node-wiring-pi is based on https://github.com/WiringPi/WiringPi-Node
It differs from the original project by:
Using a vanilla WiringPi.com install, rather than a customised build.
This version of the node bindings will be missing features that have been added to https://github.com/WiringPi/WiringPi-Node.
Using NAN to provide Node version abstraction Hopefully this makes it more resilient against Node API changes
This should mean that installation is simpler, and supports npm install -g (global mode).
Make sure you have WiringPi installed. On Raspbian Jessie, this should be as easy as:
sudo apt-get install wiringpiSee the WiringPi link for more options and details.
To install this node module:
npm install node-wiring-pivar wpi = require('node-wiring-pi');
