我做的是八位数码管滚动显示学号
学号：1863400125
显示出来的数字不正确，查不出错误的地方
请各位大佬帮忙指出错误

单片机源程序如下:
#include <reg51.h>
#include <intrins.h>
#define uchar unsigned char
#define uint unsigned int
uchar code tab[] = {0x3f,0x06,0x5b,0x4f,0x66,0x6d,0x07,0x7f,0x6f};
uchar code number[] = {0,0,0,0,1,8,6,3,4,0,0,1,2,5};
uchar code wie[8] = {0x7f,0xbf,0xdf,0xef,0xf7,0xfb,0xfd,0xfe};
  //0xfe,0xfd,0xfb,0xf7,0xef,0xdf,0xbf,0x7f
uchar gg,aa,len;
void delay(uint x);
void main()
{
      while(1)
      {
            len=sizeof(number)/sizeof(uchar);
            for (gg=0;gg<len;gg++)
            {
                     for (aa=0;aa<30;aa++)
                     {
                              P2=wie[8];
                              P0=tab[number[gg]];
                              delay(5);

楼主仔细对比一下就明白错在哪。

#include <reg51.h>
#include <intrins.h>
#define uchar unsigned char
#define uint unsigned int
uchar code tab[ ]={0x3f,0x06,0x5b,0x4f,0x66,0x6d,0x7d,0x07,0x7f,0x6f,0x00};
uchar code wie[8]={0xfe,0xfd,0xfb,0xf7,0xef,0xdf,0xbf,0x7f};
uchar data number[]={10,10,10,10,1,8,6,3,4,0,0,1,2,5};
void delay(uint x);
void main()
{
uchar i,k,temp;
uint j;
while(1)
{
P0=0x00;
P2=wie[i];
P0=tab[number[i]];
i++;
i%=8;
j++;
if(j>=500)
{
j=0;
temp=number[0];
for(k=0;k<13;k++)
{
number[k]=number[k+1];
}
number[13]=temp;
}
delay(1);
}
}
void delay(uint x)
{
uint i,j;
for(i=x;i>0;i--)
for(j=120;j>0;j--);
}

uchar code tab[] = {0x3f,0x06,0x5b,0x4f,0x66,0x6d,0x07,0x7f,0x6f};原因是少了一个段码

仿真电路图能以图片形式发一下嘛
