Helper Library for Blinka to allow creating I2C and SPI busio objects by passing in the Bus ID. This library is not compatible with CircuitPython and is intended to only be run on Linux devices.

Dependencies

This driver depends on:

• Adafruit Python <https://github.com/adafruit/Python>_

Please ensure all dependencies are available on the Python filesystem. This is easily achieved by downloading the Adafruit library and driver bundle <https://Python.org/libraries>_.

Installing from PyPI

On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally from PyPI <https://pypi.org/project/adafruit-extended_bus/>_. To install for current user:

.. code-block:: shell

pip3 install adafruit-extended-bus

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

.. code-block:: shell

sudo pip3 install adafruit-extended-bus

To install in a virtual environment in your current project:

.. code-block:: shell

mkdir project-name && cd project-name
python3 -m venv .env
source .env/bin/activate
pip3 install adafruit-extended-bus

Usage Example

.. code-block:: python

from adafruit_extended_bus import ExtendedI2C as I2C
import adafruit_bme280

# Create library object using our Extended Bus I2C port
i2c = I2C(1) # Device is /dev/i2c-1
bme280 = adafruit_bme280.Adafruit_BME280_I2C(i2c)
print("\nTemperature: %0.1f C" % bme280.temperature)
