Magnetometer Soft Iron Matrix (0x0C,0x3B)

Description

Configure the user specified magnetometer soft iron offset matrix

Notes

The values for this matrix are determined empirically by external software algorithms based on calibration data taken after the device is installed in its application. These values can be obtained and set by using the LORD "MIP Iron Calibration" application. Alternatively, on some systems, the auto-mag calibration feature may be used to capture these values in-run. The matrix is applied to the scaled magnetometer vector prior to output.

The matrix is in row major order:
