本例是基于STM32F407完成对。本代码主要完成MP3播放，界面显示等功能，还可在此基础上外扩点阵屏实现LED显示功能！(This case is based on the completion of the STM32F407. The code is mainly to complete MP3 playback, interface display and other functions, can also be based on the expansion of LED dot matrix screen display function!)

单片机工程应用中，开机时跑马灯代码，实现五个led的顺序闪烁，可实现运行提示功能(Marquee code)

求路面功率谱,根据加速度功率谱求路面功率谱密度函数(power spectrum)
