智能仪表课程设计与制作实训项目之二

简易WAVE音乐播放器

一、设计要求
用单片机设计并制作一个可以播放WAVE格式的音乐播放器。要求：
1.在单片机内部内置4首WAVE格式音乐；
2.用4个不同按键代表播放不同的音乐，当某个音乐播放的时候，按其他音乐按键没有任何效果；
3.当音乐开始播放后，按停止按键可以终止当前的音乐播放；
4.在音乐播放的同时，用8个LED灯表示音乐播放的音节。
二、电路原理
音节显示LED电路原理可参考图1-1。

图1-1 音节显示LED原理图
音乐播放部分电路图可以参考图1-2。

图1-2 音乐播放部分电路参考原理图
按键部分电路图可以参考图1-3。

图1-3 按键部分电路参考原理图
核心部分原理图可以参考图1-4。

图1-4 核心部分原理图
电路也可自行设计。
三、程序的设计
