Python library for AW9523 GPIO expander and LED driver


Dependencies
=============
This driver depends on:

* `Adafruit CircuitPython <https://github.com/adafruit/circuitpython>`_
* `Bus Device <https://github.com/adafruit/Adafruit_CircuitPython_BusDevice>`_
* `Register <https://github.com/adafruit/Adafruit_CircuitPython_Register>`_

Please ensure all dependencies are available on the CircuitPython filesystem.
This is easily achieved by downloading
`the Adafruit library and driver bundle <https://circuitpython.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-circuitpython-aw9523/>`_. To install for current user:

.. code-block:: shell

    pip3 install adafruit-circuitpython-aw9523

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

.. code-block:: shell

    sudo pip3 install adafruit-circuitpython-aw9523

To install in a virtual environment in your current project:

.. code-block:: shell

    mkdir project-name && cd project-name
    python3 -m venv .venv
    source .venv/bin/activate
    pip3 install adafruit-circuitpython-aw9523

Usage Example
=============

.. code-block:: python

    import board
    import digitalio
    import adafruit_aw9523

    i2c = board.I2C()
    aw = adafruit_aw9523.AW9523(i2c)

    led_pin = aw.get_pin(0)  # LED on AW9523 io 0
    button_pin = aw.get_pin(1)  # Button on AW io 1

    # LED is an output, initialize to high
    led_pin.switch_to_output(value=True)
    # Button is an input, note internal pull-ups are not supported!
    button_pin.direction = digitalio.Direction.INPUT

    while True:
        # LED mirrors button pin
        led_pin.value = button_pin.value
