CircuitPython displayio driver for IL0373-based ePaper 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-il0373/>_. To install for current user:

.. code-block:: shell

pip3 install adafruit-circuitpython-il0373

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

.. code-block:: shell

sudo pip3 install adafruit-circuitpython-il0373

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-il0373

Usage Example

.. code-block: python

"""Simple test script for 2.13" 212x104 tri-color featherwing.

Supported products:
  * Adafruit 2.13" Tri-Color FeatherWing
    * https://www.adafruit.com/product/4128
