標題: 51單片機74ls595控制16*32點陣屏顯示走字屏，附帶源碼以及Proteus仿真
仿真原理圖如下（proteus仿真工程文件可到本帖附件中下載）

單片機源程序如下:
#include <reg51.h>
#define uchar unsigned char
#define uint unsigned int

sbit SRCLK=P2^0;//hang
sbit RCLK=P2^1;
sbit SER=P2^2;

sbit SRCLK2=P0^0;//lie
sbit RCLK2=P0^1;
sbit SER2=P0^2;

//字模格式 16x16  陰碼，逐行，逆向，十六進制，C51格式

可以問下您怎么換個方向顯示和加快滾動嗎
