This BNO055 absolute orientation sensor is just the thing I've been after for logging the hang-glider direction and heading. The way of lighting changes depending on the movement of the motion sensor. This was a success it works from start, has built in tilt compensating and calibration. Many of the higher performance commercially available pressure sensors are furnished with individual test data. Ideally, you would enter calibration mode just once (default at power-on), carefully go through the steps to calibrate the sensor (Datasheet page 47), and read the calibration data to store externally to non-volatile memory (EEPROM. Addendum 2016-03-05. I'm able to read the offsets and radius registers, then to save into the EEPROM of the ATmega328P and to load it afterwards. One thing that interests me is that the unit tends to lose calibration during certain kinds of motion. Unlike stepper motors, servomotors can be controlled with a single GPIO. I learned that this is a common problem for this sensor so if you are looking to use it for the Euler or Qauterion vectors don't get. Aortner 18 October 2019 11:40 #2. The BNO055 is three sensors in one device. This illustration shows the default orientation of the x-, y-, and z-axes of the BNO055 sensor.
