标题: 电子时钟仿真与单片机编程
电子时钟仿真原理图如下（proteus仿真工程文件可到本帖附件中下载）




单片机源程序如下:
  1. //LED6CC_CLOCK
  2. #include <AT89X52.H>
  3. unsigned char code dispcode[]={0x3f,0x06,0x5b,0x4f,0x66,0x6d,0x7d,0x07,
  4.                                                         0x7f,0x6f,0x77,0x7c,0x39,0x5e,0x79,0x71,0x00};
  5. unsigned char dispbitcode[]={0xfe,0xfd,0xfb,0xf7,0xef,0xdf};
  6. unsigned char dispbuf[6]={0,0,0,0,2,1};
  7. unsigned char dispbitcnt;
  8. unsigned char second;
  9. unsigned char minite;
  10. unsigned char hour;
  11. unsigned int tcnt;
  12. unsigned char mstcnt;
  13. unsigned char i,j;
  14. void delay()
  15. {
  16. unsigned char i,j;

  19. }

  59. while(P0_1==0);
  60. }
  61. }

  63. {
  64. delay();

  66. {
  67. hour++;
  68. if(hour==24)
  69. {
  70. hour=0;
  71. }
  72. dispbuf[4]=hour%10;
  73. dispbuf[5]=hour/10;
  74. while(P0_2==0);
  75. }
  76. }
  77. }
  78. }
  79. void t0(void) interrupt 1

  87. P3=0xff; //关闭所有显示
  88. P3=dispbitcode[dispbitcnt];//

  90. dispbitcnt++;
