adafruit-circuitpython-ili9341 2.0.4

displayio driver for ILI9341 and ILI9340 TFT-LCD displays.

Introduction

displayio driver for ILI9341 and ILI9340 TFT-LCD displays.

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
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
