BMI270 I2C Python library (bare bones)

BMI270 I2C Python Implementation - Version: 0.4.3

Bare bones BMI270 I2C Python implementation. This was a project for my practical phase at my University and my first time working hands on with IMUs.

Installation

The package is available on pypi.org.

You can install this package using this command:

pip3 install bmi270

For a Raspberry Pi Setup add/change this line in /boot/config.txt to your desired baudrate:

dtparam=i2c_baudrate=400000

Reboot your Raspberry Pi after applying the change.

Usage

Make sure these lines are connected: GND, 3V3, SDA, SCL

If you are using the SparkFun SPX-17353 BMI270 Breakout Board, you can easily connect them using a 1mm 4-pin JST connector cable. (example: Qwiic cables)

Make sure that the device is available at 0x68 or 0x69 i2c address by running this command:

i2cdetect -y 1

The BMI270 requires a config load. This initialization step is necessary to be able to use all its functions.

load_config()

A full power cycle is necessary if you want to load the config again.

Check out examples for more information.
