WARNING: This is an in-development library, it will not be bug free and fully featured.

Please tweet @gadgetoid, find Gadgetoid in IRC, email Phil at Gadgetoid dot com, or visit http://pi.gadgetoid.com/post/039-wiringpi-version-2-with-extra-python and comment if you have any problems, suggestions, questions or words of support.

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

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:

No classes have been created for this version yet.

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

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
