采用C语言编写的MP3解码程序，可以移植到STM32等MCU，移植比较简单-mp3 audio file decoder source code,can use to a stm32 mcu

stm32 搭配芯片vs1003实现播放mp3，包括液晶等一般功能，代码函数写的不是很好，但是具有参考功能。-stm32 with chip vs1003 for playing mp3, including general functions such as liquid crystal, the code function was not very good, but with a reference function.
