displayio driver for ILI9341 and ILI9340 TFT-LCD 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://github.com/adafruit/Adafruit_CircuitPython_Bundle>`_.

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

.. code-block:: python

    import board
    import displayio
    import fourwire
    import adafruit_ili9341

    # If you use explicit pins with busio.SPI(...), calling release_displays() first
    # prevents "pin in use" errors on subsequent reloads.
    displayio.release_displays()

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

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

    display = adafruit_ili9341.ILI9341(display_bus, width=320, height=240)

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

    color_bitmap = displayio.Bitmap(320, 240, 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
