    :alt: Build Status

CircuitPython driver for Dallas 1-Wire temperature sensor.

Dependencies
=============
This driver depends on:

* `Adafruit CircuitPython <https://github.com/adafruit/circuitpython>`_
* `Adafruit OneWire <https://github.com/adafruit/Adafruit_CircuitPython_OneWire>`_

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:: python

    import board
    from adafruit_onewire.bus import OneWireBus
    from adafruit_ds18x20 import DS18X20
    ow_bus = OneWireBus(board.D2)
    ds18 = DS18X20(ow_bus, ow_bus.scan()[0])
    ds18.temperature


Contributing

Building locally
================

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 adafruit-circuitpython-ds18x20 --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.
