This is an unofficial port of Gordon's WiringPi library. Please do not email Gordon if you have issues, he will not be able to help.

WiringPi: An implementation of most of the Arduino Wiring functions for the Raspberry Pi.
WiringPi implements new functions for managing IO expanders.
The library is packaged on PyPI and can be installed with pip:
pip install wiringpi
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:
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.
wiringpi.mcp23017Setup(PIN_OFFSET, I2C_ADDR)
This example was tested on a quick2wire board with one digital IO expansion board connected via I2C:
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.
wiringpi.softToneCreate(PIN)
wiringpi.softToneWrite(PIN, FREQUENCY)
Bit shifting:
wiringpi.shiftOut(1, 2, 0, 123) # Shift out 123 (b1110110, byte 0-255) to data pin 1, clock pin 2
Serial:
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:
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
git clone --recursive https://github.com/khadas/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.
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.
sudo apt-get install python-dev python-setuptools swig
sudo python setup.py install
Or Python 3:
sudo python3 setup.py install
sudo apt-get update
sudo apt-get install fakeroot python3-all-dev debhelper
pip3 install stdeb
python3 setup.py --command-packages=stdeb.command sdist_dsc --debian-version 3 bdist_deb
You will find debian package in deb_dist.
