WiringPi: An implementation of most of the Arduino Wiring functions for the Raspberry Pi
Prerequisites: You must have python-dev installed 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
