Introduction¶

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

Dependencies¶

This driver depends on:

Adafruit CircuitPython

Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle.

Usage Example¶

import board
import displayio
from adafruit_hx8357 import HX8357

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

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

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

# Make the display context
splash = displayio.Group(max_size=10)
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
