八位数码管1到F动态滚动显示仿真原理图如下（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<reg51.h>
#define uchar unsigned char
#define uint unsigned int
uchar code DSY_CODE[]= { 0XC0,0XF9,0XA4,0XB0,0X99,0X92,0X82,0XF8,0x80,0x90,0x88,0x83,0xc6,0xa1,0x86,0x8e,
0XC0,0XF9,0XA4,0XB0,0X99,0X92,0X82,0XF8};
uchar code DSY_IDX[]={0X01,0X02,0X04,0X08,0X10,0X20,0X40,0X80}
void DelayMS(uint x)
uchar t;
while(x--)
for(t=0;t<120;t++);
}
void main(){
uchar i,j,u=8,k;
while(1){
u++;
j=u-8;
if(j==16)u=8;
if(j!=0&&j!=16)DelayMS(20);
for(i=0;i<20;i++)
for(k=0;j<u;j++,k++){
P0=0xff;
P0=DSY_CODE[j];
P2=DSY_IDX[k];
DelayMS(2);
}
j=u-8;
}
}
}
