Fix for build missing wiringpi.py.
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.
pip install wiringpi
import wiringpi wiringpi.wiringPiSetup() # For sequential pin numbering, one of these MUST be called before using IO functions # OR wiringpi.wiringPiSetupSys() # For /sys/class/gpio with GPIO pin numbering # OR wiringpi.wiringPiSetupGpio() # For GPIO pin numbering
Setting up IO expanders (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)
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: WiringPi2 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)
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

git clone --recursive https://github.com/WiringPi/WiringPi-Python.git cd WiringPi-Python
To rebuild the bindings you must first have python-dev, python-setuptools and swig installed. Wiring Pi should also be installed system-wide for access to the gpio tool.
sudo apt-get install python-dev python-setuptools swig wiringpi
sudo python setup.py install
Or Python 3:
sudo python3 setup.py install
