Hello:

I have to do the FFT on a STM32L4 Nucleo32 board, but I don�t where to start. So any help will be welcomed.

Basically, I have an incoming sound signal, to which I have to do the FFT, but I don�t know how. I have read some information and I know that the are some Libraries to do the FFT.

Will I need a conditioning circuit before conecting to the board???

I�ve never had to do anything like this and I�m a bit lost.

Thank you : )

CMSIS includes some DSP stuff - like FFT.

Used to be available via the Standard Peripheral Libraries - so, presumably, now via the HAL ... ?

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.

And just sticking 'FFT on STM32L4' into google gives, as 2nd hit:
