Where are the CMSIS-DSP libraries for STM32U5A9J

nico23 · ‎2025-12-30

So I have a board which I'm correctly using with threadX and TouchGFX.

I want to implement a function that calculates the FFT of a signal, but I'm having a hard time finding the CMSIS-DSP libraries.

I need to include the classic math library for ARM

#include "arm_math.h"
#include "arm_const_structs.h"

But in cubeMX I'm finding various DSP libraries

what should I use?

Does this help: How to integrate CMSIS-DSP libraries on a STM32 project ?

Also: Configuring DSP libraries on STM32CubeIDE ?

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.
