displayio driver for ST7735R TFT-LCD displays.

Hardware

• 1.8" SPI TFT display, 160x128 18-bit color <https://www.adafruit.com/product/618>_
• Adafruit 0.96" 160x80 Color TFT Display w/ MicroSD Card Breakout <https://www.adafruit.com/product/3533>_
• 1.8" Color TFT LCD display with MicroSD Card Breakout <https://www.adafruit.com/product/358>_
• Adafruit 1.44" Color TFT LCD Display with MicroSD Card breakout <https://www.adafruit.com/product/2088>_
• Adafruit Mini Color TFT with Joystick FeatherWing <https://www.adafruit.com/product/3321>_

If you have a board with a ST7735B chip, you may want to try the Adafruit ST7735 Driver <https://github.com/adafruit/Adafruit_CircuitPython_ST7735>_.

Dependencies

This driver depends on:

• Adafruit CircuitPython 4.0.0-beta.0+ <https://github.com/adafruit/circuitpython>_

Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle <https://github.com/adafruit/Adafruit_CircuitPython_Bundle>_.

Usage Example

.. code-block:: python

import board
import displayio
import fourwire
from adafruit_st7735r import ST7735R

spi = board.SPI()
tft_cs = board.D5
tft_dc = board.D6

displayio.release_displays()
display_bus = fourwire.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()

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)

while True:
    pass
