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-PythonConfigure the build first:
$ cp Makefile.config.example Makefile.config
$ $EDITOR Makefile.config # Change commands to match your system setupBuild & install with:
$ make installClass-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 IDFull details at: http://www.wiringpi.com
