how to use FFT on stm32f4xx series mcu?

I want to use FFT functionality on stm32f4xx mcu, so where can I find some guide document about this? Thanks!

CMSIS DSP would seem the obvious place to start

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.

Hi @xwang.3 ,

I suggest you to refer to X-CUBE-DSPDEMO: Digital Signal Processing with STM32, software expansion for STM32Cube (AN4841).

@xwang.3 and X-CUBE-DSPDEMO is based on CMSIS DSP

I wrote my own FFT/FHT routines. If you want to go down that path you might want to check out a previous post I wrote -
