Respiration Rate using stm32f429i discovery kit

I am just working on vital sign monitor project.

I have a stm32f429i discovery kit.

We are using capacitive sensor for respiratory signals, its very weak signals.

Sensor output will be fed to adc of microcontroller.

Which we need to pass thr' fft and band pass filter.

does anyone have idea of using fft and band pass filter together for medical application?

thanks in advance

There is the DSP library for Cortex M, containing routines and example programs for FFT and filtering. There is at least one for the F40x, which is also be applicable to the F42x (never checked if there is one for the 42x, because I shun the ill-designed F429 discovery kit).

I am just working on vital sign monitor project.

I hope you have noticed the usual disclaimer at the last page of the MCU datasheet/reference manual:
