实验三 数码显示
一、实验目的
了解LED数码管动态显示的工作原理及编程方法。
二、实验内容
编制程序，使数码管显示“DJ--88”字样。
三、实验程序框图
四、实验步骤
联机模式：
（1）在PC机和实验系统联机状态下，运行该实验程序，可用鼠标左键单击菜单栏“文件”或工具栏“打开图标”，弹出“打开文件”的对话框，然后打开598K8ASM文件夹，点击S6.ASM文件，单击“确定”即可装入源文件，再单击工具栏中编译装载，即可完成源文件自动编译、装载目标代码功能，再单击“调试”中“连续运行”或工具图标运行，即开始运行程序。
（2）数码管显示“DJ--88”字样。
脱机模式：
1、在P.态下，按SCAL键，输入2DF0，按EXEC键。
2、数码管显示“DJ--88”字样。
