As the attachment shows the option of magnetic calibration when using the NXP compass and the Freedom board with the Sensor Tool software, what calibration method is adopted by the Sensor Tool software? For example, the max-and-min calibration method, or the least square calibration method? Also, should I rotate the compass in a figure of eight? Or should I rotate the compass in the horizontal plane only? Or should I rotate the compass in the horizontal plane and one vertical plane?
Thank you very much,
