Introduction

CircuitPython displayio drivers for SSD1675-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:

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
