Hello Community,
I am trying to implement a basic FFT computation on our STM32G0 MCUs using MotionSP for a 16-bit accelerometer signal.
I am not sure why does MotionSP by default uses float32 for FFT when the original sensor signal is 16-bit?
Can I then simply reconfigure the data type in the MotionSP by changing the float32 to q15?
Kindly guide, as we do not have FPU to compute float32.
Also, does a 16-bit sensor output requires a float32 FFT?
