又搞左成日單片機。。編了一春鳥語。

因為初學用曬89

c51的IO口，而且程序鬼春甘長，搞左個數字時鐘。
不過用Proteus仿真，
#include <reg51.h>

typedef unsigned char uint8;
typedef unsigned int uint16;
uint8 number[]={0x9e,0x24,
               0xc,0x98,0x48,
  0x40,0x1e,0x0,
  0x8};
uint8 numbera[]={0x79,0x24,0x30,
               0x19,0x12,0x2,
  0xf8,0x0,0x10,0x40
  };
uint8 numberb[]={0x79,0x24,0x30,
               0x19,0x12,0x2,
  0xf8,0x0,0x10,0x40
  };
uint8 numberc[]={0x79,0x24,0x30,
               0x19,0x12,0x2,
  0xf8,0x0,0x10,0x40
  };
main()
{
uint8 i,j,a,c;
uint16 counter;
P1=0x2;
P0=0x40;
P2=0x40;
P3=0x40;
TMOD=0x01;
TH0=0xb8;
TL0=0x00;
TR0=1;

while(1)
{

if (TF0==1)
{
   TH0=0xb8;
TL0=0x00;
TF0=0;
   counter++;
   }
  if(counter==1)
   {
counter=0;
   P1= number[i++];
}
if(i==10)
{ P1=0x2;
  i=0;
  P0=numbera[j++];
}
if(j==10)
  {
P0=0x40;
j=0;
P2=numberb[a++];
  }

  if(a==10)
  {
  a=0;
P3=numberc[c++];
  }
  if(c==10)
  {
   P3=0x40;
   c=0;
  }
}

}
