adafruit-circuitpython-ssd1306 2.12.21

CircuitPython library for SSD1306 OLED displays.

Introduction

Adafruit CircuitPython driver for SSD1306 or SSD1305 OLED displays. Note that SSD1305 displays are back compatible so they can be used in-place of SSD1306 with the same code and commands.

This driver implements the adafruit_framebuf interface. It is not the displayio driver for the SSD1306. See the Adafruit CircuitPython DisplayIO SSD1306 driver for displayio support.

Dependencies

This driver depends on:

• Adafruit CircuitPython

• Bus Device

• Adafruit framebuf

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-ssd1306

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

sudo pip3 install adafruit-circuitpython-ssd1306

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-ssd1306

Usage Example

# Basic example of clearing and drawing pixels on a SSD1306 OLED display.
# This example and library is meant to work with Adafruit CircuitPython API.
# Author: Tony DiCola
# License: Public Domain

# Import all board pins.
from board import SCL, SDA
import busio

# Import the SSD1306 module.
import adafruit_ssd1306


# Create the I2C interface.
i2c = busio.I2C(SCL, SDA)

# Create the SSD1306 OLED class.
# The first two parameters are the pixel width and pixel height.  Change these
# to the right size for your display!
display = adafruit_ssd1306.SSD1306_I2C(128, 32, i2c)
# Alternatively you can change the I2C address of the device with an addr parameter:
#display = adafruit_ssd1306.SSD1306_I2C(128, 32, i2c, addr=0x31)

# Clear the display.  Always call show after changing pixels to make the display
# update visible!
display.fill(0)

display.show()

# Set a pixel in the origin 0,0 position.
display.pixel(0, 0, 1)
# Set a pixel in the middle 64, 16 position.
display.pixel(64, 16, 1)
# Set a pixel in the opposite 127, 31 position.
display.pixel(127, 31, 1)
display.show()

More examples and details can be found in the adafruit_framebuf docs.
