1、文理学院综合课程设计（一）Integrated Curriculum Design（1）所在院系信息工程系专业名称电子信息工程班级1001题目数字音乐盒设计指导教师成员完成时间2012.12.28 一、设计任务及要求：设计任务：设计一个数字音乐盒程序。要 求： 预写3个曲子可以实现播放/暂停、上一曲/下一曲功能有开机欢迎词，播放曲目时LCD屏幕上显示曲目名称指导教师签名： 2012年12月28日 二、指导教师评语：指导教师签名： 2012年12月 28 日 三、成绩 验收盖章 2012年12月28 日 数字音乐盒的设计1 设计目的（1）熟悉用于单片机C语言的一些用法。（2）掌握单片机的基本功能

2、。（3）了解程序是如何控制硬件。2 设计思路音乐部分用控制I/O口高低电平变化的快慢来改变发出音符的频率（即不同唱名的音）按键部分利用中断来控制播放/暂停、上曲/下曲功能3 设计过程 3.1方案论证该程序总体分为三个部分：音乐部分、按键部分、显示部分。音乐部分实现不用频率不同节拍的音构成完整曲目；按键部分实现播放/暂停（key1）、上曲/下曲功能；(key2/key3)显示部分实现开机问候语和曲目播放中曲名的显示；3.2程序设计音符部分：while(xuchar a)/此处uchar a填的数决定音符响的时长，uint b填的数决定音符频率 speaker=1; delayus(uint b)

3、; speaker=0; delayus(uint b)x=0;按键部分（播放/暂停）void keyscan()if(key1= =0)delayms(10);if(key1= =0)ET0=ET0;/通过控制中断开关ET0来实现播放暂停上一曲/下一曲 部分void T0_time()interrupt 1LCD部分程序(显示歌曲状态为暂停)while(1)if(key1= = 0)delayms(10);if (key1= =0) LCD部分程序break;void INT0_time()interrupt 0keyscan();按键部分（上曲/下曲）key1 部分if（key2= =0）

5、key3?NNYN曲 目 3 播 放/曲目3继续播放有键被按？曲3播完？NNkey1?暂停key1?key2?key3?NNYN4程序调试与结果分析4.1程序调试 在程序没有写完之前，如果前面声明了子函数，但是后面没有用到的话，会出现警告。只有程序写完整了警告才会不再出现；还有其中key=1和key= =1的意义不同，编译之后系统也判为警告，但实际上只能写作key= =1，写程序时应注意。4.2结果分析 在程序只完成了音乐部分和按键部分时（即没有加入显示部分时），用proteus仿真时反应速度较理想。在加入显示部分后，播放第一曲时按下“下一曲”键会过几秒才调到第二曲；播放曲目时按下“播放/暂停

6、”键大概超过半秒才会暂停，而从暂停到继续播放时快速点击按键即可。上述情况仍存在，但不影响音乐盒基本功能。5设计体会通过这次对数字音乐盒的设计与制作，我大概明白了设计一个具有一定功能的产品的部分基本步骤，了解到自己才刚起步，还有许多东西等着我去学习，我会在不断学习与实践中累积经验，向更高的目标迈进。参考文献(至少5篇)1新概念51单片机C语言教程（郭天祥著）2互联网3老师、同学的指导 附件完整程序（分段显示程序）#include#define uchar unsigned char#define uint unsigned intuchar code table=WELCOME;uchar co
