喜歡的可以下載
仿真原理圖如下（proteus仿真工程文件可到本帖附件中下載）


單片機(jī)源程序如下:
  1. #include <reg52.h>
  2. #include <intrins.h>
  3. #define uchar unsigned char
  4. #define uint unsigned int
  5. uchar code Table_OF_Digits[]=
  6. {
  7.         0x00,0x3e,0x41,0x41,0x41,0x3e,0x00,0x00,
  8.         0x00,0x00,0x00,0x21,0x7f,0x01,0x00,0x00,
  9.         0x00,0x27,0x45,0x45,0x45,0x39,0x00,0x00,
  10.         0x00,0x22,0x49,0x49,0x49,0x36,0x00,0x00,
  11.         0x00,0x0c,0x14,0x24,0x7f,0x04,0x00,0x00,
  12.         0x00,0x72,0x51,0x51,0x51,0x4e,0x00,0x00,
  13.         0x00,0x3e,0x49,0x49,0x49,0x26,0x00,0x00,
  14.         0x00,0x40,0x40,0x40,0x4f,0x70,0x00,0x00,
  15.         0x00,0x36,0x49,0x49,0x49,0x36,0x00,0x00,
  16.         0x00,0x32,0x49,0x49,0x49,0x3e,0x00,0x00,
  17. };
  18. uchar i=0,t=0,Num_Index = 0;

  20. void main()
  21. {
  22.         P3 = 0x80;
  23.         Num_Index = 0;
  24.         TMOD = 0x00;
  25.         TH0 = (8192-2000)/32;
  26.         TL0 = (8192-2000)%32;
  27.         TR0 = 1;
  28.         IE = 0x82;
  29.         while(1);
  30. }

  32. void LED_Screen_Display() interrupt 1
  33. {
  34.         TH0 = (8192-2000)/32;
  35.         TL0 = (8192-2000)%32;
  36.         P3 = _crol_(P3,1);
  37.         P0 = ~Table_OF_Digits[Num_Index * 8 +i];
  38.         if(++i == 8) i = 0;
  39.         if(++t == 250)
  40.         {
  41.                  t = 0x00;
  42.                 if(++Num_Index == 10) Num_Index = 0;
  43.         }
  44. }
