How to measure 200 samples/sec of accelerometer in pysense?

  • C

    I want to get 200 sample data in a seconds of x,y and z coordinates of accelerometer present in pysense board. I have set the output data rate of 200Hz (ODR value: 4). I am getting only on a average of 30 samples/sec from the acceleration function.
    Here i am attaching the LIS2HH12 setup code and main code to print the data in console.
