前言

本次任务：基于protues仿真实现at89c51控制16×16点阵led屏实现流水文字滚动，按键实现暂停，反向，调速需要用到的工具：keil5，protues8.9

提示：以下是本篇文章正文内容，下面案例可供参考

一、protues仿真安装软件

protues是一款仿真软件，推荐使用最新版protues8.9具体下载地址：protues8.9安装

绘制原理图

由于官方所给库中只有8×8点阵，现有两个方案：1自行绘制一个16×16点阵教程 2，用四块8×8点阵拼接而成（由于技术有限选择方案二）先点开元件库，在库里搜索我们需要的元件在这里插入图片描述接下来任选一个自己喜欢的颜色，同理选择at89c51芯片，74h138，按键，电阻电容等等。左上部分为51最小系统固定格式，照抄就好四块数码点阵图完整示例

二、keil程序编写 1.

代码如下（示例）：
