calibrateMag(bbblue) calibrates the three-axis
magnetometer located inside the MPU-9250 sensor on the BeagleBone® Blue hardware, represented as bbblue. Use this function
before generating code from the MPU9250 block in DMP mode.
Create a connection to the BeagleBone Blue hardware. This connection reuses the IP address, user name, and
password from most recent connection to the BeagleBone Blue hardware. The resulting object, bbblue, represents
the BeagleBone Blue hardware. For more information on creating a connection to BeagleBone Blue hardware, see beagleboneblue.
bbblue = beagleboneblue
bbblue =
beagleboneblue with properties:
DeviceAddress: '172.69.7.2'
Port: 22
Use the calibrateMag function. Hold the hardware parallel to the
ground and rotate in the air through as many orientations as possible. The function
starts an internal calibration algorithm and then returns a message indicating the
status of the magnetometer calibration.
calibrateMag(bbblue)
Press ENTER to start calibrating the magnetometer.
Rotate the Beagleboneblue board in the air through as many orientation as possible. For more information, see Calibrate the Magnetometer in the MPU-9250 Sensor.
Magnetometer calibration in progress. Continue to rotate the board in the air.
Magnetometer calibration successful.
Note
During calibration, ensure that the hardware is stable and is far away from any
magnetic interference.
