今天看了下点阵的教程，自己跑去搞了下 ，结果弄是弄出来，可就是每次图像移动前都会红一团


  这是电路图还有代码，大大帮忙看看
#include<reg52.h>#define uchar unsigned char#define uint unsigned intsbit dula=P2^6;sbit wela=P2^7;sbit diola=P2^5;uint num,flag,num1;uchar code table[]={0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0x81,0xE7,0xE7,0xE7,0xE7,0xE7,0xE7,0x81,0xff,0x99,0x00,0x00,0x00,0x81,0xc3,0xe7,0x99,0x99,0x99,0x99,0x99,0x99,0x99,0xC3,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,};uchar code table1[]={0x01,0x02,0x04,0x08,0x10,0x20,0x40,0x80};void delay(uchar x){ uchar a,b; for(a=x;a>0;a--) for(b=110;b>0;b--);}void main(){   dula=1; wela=1; P0=0xff; dula=0; wela=0; while(1) { for(num=0;num<8;num++) { dula=1; P0=table[num+flag]; dula=0; P0=0;    diola=1; P0=table1[num]; diola=0; delay(5); P0=0xff; }     flag++; if(flag==40) flag=0; delay(200); }} 此帖出自小平头技术问答
