|
CircuitPython `displayio` driver for SSD1608-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-ssd1608/>`_. To install for current user:
|
|
|
|
.. code-block:: shell
|
|
|
|
pip3 install adafruit-circuitpython-ssd1608
|
|
|
|
To install system-wide (this may be required in some cases):
|
|
|
|
.. code-block:: shell
|
|
|
|
sudo pip3 install adafruit-circuitpython-ssd1608
|
|
|
|
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-ssd1608
|
|
|
|
Usage Example
|
|
=============
|
|
|
|
.. code-block:: python
|
|
|
|
"""Simple test script for 1.54" 200x200 monochrome display.
|
|
|
|
Supported products:
|
|
* Adafruit 1.54" Monochrome ePaper Display Breakout
|
|
* https://www.adafruit.com/product/4196
