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 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
