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:
- #include<reg52.h>
- unsigned int a,b,c;
- unsigned char code tab[]={0xfe,0xfd,0xfb,0xf7,
- 0xef,0xdf,0xbf,0x7f};
- unsigned char code tab1[10][8]={
- {0x00,0x00,0x3e,0x41,0x41,0x41,0x3e,0x00}, //0
- {0x00,0x00,0x00,0x00,0x21,0x7f,0x01,0x00}, //1
- {0x00,0x00,0x27,0x45,0x45,0x45,0x39,0x00}, //2
- {0x00,0x00,0x22,0x49,0x49,0x49,0x36,0x00}, //3
