这是8位数码管静态显示20110230，请求各位大神：如何让数字依次向左滚动，把所有的数字（2011023011）都显示出来，真心希望大神在下面的程序上改一下，急需！！谢谢！！！
#include <reg52.h>
#define uchar unsigned char
      
uchar xuehao[] = {2 , 0, 1 , 1 , 0 , 2 , 3, 0} ;

for (i = 0 ; i < 100 ; i ++) ;
}

while (1)

  for (i = 0 ; i < 8 ; i ++)
  {
   P0 = ledcode[xuehao[i]];
   P2 = ledseg[i] ;
   Delay () ;
   P2 = 0xff ;
  }
}
