1、在“DLDP-MCU30单片机最小系统模块”上，将“EA”接“+5V”端。
2、使用排线将DLDP-MCU30单片机模块的P0、P1、P2、P3连接到DLDP-MCU27模块的L1、L9，H1，H9，编写实验程序并编译代码生成.HEX文件。
3、将.HEX文件下载至AT89S52单片机中。
4、观察实验现象，分析实验程序的正确性。

用点阵LED显示动态ห้องสมุดไป่ตู้形
实验
一、实验目的
掌握LED点阵显示的方法，深入了解显示的思路。
二、实验说明
LED点阵显示与LED数码显示原理基本相同，要用LED点阵显示组成图形或者字体需要不断的刷新点阵。
三、实验电路原理图
四、实验设备与器件
