16*16点阵滚动显示制作出来的实物图如下：

仿真原理图如下（proteus仿真工程文件可到本帖附件中下载）

单片机源程序如下:

//宏定义
#define uchar unsigned char
#define uint unsigned int
#define zishu 10 //汉字数，两个字符是一个汉字，如果有单个字符，那么就加0.5
//包含头文件
#include <reg51.h>
#include <intrins.h>
//管脚定义
//154
sbit A_=P0^0; //74HC154的A
sbit B_=P0^1; //74HC154的B
sbit C_=P0^2; //74HC154的C
sbit D_=P0^3; //74HC154的D
sbit G2=P0^7; //74HC154的使能低电平有效
//595
sbit SI=P0^6;//数据脚
sbit SCK=P0^5;//上升沿时数据寄存器的数据移位。QA-->QB-->QC-->...-->QH；下降沿移位寄存器数据不变
sbit RCK=P0^4;//上升沿时移位寄存器的数据进入数据存储寄存器，下降沿时存储寄存器数据不变。通常我将
//RCK置为低电平，当移位结束后，在RCK端产生一个正脉冲（5V时，大于几十纳秒就行了。我
//通常都选微秒级），更新显示数据。
