**WiringPi 2 for Python** 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:** Description incoming! **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(6,1) // Set pin 6 to 1 ( OUTPUT ) wiringpi2.digitalWrite(6,1) // Write 1 ( HIGH ) to pin 6 wiringpi2.digitalRead(6) // Read pin 6 **Setting up a peripheral:** WiringPi2 supports expanding your range of available "pins" by setting up a port expander. The implementation details of your port expander will be handled transparently, and you can write to the additional pins ( starting from PIN_OFFSET >= 64 ) as if they were normal pins on the Pi. wiringpi2.mcp23017Setup(PIN_OFFSET,I2C_ADDR) **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 **Full details at:** http://www.wiringpi.com
