Introduction

DisplayIO compatible library for SH1106 OLED displays

Dependencies

This driver depends on:

• Adafruit CircuitPython

Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle or individual libraries can be installed using circup.

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-sh1106

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

sudo pip3 install adafruit-circuitpython-displayio-sh1106

To install in a virtual environment in your current project:

mkdir project-name && cd project-name
python3 -m venv .venv
source .venv/bin/activate
pip3 install adafruit-circuitpython-displayio-sh1106

Usage Example

import busio
import displayio
import terminalio
import fourwire
from adafruit_display_text import label
import adafruit_displayio_sh1106

displayio.release_displays()

spi = busio.SPI(board.SCK, board.MOSI)
display_bus = fourwire.FourWire(
    spi,
    command=board.OLED_DC,
    chip_select=board.OLED_CS,
    reset=board.OLED_RESET,
    baudrate=1000000,
)

WIDTH = 128
HEIGHT = 64
BORDER = 5
display = adafruit_displayio_sh1106.SH1106(display_bus, width=WIDTH, height=HEIGHT)

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

color_bitmap = displayio.Bitmap(WIDTH, 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(WIDTH - BORDER * 2, 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, x=28, y=HEIGHT // 2 - 1
)
splash.append(text_area)

while True:
    pass
