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

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

displayio.release_displays()
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
