display.refresh()

print("refreshed")

time.sleep(180)

We start by importing the libraries that we need. In this case we need time for adding delays, board the pin

definitions, and of course displayio .

import time

import board

import displayio

Next you want to uncomment the import statement for the correct driver for your display. This should match the file

you copied over earlier. In our case, the 2.9" uses the adafruit_il0373 driver, so we can leave it as is.

# Make sure your display driver is uncommented

import adafruit_il0373

#import adafruit_il91874

#import adafruit_ssd1608

#import adafruit_ssd1675

#import adafruit_il0398

Next we want to set these variables based on your display. If you have a flexible display, you would want to change

FLEXIBLE to True . If you have a monochrome display, you would want to change TRICOLOR to False . If you would

like to change the rotation, you can do that here as well.

# Set based on your display

FLEXIBLE = False

TRICOLOR = True

ROTATION = 90

Next we release any previously used displays. This is important because if the Feather is reset, the display pins are not

automatically released and this makes them available for use again.

displayio.release_displays()

Next we assign the Pins to use. Note that we are not using the SRAM on the eInk display, so we only need to connect

the SCK and MOSI SPI pins. We set the SPI object to the board's SPI with the easy shortcut function board.SPI() . We

also have the ePaper Display Chip Select and Data/Command pins.

For the breakout boards only, we define the Reset and Busy pins, otherwise you would change these to None in the

case of a shield or FeatherWing.

spi = board.SPI() # Uses SCK and MOSI

ecs = board.D9

dc = board.D10

rst = board.D5 # can be None to not use this pin

busy = board.D6 # can be None to not use this pin

In the next section, we set the highlight color to either red or black based on whether you have a monochrome or tri-
