DisplayIO driver for SSD1305 monochrome displays

Introduction

DisplayIO driver for SSD1305 monochrome displays

For the framebuf based driver see Adafruit CircuitPython SSD1305.

Dependencies

This driver depends on:

• Adafruit CircuitPython Version 5+

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

Note

This library is not available on PyPI yet. Install documentation is included as a standard element. Stay tuned for PyPI availability!

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(max_size=10)
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(max_size=10, 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
