Changing accelerometer sensing range

[ugemassolo]

Hi, I am looking for help to change the sensing range of the sensor. I would like to know what I should change for it to work correctly, since from what I understand, not only do you have to change the scaling factor but also the DATA_FORMAT. Thanks!

DATA_FORMAT is a register address (0x31) and should stay unchanged. DATA_FORMAT_B defines the measurement range and some other data formatting params:

You'll also need to update the accConversion accordingly.
