1、基于单片机的音乐播放器的软件设计摘要本课题完成了基于STC89S52RC单片机为核心的音乐播放器的设计。经过对现有的多种方案的综合分析、比较，主要介绍了对U盘所存储的MP3、WMA格式经语音模块MP3-TF-16P的文件识别、提取以及音频解码程序实现的，通过与硬件调试表明所设计的音乐播放器可以通过按键选择歌曲以及控制音量，同时还可以通过LCD12894显示屏显示所播放的歌曲名。声音的播放可以通过扬声器进行，基本实现了音乐播放器的功能，并且通过显示屏和按键实现时间的显示和调节。关键词单片机；音乐播放器；U盘文件读取；音频解码MusicplayersoftwaredesignbasedonM
