一、硬件簡介：　經(jīng)過努力，終于完成了我以前一直的夢(mèng)想，點(diǎn)陣各種模式能獨(dú)立原創(chuàng)出點(diǎn)陣屏各種模式：間斷、上移、下移、左移、右移、上拉幕、下拉幕、左拉幕、右拉幕、左覆蓋、右覆蓋等等模式，我認(rèn)為點(diǎn)陣只要是上移、左移會(huì)了，基本其它的都會(huì)了！一定要理解了，才算喲，太高興了，現(xiàn)在和大家分享下了，我的硬件是：行是譯碼器74HC154＋S8550，列是74HC595移位寄存器.

祥細(xì)視頻如下http://www.tudou.com/programs/view/D0SCJyO4RBQ/

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(dòng)的速度

sbit DATA=P1^4;//74HC595數(shù)據(jù)端

sbit CLK=P1^5;//74HC595移位脈沖端

sbit CLKR=P1^6;//74HC595數(shù)據(jù)鎖存端

uchar move;//移動(dòng)幾位變量

uchar line;//行變量

uint word;//字節(jié)變量

uchar ji,gai;//字節(jié)變量

uchar BUF[4];//4組緩存數(shù)組以便左移右移等功能動(dòng)態(tài)更改數(shù)據(jù)
