CircuitPython library for EPD e-ink displays.
Project description
Introduction
This library is for using CircuitPython with e-ink displays with built in SRAM.
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.
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-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 .env
source .env/bin/activate
pip3 install adafruit-circuitpython-epdUsage Example
import 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()Contributing
