    BMX160 Mag Data ajustment

    BMX160 Mag Data ajustment

    Hi, 

    I would like to know how to ajust the Mag Data out of a BMX160 device. After ajusting the accel. and gyro data with the appropriate conversions from LSB units, I don't find any conversions for the mag data. I linked pictures of what I get, which turns around 100 for z and around -30 for x and y. 

    Am I right to be expecting something around 50 in an axis (earth's magnetic field) and close to 0 for the 2 remaining axis ?

    Thanks for your help!

    BMX160 has built in BMM150 inside sensor. 

    So you can refer to the BMM150 API on Github with function: "bmm150_aux_mag_data". 

    Within this funciton,  you can find how to convert the register output to uT. 

    This solution is accurate. 

    I would add that we should follow the advice at the end of this topic to get the correct z values. 

    Thank you !
