Convert MPU6050 raw data to frequency using python

Question

How to convert mpu6050 acceleration raw dato into frequency? i have followed some tutorials and in each and every solution , they calculate g values using raw data. Is there any solution to convert g values into frequency or convert raw values into frequency using pyton?

Answer 1

When you talk about frequency, as an analogy think about oscillations (like a pendulum). One oscillation cycle sees the pendulum change its direction of swing twice. When this direction changes, velocity changes from positive to negative or negative to positive.

If you integrate acceleration raw data, you get velocity. By tracking the velocity changing its sign (positive/negative), you can identify one oscillation cycle, thus its frequency.

If you are unsure how to do integral in code, this website's Arduino code shows how angular velocity is integrated to get angle and some acceleration raw data processing with MPU6050: https://www.instructables.com/How-to-Make-a-Robot-Car-Drive-Straight-and-Turn-Ex/
