Hi, I don't know how to calibrate the soft iron magnetic field interference. I see the code `bno055_write_sic_matrix` and `bno055_read_sic_matrix`to configure the soft iron calibration matrix, but whenever I read the data in the sic matrix, it always: 0x4000 0x0000 0x0000 0x0000 0x4000 0x0000 0x0000 0x0000 0x4000, never change no matter how I move the sensor. It seems the real-time mag calibration couldn't calculate the sic matrix, which makes sense, it needs many data simples and the sensor may have no enough RAM. I know how to calculate the sic matrix but can I set the sic matrix myself with the API`bno055_write_sic_matrix`? How the 1 in the unit matrix is 0x4000? If it is 16 bits float, is the result should be 0 01111 0000000000=0x3C00? 0x4000 is 2 by my understand. Thanks! Kyle
