This library is for using CircuitPython with e-ink displays with built in SRAM.
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.
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-epdTo install system-wide (this may be required in some cases):
sudo pip3 install adafruit-circuitpython-epdTo 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-epdimport digitalio import busio import board from adafruit_epd.epd import Adafruit_EPD from adafruit_epd.il0373 import Adafruit_IL0373 # create the spi device and pins we will need spi = busio.SPI(board.SCK, MOSI=board.MOSI, MISO=board.MISO) ecs = digitalio.DigitalInOut(board.D12) dc = digitalio.DigitalInOut(board.D11) srcs = digitalio.DigitalInOut(board.D10) # can be None to use internal memory rst = digitalio.DigitalInOut(board.D9) # can be None to not use this pin busy = digitalio.DigitalInOut(board.D5) # can be None to not use this pin # give them all to our driver print("Creating display") display = Adafruit_IL0373(104, 212, spi, # 2.13" Tri-color display cs_pin=ecs, dc_pin=dc, sramcs_pin=srcs, rst_pin=rst, busy_pin=busy) display.rotation = 1 # clear the buffer print("Clear buffer") display.fill(Adafruit_EPD.WHITE) display.pixel(10, 100, Adafruit_EPD.BLACK) print("Draw Rectangles") display.fill_rect(5, 5, 10, 10, Adafruit_EPD.RED) display.rect(0, 0, 20, 30, Adafruit_EPD.BLACK) print("Draw lines") display.line(0, 0, display.width-1, display.height-1, Adafruit_EPD.BLACK) display.line(0, display.height-1, display.width-1, 0, Adafruit_EPD.RED) print("Draw text") display.text('hello world', 25, 10, Adafruit_EPD.BLACK) display.display()API documentation for this library can be found on Read the Docs.
