	
}
