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.

Testing: Build with gcc version 4.9.3 (Ubuntu/Linaro 4.9.3-8ubuntu2~14.04) Built against Python 2.7.6, Python 3.2.3

Prerequisites: To rebuild the bindings you must first have python-dev, python-setuptools and swig installed.

You must have python-dev and python-setuptools installed If you manually rebuild the bindings with swig -python wiringpi.i

Get/setup repo:

git clone https://github.com/hardkernel/WiringPi-Python.git
cd WiringPi-Python
git submodule init
git submodule update

Build & install with: sudo python setup.py install

Or Python 3: sudo python3 setup.py install

Class-based Usage: Description incoming!

Usage:

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

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)

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/ttySAC2', 115200) # Requires device/baud and returns an ID
wiringpi.serialPuts(serial,"Hello ODROID\r\n")
wiringpi.serialClose(serial) # Pass in ID
