8*8點(diǎn)陣流水顯示程序與原理

首先是讓漢字能夠靜態(tài)顯示，顯示一段時(shí)間后（時(shí)間可能很短）把所顯示的漢字編碼移一位重新送出，比如要向左移動(dòng)，原本顯示在第一列的數(shù)據(jù)就丟棄了，把第二列的數(shù)據(jù)送到第一列上顯示，依次移動(dòng)顯示一屏，顯示一段時(shí)間再進(jìn)行一次移動(dòng)，人們看起來(lái)也就是移動(dòng)的了。

這是程序：調(diào)試過(guò)的
硬件連接可以去這里：

#include
//sbit A=P2^0;
//sbit B=P2^1;
//sbit C=P2^2;
//sbit select=P2^3;

sbit clk=P3^0; //595串行時(shí)鐘端
sbit da=P3^1; //595串行數(shù)據(jù)端
sbit enable=P3^2;
