CREG_MAG_CAL1_1 to CREG_MAG_CAL3_3 – 0x0F (15) to 0x17 (23)

SUMMARY

These registers store the 9 entries into a 3x3 matrix that is used to perform soft-iron calibration

of the magnetometer on the device. These terms can be computed by performing

magnetometer calibration with the CHR Serial Interface.

32-bit IEEE Floating Point Value

CREG_MAG_BIAS_X – 0x18 (24)

SUMMARY

This registers stores a bias term for the magnetometer x-axis for hard-iron calibration. This

term can be computed by performing magnetometer calibration with the CHR Serial Interface.

32-bit IEEE Floating Point Value

CREG_MAG_BIAS_Y – 0x19 (25)

SUMMARY

This registers stores a bias term for the magnetometer y-axis for hard-iron calibration. This

term can be computed by performing magnetometer calibration with the CHR Serial Interface.

32-bit IEEE Floating Point Value

CREG_MAG_BIAS_Z – 0x1A (26)
