displayio Driver for HX8357 Displays such as the 3.5-inch TFT FeatherWing and Breakout


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://github.com/adafruit/Adafruit_CircuitPython_Bundle>`_.

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

.. code-block:: python

    import board
    import displayio
    from fourwire import FourWire
    from adafruit_hx8357 import HX8357

    spi = board.SPI()
    tft_cs = board.D9
    tft_dc = board.D10

    displayio.release_displays()
    display_bus = FourWire(spi, command=tft_dc, chip_select=tft_cs)

    display = HX8357(display_bus, width=480, height=320)

    # Make the display context
    splash = displayio.Group()
    display.show(splash)

    color_bitmap = displayio.Bitmap(480, 320, 1)
    color_palette = displayio.Palette(1)
    color_palette[0] = 0xFF0000

    bg_sprite = displayio.TileGrid(color_bitmap,
                                   pixel_shader=color_palette,
                                   x=0, y=0)
    splash.append(bg_sprite)

    while True:
        pass
