adafruit-circuitpython-ssd1680 1.2.4

Introduction

CircuitPython displayio driver for SSD1680-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 or individual libraries can be installed using circup.

• Adafruit 2.13” 250x122 Tri-Color eInk / ePaper Display with SRAM - SSD1680 Driver

Purchase the Breakout from the Adafruit shop

• Adafruit 2.13” HD Tri-Color eInk / ePaper Display FeatherWing - 250x122 RW Panel with SSD1680

Purchase the FeatherWing from the Adafruit shop

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-ssd1680

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

sudo pip3 install adafruit-circuitpython-ssd1680

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-ssd1680

Usage Example

import time
import board
import displayio
import fourwire
import adafruit_ssd1680

displayio.release_displays()

# This pinout works on a Metro 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.D8    # Set to None for FeatherWing
epd_busy = board.D7    # Set to None for FeatherWing

display_bus = fourwire.FourWire(
    spi, command=epd_dc, chip_select=epd_cs, reset=epd_reset, baudrate=1000000
)
time.sleep(1)

display = adafruit_ssd1680.SSD1680(
    display_bus,
    width=250,
    height=122,
    busy_pin=epd_busy,
    highlight_color=0xFF0000,
    rotation=270,
)

g = displayio.Group()

# CircuitPython 6 & 7 compatible
f = open("/display-ruler.bmp", "rb")
pic = displayio.OnDiskBitmap(f)
t = displayio.TileGrid(
    pic, pixel_shader=getattr(pic, "pixel_shader", displayio.ColorConverter())
)

# # CircuitPython 7 compatible only
# 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")

time.sleep(120)
