BMI260/BMI270 I2C Python library (bare bones)

BMI260/BMI270 I2C Python Implementation - Version: 0.4.5

Bare bones BMI260/BMI270 I2C Python implementation. This was a project for my practical phase at my University and my first time working hands on with IMUs.

Fork

• Added BMI260 support

Installation

The package is available on pypi.org.

You can install this package using this command:

pip3 install bmi260

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.

Tested with:

• Ubuntu 22.04.2 LTS
• Raspbian 10 - Buster (32 Bit)

Dependencies

requires Python >= 3.7

smbus2 (auto installed)

Manual installation: pip3 install smbus2

Functionality

• BMI270 class integration
• load config file into BMI270/BMI260
• write/read registers
• a few other functions (see BMI270.py)
