流水控制LED及音乐播放

1、西安科技大学大学生业余制作报告 学院： 班级： 学号： 姓名： 内 容 摘 要 电子技术实验是一门重要的实践性技术基础课程。开设本课程的目的在于使学生理论联系实际，在老师的指导下完成大纲规定的实验任务。通过实验熟悉电工.电子技术的应用中常用的设备和电子器件，熟悉常用仪器的使用方法，掌握正确记录.处理实验数据、绘制曲线、分析实验结果的方法，从而开发学生分析问题或解决问题的能力，培养学生具有严谨的工作作风，实事求是的科学态度，刻苦钻研、勇于探索和创新的开拓精神以及遵守纪律、团结协作和爱护公物的优良品质，为今后从事专业科研工作和工程技术工作打下良好的基础。流水灯是一串按一定的规律像流水一样连续闪亮。

2、流水灯控制是可编程控制器的一个应用，其控制思想在工业控制技术领域也同样适用。索引关键词：流水灯 循环亮灭一 设计目的 进一步熟悉keil仿真软件、伟福仿真器和实验板的使用。了解并熟悉实验板上单片机I/O口和LED灯的电路结构，掌握C51中单片机I/O口的编程方法，掌握顺序控制程序的简单编程。二 设计内容电路开启后：led灯先是上面4个亮上面4个灭，然后下面4个亮下面4个灭 ，接着中间向两边依次拓展亮这样为一个循环，循环6次之后2,4,6,8灯亮并播放音乐。三程序设计原理当8255 的PA口有低电平输出时，相应的发光二极管就会点亮。应用这一原理我们可以容易的点亮一个数码管，例如令PA口输出011

3、1 1111时D1就会点亮。若再把0111 1111向右循环一位，利用PA口输出，就会点亮D2。在发光二极管两次点亮的间隔中加延时程序，让每次点亮停留一段时间，像这样人眼就可以看到“流水” 的现象。四 程序流程图初始化开始执行流水灯一次循环是判断循环次数是否小于5次否播放音乐五源程序#include <reg51.h>#include<intrins.h>#define LED P0typedef unsigned uchar;typedef unsigned uint;sbit LED1 = P00;sbit LED2 = P01;sbit LED3 = P02;sb
