CircuitPython `displayio` driver for SSD1677-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>`_.

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-ssd1677/>`_.
To install for current user:

.. code-block:: shell

    pip3 install adafruit-circuitpython-ssd1677

To install system-wide (this may be required in some cases):

.. code-block:: shell

    sudo pip3 install adafruit-circuitpython-ssd1677

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-ssd1677

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_ssd1677

Or the following command to update an existing version:

.. code-block:: shell

    circup update

Usage Example
=============

.. code-block:: python

    import time
    import board
    import displayio
    import fourwire
    import adafruit_ssd1677

    displayio.release_displays()

    spi = board.SPI()
    epd_cs = board.EPD_CS
    epd_dc = board.EPD_DC
    epd_reset = board.EPD_RESET
    epd_busy = board.EPD_BUSY

    display_bus = fourwire.FourWire(
        spi, command=epd_dc, chip_select=epd_cs, reset=epd_reset, baudrate=1000000
    )
    time.sleep(1)
    display = adafruit_ssd1677.SSD1677(
        display_bus,
        width=800,
        height=480,
        busy_pin=epd_busy,
        rotation=0,
    )

    g = displayio.Group()

    pic = displayio.OnDiskBitmap("/display-ruler-720p.bmp")
    t = displayio.TileGrid(pic, pixel_shader=pic.pixel_shader)

    g.append(t)
    display.root_group = g
    display.refresh()
