//--------------------------- 实验程序名称：MP3播放器 ------------------------------
//
//开发平台：ATmega16教学实验板
//外设使用：1. T/C0定时器  2. AD模数转换（通道7）   3. SPI总线
//模块使用：1.AD键盘   2.SD卡   3.VS1003模块
//频率：外频16MHz
//电压：3.3V
//
//存储体：SD卡
//文件系统：FAT32
//显示器：不带
//音乐文件：SD卡上命名“音乐”文件夹，在“音乐”文件夹内存储歌曲，格式为“MP3“。
//按键操作： |  Key6  |  Key5  |   Key4  |  Key3  |  Key2  |  Key1  |
//           |  播放  |  停止  |  上一首 |  音量+ |  音量- | 下一首 |
//
//原理：使用ATmega16读取SD卡中音乐文件传输到VS1003进行解码播放。
//重点：1.文件系统  2.SD卡驱动
//
