Introduction
CircuitPython displayio
drivers for SSD1675-based ePaper displays
Dependencies
This driver depends on:
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:
pip3 install adafruit-circuitpython-ssd1675
To install system-wide (this may be required in some cases):
sudo pip3 install adafruit-circuitpython-ssd1675
To install in a virtual environment in your current project:
mkdir project-name && cd project-name
python3 -m venv .venv
source .venv/bin/activate
pip3 install adafruit-circuitpython-ssd1675
Usage Example
"""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
