Introduction

displayio driver for GC9A01 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 or individual libraries can be installed using circup.

Usage Example

import board
import displayio
from gc9a01 import GC9A01

spi = board.SPI()
while not spi.try_lock():
    pass
spi.configure(baudrate=24000000) # Configure SPI for 24MHz
spi.unlock()
cs = board.D5
dc = board.D6
reset = board.D9

displayio.release_displays()
display_bus = displayio.FourWire(spi, command=dc, chip_select=cs, reset=reset)

display = GC9A01(display_bus, width=240, height=240)

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

color_bitmap = displayio.Bitmap(240, 240, 1)
color_palette = displayio.Palette(1)
color_palette[0] = 0x03C2FC

bg_sprite = displayio.TileGrid(color_bitmap, pixel_shader=color_palette, x=0, y=0)
splash.append(bg_sprite)

while True:
    pass
