CircuitPython `displayio` driver for IL91874-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-il91874/>`_. To install for current user:
.. code-block:: shell
pip3 install adafruit-circuitpython-il91874
To install system-wide (this may be required in some cases):
.. code-block:: shell
sudo pip3 install adafruit-circuitpython-il91874
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-il91874
Usage Example
=============
.. code-block:: python
"""Simple test script for 2.7" 264x176 Tri-Color display shield
Supported products:
* Adafruit 2.7" Tri-Color ePaper Display Shield
* https://www.adafruit.com/product/4229

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
display.refresh()
print("refreshed")
