仿真原理圖如下（proteus仿真工程文件可到本帖附件中下載）

程序：
#include <reg51.h>
#define uchar unsigned char
#define uint unsigned int
#define d_code P1
#define d_wei P3

uchar code tab[]={0x3f,0x06,0x5b,0x4f,0x66,0x6d,0x7d,0x07,0x7f,0x6f};
uchar sec;
uchar count = 0;
void delay(uchar m);

void InitTimer0(void)
{
TMOD = 0x01;
TH0 = -50000 / 256;
      TL0 = -50000 % 256;
         ET0 = 1;
      EA = 1;
TR0 = 1;

}

void main(void)
{
uchar shi,ge;
      InitTimer0();
      sec = 0;
      while(1)
      {
      shi = sec / 10;
      ge = sec % 10;
      d_code =  0xff;
      d_code =  ~tab[shi];
      d_wei = 0x02;
      delay(10);
      d_code =  0xff;
      d_code =  ~tab[ge];
      d_wei = 0x01;
      delay(10);
      }
}

void Timer0Interrupt(void) interrupt 1
{

TH0=-50000 / 256;
      TL0=-50000 % 256;
      count ++ ;
      if( count > 19 )
      {
            count = 0;
            sec ++ ;

            if( sec > 59 )
            sec = 0;
      }

}

void delay(uchar m) //M ms 延時程序 (12M)
{
unsigned char a,b,c;
for(c=m;c>0;c--)
      for(b=142;b>0;b--)
         for(a=2;a>0;a--);
}
