BNO055 Demo - Magnetic Calibration

This video is a demonstration of magnetic calibration of the BNO055 breakout board from Adafruit. I will show how to calibrate the sensor so it will display accurate magnetic direction after power up. The video will also show the process of calibrating the magnetometer.

The hardware used:

Arduino Mega
Adafruit 9DOF (BNO055)
Adafruit 2.8" TFT LCD w/ Capacitive Touch Shield and SD card
Adafruit Power Boost Shield
Mega Mini Shield (3D printed shield for mounting sensors)

Libraries:
Note, the BNO055 library from Adafruit was modified
to include calibration functions.
** Modified library MUST BE USED for this sketch to work **

Clarifications:

The TFT shield needs to be modified to work with the MEGA. The Mega and Leonardo need to use the ICSP header. Directions can be found on the Adafruit tutorial for this shield. See the Adafruit tutorial of the TFT Shield for more information.

An SD card in the TFT shield is used to save calibration values. Calibration values are read from the SD card and sent to the BNO055 at startup.
