Simple webservice for Adafruit BNO08x IMU on Raspberry Pi i2c interface. IMU Inertial measurement unit.
Details of the BNO08x can be found here https://learn.adafruit.com/adafruit-9-dof-orientation-imu-fusion-breakout-bno085/overview
Python env created with
python3 -m venv envActivate the env with
source env/bin/activate
Add web.py and the circuit python library for the board
pip3 install web.py
sudo pip3 install adafruit-circuitpython-bno08xSetting up the PI, works best setting the i2c baud rate to 400kHz, by adding to the /boot/config.txt file and rebooting the pi
dtparam=i2c_arm_baudrate=400000To run
./imu_webservice.py
