Vibration Calculation with ADXL345

[onerainywish]

Hello! Love the ADXL345 and I am trying to use the CircuitPython libraries to calculate vibration: https://github.com/adafruit/Adafruit_Ci ... n/examples

Running into some challenges, as I'm trying to calculate Hz, but don't see any examples of how to do this using CircuitPython library in Python. Can you please point me in the direction of some code samples that convert those x,y,z values sampled from the ADXL345 into Hz to show and measure vibration? Thanks!

To convert a series of values measured over time into frequencies usually requires either a Fourier transform or autocorrelation calculation. If you can't find examples for CircuitPython, there are several in C/C++ for Arduino.
