Compensation features of the BMM350 #4
Description
Hello,
I have read and ported the bmm350 driver code base to my platform.
The sensor at initialization reads the data from OTP, and than uses update_mag_off_sens(dev) to update coefficients for compensation, and after that bmm350GetCompensatedMagXYZTempData extracts the coefficients and then applies the compensation.
These compensations that are applied are
dut_offset_coef, dut_offset_coef, dut_tco, dut_tcs, dut_t0, and cross axis.
Where can I find more information on compensation of data from sensor bmm350 that explains these compensations.
Also, is the OTP updatable?
The datasheet refers to a Bosch Sensortec eCompass software but this software is also not found.
Best Regards,
Can
