基于ATmega64L的MP3播放器设计

Design of MP3 Player Based on ATmega64L

设计了一款以U盘作存储介质的MP3文件播放系统。以ATmega64L为主控制器,音频解码芯片为VS1003B,CH375为U盘接口芯片,通过单片机控制实现对U盘的识别、文件的读取和处理。利用相应按键来控制歌曲的播放、选择、处理以及对音量、音效和循环模式进行设置,并把信息实时显示在液晶显示器上。实际使用表明,播放器可流畅播放U盘中的MP3文件,人机操作简便,功能较齐全,具有良好的应用前景。

This paper develops an MP3 player system using U disk storage media. The proposed system uses ATmega64L as a main controller, VS1003B as audio decoder chip, and CH375 as U disk interface chip, to achieve the recognition of U disk, reading and processing of MP3 files controlled by micropro- cessor. It may control the playing, selecting, volume, audio selection and cycle mode settings of songs by the corresponding keys. Moreover, the playing information can be displayed on the LCD monitor in real time. Practice shows that the designed player has the features of smooth playing, simple man-ma-chine interface, and complete functions with certain practical value.
