CircuitPython SH1106 Driver

.. image:: ../docs/sh1106.jpg :width: 300px

CircuitPython driver for SH1106 OLED displays.

This driver is based on the SSD1306 driver. For a MicroPython machine API compatible library see: https://github.com/adafruit/micropython-adafruit-ssd1306

Dependencies

This driver depends on:

Adafruit CircuitPython <https://github.com/adafruit/circuitpython>_
Bus Device <https://github.com/adafruit/Adafruit_CircuitPython_BusDevice>_

Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle <https://github.com/adafruit/Adafruit_CircuitPython_Bundle>_.

Usage Example

.. code-block:: python3

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: Mark Winney heavily based on SSD1036 driver by Tony DiCola

Import all board pins.

from board import SCL, SDA import busio

Import the SH1106 module.

import sh1106

Create the I2C interface.

i2c = busio.I2C(SCL, SDA)

Create the SH1106 OLED class.

The first two parameters are the pixel width and pixel height. Change these

to the right size for your display!

display = sh1106.SH1106_I2C(128, 32, i2c)

Alternatively you can change the I2C address of the device with an addr parameter:

display = sh1106.SH1106_I2C(128, 32, i2c, addr=0x3c)

Clear the display. Always call show after changing pixels to make the display

update visible!

display.fill(0)

display.show()

Building locally

Zip release files

To build this library locally you'll need to install the circuitpython-build-tools <https://github.com/adafruit/circuitpython-build-tools>_ package.

.. code-block:: shell

python3 -m venv .env
source .env/bin/activate
pip install circuitpython-build-tools

Once installed, make sure you are in the virtual environment:

.. code-block:: shell

source .env/bin/activate

Then run the build:

.. code-block:: shell

circuitpython-build-bundles --filename_prefix circuitpython-sh1106 --library_location .

Sphinx documentation

Sphinx is used to build the documentation based on rST files and comments in the code. First, install dependencies (feel free to reuse the virtual environment from above):

.. code-block:: shell

python3 -m venv .env
source .env/bin/activate
pip install Sphinx sphinx-rtd-theme

Now, once you have the virtual environment activated:

.. code-block:: shell

cd docs
sphinx-build -E -W -b html . _build/html

This will output the documentation to docs/_build/html. Open the index.html in your browser to view them. It will also (due to -W) error out on any warning like Travis will. This is a good way to locally verify it will pass.
