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 : )
