adafruit-circuitpython-ssd1331 1.4.1

介绍

SSD1331显示屏的displayio驱动程序

依赖项

此驱动程序依赖于

• Adafruit CircuitPython

请确保所有依赖项都可在CircuitPython文件系统中使用。这可以通过下载Adafruit库和驱动程序捆绑包轻松实现。

使用示例

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
