3.11.4 Reuse of Calibration Profile
Once the device is calibrated, the calibration profile can be reused to get the correct
orientation data immediately after ‘Power of Reset’ (prior to going through the steps
mentioned in the above section). However, once the sensor enters the internal calibration
routine, the calibration profile is overwritten with the newly obtained sensor offsets and
sensor radius. Depending on the application, necessary steps had to be ensured for proper
calibration of the sensor.
Reading Calibration profile
The calibration profile includes sensor offsets and sensor radius. Host system can read the
offsets and radius only after a full calibration is achieved and the operation mode is switched
to CONFIG_MODE. Refer to sensor offsets and sensor radius registers.
Setting Calibration profile
It is important that the correct offsets and corresponding sensor radius are used. Incorrect
offsets may result in unreliable orientation data even at calibration accuracy level 3. To set
the calibration profile the following steps need to be taken
1. Select the operation mode to CONFIG_MODE
2. Write the corresponding sensor offsets and radius data
3. Change operation mode to fusion mode
