第二十八课 点阵之四 流动字符

相信如果大家对以前的内容理解的比较好的话，现在的程序对大家来说是轻而易举的了
程序讲解：
/*--------------------------------------------------------------*/
//LED8*8滚动显示

/*--------------------------------------------------------------*/
//包含头文件
#include <reg52.h>
#include "74HC595.H"       //第九课有详细讲解

/*--------------------------------------------------------------*/
//代码库 可用软件取（上节课有下载链接）
#define  num  sizeof(table) //代码长度 还记得 sizeof(table)吗？前面几节课的内容
unsigned char code table[]= {
