  apply rough calibration

  • calibrate_linear:

    retrieve these values by evaluating the raw values with loads of known mass.

    note that a bigger difference between measurements usually results in higher resolution,

    so measure 0 G and the highest known mass you have (like f.ex. your own weight, measured by a normal scale with good accuracy)

    • "-227236 -> 0"
    • "-120101 -> 530"

  map values below 0.1 to 0 (to decrease value changes due to random fluctuation)
