基于STM32微控制器的MP3播放器设计

摘要

A design method of a music player is introduced in this paper,which is the MP3 player based on STM32 mi⁃cro controller of Cortex⁃M3 kernel that is designed specifically by ARM for the embedded applications of low cost,low power con⁃sumption and high performance. This system can realize the functions:playback of MP3 and WAV music file, and name dis⁃play of song,singer name and album.%介绍了一种音乐播放器的设计方法，该播放器是基于Cortex⁃M3内核的STM32微控制器的MP3播放器。Cor⁃tex⁃M3是ARM公司为要求低成本、低功耗、高性能的嵌入式应用专门设计的内核。结果表明该系统可以播放MP3和WAV音乐文件，播放同时显示歌曲名字，歌手和专辑名称。
