displayio driver for SSD1331 TFT-LCD displays.
Project description
Introduction
displayio drivers for SSD1331 Displays
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
# Starting in CircuitPython 9.x fourwire will be a seperate internal library
# rather than a component of the displayio library
try:
from fourwire import FourWire
except ImportError:
from displayio import FourWire
import terminalio
from adafruit_display_text import label
from adafruit_ssd1331 import SSD1331
spi = board.SPI()
tft_cs = board.D5
tft_dc = board.D6
displayio.release_displays()
display_bus = FourWire(spi, command=tft_dc, chip_select=tft_cs, reset=board.D9)
display = SSD1331(display_bus, width=96, height=64)
# Make the display context
splash = displayio.Group()
display.root_group = splash
color_bitmap = displayio.Bitmap(96, 64, 1)
color_palette = displayio.Palette(1)
color_palette[0] = 0x00FF00 # Bright Green
bg_sprite = displayio.TileGrid(color_bitmap,
pixel_shader=color_palette,
x=0, y=0)
splash.append(bg_sprite)
# Draw a smaller inner rectangle
inner_bitmap = displayio.Bitmap(86, 54, 1)
inner_palette = displayio.Palette(1)
inner_palette[0] = 0xAA0088 # Purple
inner_sprite = displayio.TileGrid(inner_bitmap,
pixel_shader=inner_palette,
x=5, y=5)
splash.append(inner_sprite)
# Draw a label
text = "Hello World!"
text_area = label.Label(terminalio.FONT, text=text, color=0xFFFF00, x=12, y=32)
splash.append(text_area)
while True:
pass
