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.
WiringCB: Wiring like lib for cubieboard,change from WiringPi2-Python
sting:
Build with gcc version 4.6.3 (ubuntu/linaro 12.10) 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/gootoomoon/WiringCB-python.git
Build & install with:
cd WiringCB-python
sudo python setup.py install # python 2.7.x
sudo python3 setup.py install # python 3.2.x
Python Usage:
import wiringpi2
OUTPUT = 1
pin = 2
HIGH = 1
LOW = 0
wiringpi2.wiringPiSetupPhys() # init pin to phy mode,U14(1~48) U15(49~96)
wiringpi2.pinMode(pin,OUTPUT) # set pin 2 to output mode
while 1:
wiringpi2.digitalWrite(pin,HIGH) # Write HIGH to pin 2(U14 pin 2)
wiringpi2.delay(1000)
wiringpi2.digitalWrite(pin,LOW) # Write LOW to pin
wiringpi2.delay(1000)
General IO:
wiringpi2.pinMode(2,1) # Set pin 2 to output
wiringpi2.digitalWrite(2,1) # Write 1 HIGH to pin 2
wiringpi2.digitalRead(50) # Read pin 50(U15 pin 2)
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

Build & install with:
cd WiringPi2-Python/WiringPi/
./build.sh
C Usage:
#include <wiringPi.h>
#define OUTPUT 1
#define HIGH 1
#define LOW 0
int pin = 1;
int main()
{
wiringPiSetupPhys(); //init wiringCB lib
pinMode(pin,OUTPUT); //set pin to output mode
for(;;){
digitalWrite(pin,HIGH); //Write HIGH(1) to pin
delay(1000); //delay for 1s
digitalWrite(pin,LOW); //Write LOW(0) to pin
delay(1000); //delay for 1s
}
}
compile code like this: gcc -o test test.c -lwiringPi -lpthread
