DisplayIO driver for SSD1305 monochrome displays

For the framebuf based driver see Adafruit CircuitPython SSD1305.

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.

Installing from PyPI

On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally from PyPI. To install for current user:

pip3 install adafruit-circuitpython-displayio-ssd1305

To install system-wide (this may be required in some cases):

sudo pip3 install adafruit-circuitpython-displayio-ssd1305

To install in a virtual environment in your current project:

mkdir project-name && cd project-name
python3 -m venv .env
source .env/bin/activate
pip3 install adafruit-circuitpython-displayio-ssd1305

Usage Example

import board
import displayio
import terminalio
from adafruit_display_text import label
import adafruit_displayio_ssd1305

displayio.release_displays()

# Use for SPI
spi = board.SPI()
oled_cs = board.D5
oled_dc = board.D6
display_bus = displayio.FourWire(spi, command=oled_dc, chip_select=oled_cs,
                                 baudrate=1000000, reset=board.D9)

# Use for I2C
# i2c = board.I2C()
# display_bus = displayio.I2CDisplay(i2c, device_address=0x3c)

WIDTH = 128
HEIGHT = 64     # Change to 32 if needed
BORDER = 8
FONTSCALE = 1

display = adafruit_displayio_ssd1305.SSD1305(display_bus, width=WIDTH, height=HEIGHT)

# Make the display context
splash = displayio.Group()
display.show(splash)

color_bitmap = displayio.Bitmap(display.width, display.height, 1)
color_palette = displayio.Palette(1)
color_palette[0] = 0xFFFFFF # White

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(display.width - BORDER * 2, display.height - BORDER * 2, 1)
inner_palette = displayio.Palette(1)
inner_palette[0] = 0x000000 # Black
inner_sprite = displayio.TileGrid(inner_bitmap,
                                  pixel_shader=inner_palette,
                                  x=BORDER, y=BORDER)
splash.append(inner_sprite)

# Draw a label
text = "Hello World!"
text_area = label.Label(terminalio.FONT, text=text, color=0xFFFFFF)
text_width = text_area.bounding_box[2] * FONTSCALE
text_group = displayio.Group(scale=FONTSCALE, x=display.width // 2 - text_width // 2,
                             y=display.height // 2)
text_group.append(text_area) # Subgroup for text scaling
splash.append(text_group)

while True:
    pass
