Question

谁能给我个51单片机的8*8流动显示LED的程序

想研究研究，求个程序，最好是能有字流动显示的，程序里最好有注释，要不理解太费劲了

这是我前几天写的：
#include "reg51.h"
#define uchar unsigned char
#define uint unsigned int
sbit SH_cp=P2^0;
sbit ST_cp=P2^1;
sbit DS=P2^2;

uchar code dis[22][8]={ {0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00}, //缓冲区

Answer 2

你是点阵吧？8*8是共阴还是共阳的呢？我这里有一些资料，需要可以来找我哈，随时都在线，等待回复。

追问

共阴共阳的能都给我点吗？

追答

好像只有共阴的。加1870111474吧，这里聊不太方便、。
