# WiringPi for Python

WiringPi: An implementation of most of the Arduino Wiring
functions for the Raspberry Pi

WiringPi implements new functions for managing IO expanders.

# Quick Install

pip install wiringpi

# 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

Setting up IO expanders (This example was tested on a quick2wire board with one digital IO expansion board connected via I2C):

wiringpi.mcp23017Setup(65,0x20) wiringpi.pinMode(65,1) wiringpi.digitalWrite(65,1)

General IO:

wiringpi.pinMode(6,1) # Set pin 6 to 1 ( OUTPUT ) wiringpi.digitalWrite(6,1) # Write 1 ( HIGH ) to pin 6 wiringpi.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.

wiringpi.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.

wiringpi.softToneCreate(PIN) wiringpi.softToneWrite(PIN,FREQUENCY)

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

# Manual Build

## Get/setup repo `bash git clone --recursive https://github.com/WiringPi/WiringPi-Python.git cd WiringPi-Python `

## Prerequisites To rebuild the bindings you must first have python-dev, python-setuptools and swig installed. Wiring Pi should also be installed system-wide for access to the gpio tool. `bash sudo apt-get install python-dev python-setuptools swig wiringpi `

## Build & install with

sudo python setup.py install

Or Python 3:

sudo python3 setup.py install
