WiringPi for Python
===================
WiringPi: An implementation of most of the Arduino Wiring functions for
the Raspberry Pi.
WiringPi implements new functions for managing IO expanders.
Quick Install
=============
.. image:: https://badge.fury.io/py/wiringpi.svg
:alt: PyPI version badge
:target: https://pypi.org/project/wiringpi/
The library is packaged on PyPI and can be installed with pip:
``pip install wiringpi``
Usage
=====
.. code:: python
import wiringpi
# One of the following MUST be called before using IO functions:
wiringpi.wiringPiSetup() # For sequential pin numbering
# OR
wiringpi.wiringPiSetupSys() # For /sys/class/gpio with GPIO pin numbering
# OR
wiringpi.wiringPiSetupGpio() # For GPIO pin numbering
**General IO:**
.. code:: python
wiringpi.pinMode(6, 1) # Set pin 6 to 1 ( OUTPUT )
wiringpi.digitalWrite(6, 1) # Write 1 ( HIGH ) to pin 6
wiringpi.digitalRead(6) # Read pin 6
**Setting up a peripheral:**
WiringPi supports expanding your range of available "pins" by setting up
a port expander. The implementation details of your port expander will
be handled transparently, and you can write to the additional pins
(starting from PIN\_OFFSET >= 64) as if they were normal pins on the Pi.
.. code:: python
wiringpi.mcp23017Setup(PIN_OFFSET, I2C_ADDR)
This example was tested on a quick2wire board with one digital IO
expansion board connected via I2C:
.. code:: python
wiringpi.mcp23017Setup(65, 0x20)
wiringpi.pinMode(65, 1)
wiringpi.digitalWrite(65, 1)
**Soft Tone:**
Hook a speaker up to your Pi and generate music with softTone. Also
useful for generating frequencies for other uses such as modulating A/C.
.. code:: python
wiringpi.softToneCreate(PIN)
wiringpi.softToneWrite(PIN, FREQUENCY)
**Bit shifting:**
.. code:: python
wiringpi.shiftOut(1, 2, 0, 123) # Shift out 123 (b1110110, byte 0-255) to data pin 1, clock pin 2
**Serial:**
.. code:: python
serial = wiringpi.serialOpen('/dev/ttyAMA0', 9600) # Requires device/baud and returns an ID
wiringpi.serialPuts(serial, "hello")
wiringpi.serialClose(serial) # Pass in ID
**SPI:**
The ``wiringPiSPIDataRW()`` function needs to be passed a ``bytes``
object in Python 3. In Python 2, it takes a string. The following should
work in either Python 2 or 3:
.. code:: python
wiringpi.wiringPiSPISetup(channel, speed)
buf = bytes([your data here])
retlen, retdata = wiringpi.wiringPiSPIDataRW(0, buf)
Now, ``retlen`` will contain the number of bytes received/read by the
call. ``retdata`` will contain the data itself, and in Python 3, ``buf``
will have been modified to contain it as well (that won't happen in
Python 2, because then ``buf`` is a string, and strings are immutable).
**Full details of the API at:** http://www.wiringpi.com
Manual Build
============
Get/setup repo
--------------
.. code:: bash
git clone --recursive https://github.com/WiringPi/WiringPi-Python.git
cd WiringPi-Python
Don't forget the ``--recursive``; it is required to also pull in the
WiringPi C code from its own repository.
Prerequisites
-------------
To rebuild the bindings you **must** first have installed ``swig``,
``python-dev``, and ``python-setuptools`` (or their ``python3-``
equivalents). WiringPi should also be installed system-wide for access
to the ``gpio`` tool.
.. code:: bash
sudo apt-get install python-dev python-setuptools swig wiringpi
Build & install with
--------------------
``sudo python setup.py install``
Or Python 3:
``sudo python3 setup.py install``
