程序如下：
#include<reg52.h>
#define uint unsigned int
#define uchar unsigned char
sbit dula=P2^6;
sbit wela=P2^7;
uint num=0,num1=0,n=0;
uint shi,ge,i,j,k,m,l;
uchar code arry[]={0xfe,0xfc,0xf8,0xf0,0xe0,0xc0,0x80,0x00};
uchar code table[]={0x3f,0x06,0x5b,0x4f,0x66,0x6d};
void delay();
void display(uint,uint);
void circulate();
void main()
{
  TMOD=0x01;
  TH0=(65536-45872)/256;
  TL0=(65536-45872)%256;
  EA=1;
  ET0=1;
  TR0=1;
  while(1)
  {
   display(shi,ge);
   if(num==20)
   {
      num=0;
      num1++;
      if(num1==60)
      {
         circulate();
circulate();
         P1=0xff;
         delay();
         for(i=0;i<5;i++)
            {
               P1=0x00;
               delay();
               P1=0xff;
               delay();
            }
            num1=0;
         }
   shi=num1/10;
   ge=num1%10;

   }
}
}
void circulate()
{
  for(j=0;j<8;j++)
{
   P1=arry[n++];
   delay();
}
  for(k=0;k<8;k++)
{
   P1=arry[--n];
   delay();
}
}
void display()
{
wela=1;
dula=0;
P0=0xfe;
wela=0;
dula=1;
P0=table[shi];
dula=0;
delay();
wela=1;
dula=0;
P0=0xfd;
wela=0;
dula=1;
P0=table[ge];
dula=0;
delay();
}
void delay()
{
  uint m,l;
  for(m=500;i>0;i--)
  for(l=110;j>0;j--);
}
void T0_time() interrupt 1
{
  TH0=(65536-45872)/256;
  TL0=(65536-45872)%256;
  num++;
}
警告如下：
