// Revised		: 2005/02/19
// Version		: 0.1
// Target MCU	: MEGA16
// Editor Tabs	: 4
//
//		sta013.h部分来自"Procyon AVRlib", 由Ant ([e-mail])修改测试.
//
// 注: 	本代码用于测试STA013硬件及其驱动程序, 并非一个完整的MP3播放器程序.
//		上电后,会循环不停播放一段约2秒的MP3音乐.
//		硬件没有连接RAM缓冲及储存MP3文件的设备, MP3数据是保存在AVR的FLASH中.
//		本代码经测试, 但可能存有Bugs, 若你发现有任何Bug或有任何建议,
//		请来信告知: [e-mail]
//
//		本代码部分来自"Procyon AVRlib": http://hubbard.engr.scu.edu/embedded/avr/avrlib/release_notes.html
//		特此感谢它的创始人: Pascal Stang !
