CircuitPython `displayio` drivers for SSD1675-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-ssd1675/>`_. To install for current user:
.. code-block:: shell
pip3 install adafruit-circuitpython-ssd1675
To install system-wide (this may be required in some cases):
.. code-block:: shell
sudo pip3 install adafruit-circuitpython-ssd1675
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-ssd1675
Usage Example
=============
.. code-block:: python
"""Simple test script for 2.13" 250x122 black and white featherwing.
Supported products:
* Adafruit 2.13" Black and White FeatherWing
* https://www.adafruit.com/product/4195
