WiringPi: An implementation of most of the Arduino Wiring functions for the Raspberry Pi
This library is deprecated. WiringPi Version 2.x is here, and there's a new Python wrapper for it: https://github.com/WiringPi/WiringPi2-Python
You can also simply: pip install wiringpi2
Existing WiringPi-Python users are encouraged to migrate. The "WiringPi2" moniker was chosen for this library to avoid unexpected updates, breakage and panics!
Prerequisites:
You must have python-dev and python-setuptools installed
sudo apt-get install python-dev python-setuptools
If you manually rebuild the bindings with swig -python wiringpi.i then cat wiringpi_class.py >> wiringpi.py to get the class-based wrapper
Get/setup repo:
git clone https://github.com/WiringPi/WiringPi-Python.git
cd WiringPi-Python
git submodule update --init
Build & install with:
sudo python setup.py install
Class-based Usage:
import wiringpi
io = wiringpi.GPIO(wiringpi.GPIO.WPI_MODE_PINS)
io.pinMode(1,io.OUTPUT)
io.digitalWrite(1,io.HIGH)
GPIO with /sys/class/gpio (You must first export the interfaces):
import wiringpi
io = wiringpi.GPIO(wiringpi.GPIO.WPI_MODE_SYS)
io.pinMode(1,io.OUTPUT)
io.digitalWrite(1,io.HIGH)
Serial:
serial = wiringpi.Serial('/dev/ttyAMA0',9600)
serial.puts("hello")
serial.close()
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(1,1) // Set pin 1 to output
wiringpi.digitalWrite(1,1) // Write 1 HIGH to pin 1
wiringpi.digitalRead(1) // Read pin 1
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
