WiringPi 2 for Python

WiringPi: An implementation of most of the Arduino Wiring functions for the Raspberry Pi

WiringPi2: WiringPi version 2 implements new functions for managing IO expanders.

Testing: Build with gcc version 4.6.3 (Debian 4.6.3-14+rpi1) Built against Python 2.7.2, Python 3.2.3

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

YOU MUST FIRST INSTALL WIRINGPI2!!

git clone git://git.drogon.net/wiringPi cd wiringPi sudo ./build

Get/setup repo: git clone https://github.com/Gadgetoid/WiringPi2-Python.git cd WiringPi2-Python

Build & install with: sudo python setup.py install

Or Python 3 sudo python3 setup.py install

Class-based Usage: Description incoming!

Usage:

import wiringpi2
wiringpi2.wiringPiSetup // For sequential pin numbering, one of these MUST be called before using IO functions
OR
wiringpi2.wiringPiSetupSys // For /sys/class/gpio with GPIO pin numbering
OR
wiringpi2.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):

wiringpi2.mcp23017Setup(65,0x20)
wiringpi2.pinMode(65,1)
wiringpi2.digitalWrite(65,1)

General IO:

wiringpi2.pinMode(1,1) // Set pin 1 to output
wiringpi2.digitalWrite(1,1) // Write 1 HIGH to pin 1
wiringpi2.digitalRead(1) // Read pin 1

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.

wiringpi2.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.

wiringpi2.softToneCreate(PIN)
wiringpi2.softToneWrite(PIN,FREQUENCY)

Bit shifting:

wiringpi2.shiftOut(1,2,0,123) // Shift out 123 (b1110110, byte 0-255) to data pin 1, clock pin 2

Serial:

serial = wiringpi2.serialOpen('/dev/ttyAMA0',9600) // Requires device/baud and returns an ID
wiringpi2.serialPuts(serial,"hello")
wiringpi2.serialClose(serial) // Pass in ID
