If you have a board with a ST7735B chip, you may want to try the Adafruit ST7735 Driver.
Dependencies
This driver depends on:
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_st7735r import ST7735R
spi = board.SPI()
tft_cs = board.D5
tft_dc = board.D6
displayio.release_displays()
display_bus = displayio.FourWire(spi, command=tft_dc, chip_select=tft_cs, reset=board.D9)
display = ST7735R(display_bus, width=128, height=128, colstart=2, rowstart=1)
# Make the display context
splash = displayio.Group(max_size=10)
display.show(splash)
color_bitmap = displayio.Bitmap(128, 128, 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)
