Introduction

displayio driver for ST7735R TFT-LCD displays.

Hardware

• 1.8" SPI TFT display, 160x128 18-bit color
• Adafruit 0.96" 160x80 Color TFT Display w/ MicroSD Card Breakout
• 1.8" Color TFT LCD display with MicroSD Card Breakout
• Adafruit 1.44" Color TFT LCD Display with MicroSD Card breakout
• Adafruit Mini Color TFT with Joystick FeatherWing

If you have a board with a ST7735B chip, you may want to try the Adafruit ST7735 Driver.

Dependencies

This driver depends on:

• Adafruit CircuitPython 4.0.0-beta.0+

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
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
