制作出來的實物圖如下：

單片機源程序如下:
#include<stc15.h>
#include "intrins.h"
#define uchar unsigned char
#define uint unsigned int
#define s1_s0 0x40
#define s1_s1 0x80
#define led P1
uchar receive_data;
void UartInit (void)
{
      ACC=P_SW1;
      ACC &=(s1_s0|s1_s1);
      ACC |=s1_s0;
      P_SW1=ACC;
      SCON=0x50;
      AUXR|=0x01;
      AUXR|=0x04;
      T2L=0xe0;
      T2H=0xfe;
      ES=1;
      EA=1;
}
void main()
{
      UartInit();
      while(1)
      {
            switch(receive_data)
            {
                     case 0: led=0xff;       break;
                     case 1: led=0xfe;       break;
                     case 2: led=0xfc;       break;
                     case 3: led=0xf8;       break;
                     case 4: led=0xf0;       break;
                     case 5: led=0xe0;       break;
                     case 6: led=0xc0;       break;
                     case 7: led=0x80;       break;
                     case 8: led=0x00;       break;
            //       default: led=0xff: break;
            }
      }
}

void com_Int(void) interrupt 0
{
      EA=0;
      if(RI==1)
      {
            RI=0;
            receive_data=SBUF-0X30;
      }
      SBUF=receive_data+0x30;
      while(!TI)
            TI=0;
            EA=1;
}
