Introduction
CircuitPython displayio driver for SSD1681-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 or individual libraries can be installed using circup.
Adafruit 1.54” Tri-Color eInk / ePaper 200x200 Display with SRAM
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-ssd1681To install system-wide (this may be required in some cases):
sudo pip3 install adafruit-circuitpython-ssd1681To 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-ssd1681Usage Example
import time
import board
import displayio
import fourwire
import adafruit_ssd1681
displayio.release_displays()
# 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 = fourwire.FourWire(
spi, command=epd_dc, chip_select=epd_cs, reset=epd_reset, baudrate=1000000
)
time.sleep(1)
display = adafruit_ssd1681.SSD1681(
display_bus, width=200, height=200, busy_pin=epd_busy, rotation=180
)
g = displayio.Group()
pic = displayio.OnDiskBitmap("/display-ruler.bmp")
t = displayio.TileGrid(pic, pixel_shader=pic.pixel_shader)
g.append(t)
display.root_group = g
display.refresh()
print("refreshed")
