CircuitPython displayio drivers for IL0398 driven e-paper displays


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


This library is not available on PyPI yet. Install documentation is included as a standard element. Stay tuned for PyPI availability!

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-il0398

To install system-wide (this may be required in some cases):

sudo pip3 install adafruit-circuitpython-il0398

To install in a virtual environment in your current project:

mkdir project-name && cd project-name
python3 -m venv .env
source .env/bin/activate
pip3 install adafruit-circuitpython-il0398

Usage Example

"""Simple test script for 4.2" 400x300 black and white displays.

Supported products:
  * WaveShare 4.2" Black and White

import time
import board
import displayio
import adafruit_il0398


# This pinout works on a Feather M4 and may need to be altered for other boards.
spi = board.SPI() # Uses SCK and MOSI
epd_cs = board.D9
epd_dc = board.D10
epd_reset = board.D5
epd_busy = board.D6

display_bus = displayio.FourWire(spi, command=epd_dc, chip_select=epd_cs, reset=epd_reset,

display = adafruit_il0398.IL0398(display_bus, width=400, height=300, seconds_per_frame=20,

g = displayio.Group()

f = open("/display-ruler.bmp", "rb")

pic = displayio.OnDiskBitmap(f)
t = displayio.TileGrid(pic, pixel_shader=displayio.ColorConverter())
