CircuitPython `displayio` driver for epaper driven by UC8253 driver IC
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>`_.
* `3.7" 416x240 Monochrome Black/White eInk / ePaper - Bare Display - UC8253 Chipset <https://www.adafruit.com/product/6395>`_
* `3.7" 416x240 Tri-Color Red / Black / White eInk - Bare Display - UC8253 Chipset <https://www.adafruit.com/product/6394>`_
`Purchase one from the Adafruit shop <http://www.adafruit.com/products/>`_
Installing from PyPI
=====================
On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally `from
PyPI <https://pypi.org/project/adafruit-circuitpython-uc8253/>`_.
To install for current user:
.. code-block:: shell
pip3 install adafruit-circuitpython-uc8253
To install system-wide (this may be required in some cases):
.. code-block:: shell
sudo pip3 install adafruit-circuitpython-uc8253
To install in a virtual environment in your current project:
.. code-block:: shell
mkdir project-name && cd project-name
python3 -m venv .venv
source .env/bin/activate
pip3 install adafruit-circuitpython-uc8253
Installing to a Connected CircuitPython Device with Circup
==========================================================
Make sure that you have ``circup`` installed in your Python environment.
Install it with the following command if necessary:
.. code-block:: shell
pip3 install circup
With ``circup`` installed and your CircuitPython device connected use the
following command to install:
.. code-block:: shell
circup install adafruit_uc8253
Or the following command to update an existing version:
.. code-block:: shell
circup update
Usage Example
=============
.. code-block:: python
import time
import board
import busio
import displayio
from fourwire import FourWire
import adafruit_uc8253
displayio.release_displays()
# This pinout works on a MagTag with the newer screen and may need to be altered for other boards.
spi = busio.SPI(board.EPD_SCK, board.EPD_MOSI) # Uses SCK and MOSI
epd_cs = board.EPD_CS
epd_dc = board.EPD_DC
epd_reset = board.EPD_RESET
epd_busy = board.EPD_BUSY
display_bus = FourWire(spi, command=epd_dc, chip_select=epd_cs, reset=epd_reset, baudrate=1000000)
time.sleep(1)
display = adafruit_uc8253.UC8253(
display_bus, width=240, height=416, busy_pin=epd_busy, rotation=0, vcom_cdi=0x97
)
g = displayio.Group()
pic = displayio.OnDiskBitmap("/display-ruler-1280x720.bmp")
t = displayio.TileGrid(pic, pixel_shader=pic.pixel_shader)
g.append(t)
display.root_group = g
display.refresh()
print("refreshed")
time.sleep(display.time_to_refresh + 5)
# Always refresh a little longer. It's not a problem to refresh
# a few seconds more, but it's terrible to refresh too early
# (the display will throw an exception when if the refresh
# is too soon)
print("waited correct time")
# Keep the display the same
while True:
time.sleep(10)
