CircuitPython `displayio` driver for SSD1680-based ePaper displays
|
|
|
|
|
|
Dependencies
|
|
=============
|
|
This driver depends on:
|
|
|
|
* `Adafruit CircuitPython <https://github.com/adafruit/circuitpython>`_
|
|
|
|
Please ensure all dependencies are available on the CircuitPython filesystem.
|
|
This is easily achieved by downloading
|
|
`the Adafruit library and driver bundle <https://circuitpython.org/libraries>`_
|
|
or individual libraries can be installed using
|
|
`circup <https://github.com/adafruit/circup>`_.
|
|
|
|
* Adafruit 2.13" 250x122 Tri-Color eInk / ePaper Display with SRAM - SSD1680 Driver
|
|
|
|
`Purchase one from the Adafruit shop <http://www.adafruit.com/products/4947>`_
|
|
|
|
* Adafruit 2.13" HD Tri-Color eInk / ePaper Display FeatherWing - 250x122 RW Panel with SSD1680

Usage Example
|
|
=============
|
|
|
|
.. code-block:: python
|
|
|
|
import time
|
|
import board
|
|
import displayio
|
|
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 = displayio.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()
|
|
|
|
f = open("/display-ruler.bmp", "rb")
|
|
|
|
pic = displayio.OnDiskBitmap(f)
|
|
t = displayio.TileGrid(pic, pixel_shader=displayio.ColorConverter())
|
|
g.append(t)
|
|
|
|
display.show(g)
|
|
|
|
display.refresh()
|
|
|
|
print("refreshed")
|
|
|
|
time.sleep(120)
