This is a small node.js GPIO library for the Raspberry Pi using the fastest way to export values via C (http://codeandlife.com/2012/07/03/benchmarking-raspberry-pi-gpio-speed/).

Installation:

npm install fastgpio

In your node.js file just require the library:

var fastgpio = require( "fastgpio" );

Now you can prepare your GPIO for output using:

fastgpio.prepareGPIO(18);

After that you can set your GPIO to HIGH (turn on) anytime with:

fastgpio.set(18);

Or you can set your GPIO to LOW (turn off) anytime with:

fastgpio.unset(18);

The library only supports GPIOs as output, but in the fastest possible way from node.js. It uses the standard Raspberry Pi GPIO numbers.
