CircuitPython `displayio` driver for IL0373-based ePaper displays

Dependencies

=============

This driver depends on:

* `Adafruit CircuitPython `_

Please ensure all dependencies are available on the CircuitPython filesystem.

This is easily achieved by downloading

`the Adafruit library and driver bundle `_.

Installing from PyPI

=====================

On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally `from

PyPI `_. 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

      """

    import time

    import board

    import displayio

    import fourwire

    import adafruit_il0373

    displayio.release_displays()

    epd_cs = board.D9

    epd_dc = board.D10

    display_bus = fourwire.FourWire(board.SPI(), command=epd_dc, chip_select=epd_cs, baudrate=1000000)

    time.sleep(1)

    display = adafruit_il0373.IL0373(display_bus, width=212, height=104, rotation=90,

                                     highlight_color=0xff0000)

    g = displayio.Group()

    f = open("/display-ruler.bmp", "rb")

    pic = displayio.OnDiskBitmap(f)

    # CircuitPython 6 & 7 compatible

    t = displayio.TileGrid(

        pic, pixel_shader=getattr(pic, "pixel_shader", displayio.ColorConverter())

    )

    # CircuitPython 7 compatible only

    # t = displayio.TileGrid(pic, pixel_shader=pic.pixel_shader)

    g.append(t)

    display.root_group = g
