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
