    BMM150 Z axis data

    BMM150 Z axis data

    Hi,

    How can I get Z axis data in range of ±2500uT and LSB=1/16uT with 16 bits sample from the driver?

    The problem is:

    1/16uT means 4 bits of data

    +/-2500uT means 13 bits of data

    So total of 17 bits. From the IC register I get only 15 bits, and from the driver (The Z compensation function) I only get 16 bits...

    How should I interpret the result from the driver function?

    Thanks,

    Kobi

    Re: BMM150 Z axis data

    Hi Kobi,

    With the integer compensation functions, the maximum number that can be expressed due to the scaling factor is +/- 2048uT.

    For the full range of the sensor, please enable the floating point calculations:
