祥細視頻如下http://www.tudou.com/programs/view/D0SCJyO4RBQ/
完整的程序源代碼下載：http://www.51hei.com/f/dz854.rar
二、具體原理圖見
電路介紹：http://www.51hei.com/mcu/1523.html
三、具體程序代碼如下：
#include
#define uchar unsigned char
#define uint unsigned int
#define LINE P0//定義行線IO口，即74HC154控制端
#define shudu 12//字移動的速度
sbit DATA=P1^4;//74HC595數據端
sbit CLK=P1^5;//74HC595移位脈沖端
sbit CLKR=P1^6;//74HC595數據鎖存端
uchar move;//移動幾位變量
uchar line;//行變量
uint word;//字節變量
uchar ji,gai;//字節變量
uchar BUF[4];//4組緩存數組以便左移右移等功能動態更改數據
