標(biāo)題: 八位數(shù)碼管滾動(dòng)顯示學(xué)號(hào)，請(qǐng)各位大佬來看看我的單片機(jī)程序錯(cuò)在哪里

我做的是八位數(shù)碼管滾動(dòng)顯示學(xué)號(hào)
學(xué)號(hào)：1863400125
顯示出來的數(shù)字不正確，查不出錯(cuò)誤的地方
請(qǐng)各位大佬幫忙指出錯(cuò)誤

單片機(jī)源程序如下:

仿真電路圖

樓主仔細(xì)對(duì)比一下就明白錯(cuò)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;

復(fù)制代碼

uchar code tab[] = {0x3f,0x06,0x5b,0x4f,0x66,0x6d,0x07,0x7f,0x6f};原因是少了一個(gè)段碼

仿真電路圖能以圖片形式發(fā)一下嘛
