MEMS (sensors)

I am currently working on an analog vibration sensor I have to recover 5 harmonics with my Stm32wle5jc I would like to know how to do a simple fft without DMA at first then with? because I am a beginner in the field

I tried to integrate an example of fft on my existing code and I have a problem "undefined reference to `arm_cfft_radix4_f32'" knowing that I just put the file arm_math.h and after I also tried to put the library DSP and lib arm_cortexM4lf_math.lib a...

Resolved! FP-IND-PREDMNT1 amplitude value of the FFT

I would like to know how is the amplitude of the FFT calculated by the FP-IND-PREDMNT1 firmware related to the acceleration measured by the accelerometer found on the STEVAL-STWINKT1 board. It is expressed in an absolute value but I need to know the ...

Limitation of Unicleo-GUI to represent FFT data

We have designed custom board which has STM32F446RE MCU and ISM330DLC vibration sensor.We are able to send FFT data with 512 sample to Unicleo-GUI and able to observe the FFT data for X,Y,Z axis on graph.But when we send FFT data with 1024 samples t...
