# 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](https://pypi.org/project/bmi270).
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](https://github.com/CoRoLab-Berlin/bmi270_python/tree/main/examples) for more information.
## Tested with:
- Ubuntu 22.04.2 LTS
- Raspbian 10 - Buster (32 Bit)
## Dependencies
**requires Python >= 3.7**
**[smbus2](https://github.com/kplindegaard/smbus2)** *(auto installed)*
Manual installation:
`pip3 install smbus2`
## Functionality
- BMI270 class integration
- load config file into BMI270
- write/read registers
- a few other functions (see [BMI270.py](https://github.com/CoRoLab-Berlin/bmi270_python/blob/main/src/bmi270/BMI270.py))

## Troubleshooting
-bash: pip3: command not found
`sudo apt install python3-pip`
