CircuitPython displayio drivers for IL0398 driven e-paper displays


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

* `Adafruit CircuitPython <https://github.com/adafruit/circuitpython>`_

Please ensure all dependencies are available on the CircuitPython filesystem.
This is easily achieved by downloading
`the Adafruit library and driver bundle <https://github.com/adafruit/Adafruit_CircuitPython_Bundle>`_.

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-il0398/>`_. To install for current user:

.. code-block:: shell

    pip3 install adafruit-circuitpython-il0398

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

.. code-block:: shell

    sudo pip3 install adafruit-circuitpython-il0398

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-circuitpython-il0398

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

.. code-block:: python

    """Simple test script for 4.2" 400x300 black and white displays.

    Supported products:
      * WaveShare 4.2" Black and White
        * https://www.waveshare.com/product/modules/oleds-lcds/e-paper/4.2inch-e-paper.htm
        * https://www.waveshare.com/product/modules/oleds-lcds/e-paper/4.2inch-e-paper-module.htm
