This driver depends on the Register and Bus Device libraries. Please ensure they are also available on the CircuitPython filesystem. This is easily achieved by downloading a library and driver bundle.

On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally from PyPI. To install for current user:

pip3 install adafruit-circuitpython-bno055

To install system-wide (this may be required in some cases):

sudo pip3 install adafruit-circuitpython-bno055

To install in a virtual environment in your current project:

mkdir project-name && cd project-name
python3 -m venv .venv
source .venv/bin/activate
pip3 install adafruit-circuitpython-bno055

Of course, you must import the library to use it:

import adafruit_bno055

This driver takes an instantiated and active I2C object as an argument to its constructor. The way to create an I2C object depends on the board you are using. For boards with labeled SCL and SDA pins, you can:

import board
i2c = board.I2C()

Once you have the I2C object, you can create the sensor object:

sensor = adafruit_bno055.BNO055_I2C(i2c)

And then you can start reading the measurements:

print(sensor.temperature)
print(sensor.euler)
print(sensor.gravity)

API documentation for this library can be found on Read the Docs.
