標(biāo)題: 8*8點陣和數(shù)碼管顯示proteus仿真原理圖與單片機代碼
8*8點陣proteus仿真與數(shù)碼管原理圖如下：




單片機源程序：

  7. //此表為8個數(shù)碼管位選控制, 共陰數(shù)碼管 1-8個  -
  8. unsigned char code   dispbit[8]={0xfe,0xfd,0xfb,0xf7,0xef,0xdF,0xbF,0x7F};    //位選控制   查表的方法控制

  10. unsigned char led_buffer0[8]={0x01,0x03,0x07,0x0f,0x1f,0x3f,0x7f,0xff};

  12. unsigned char code led_buffer[]={
