a nodejs gpio library for the raspberry pi using the fastest way to export values
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/).
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:
After that you can set your GPIO to HIGH (turn on) anytime with:
Or you can set your GPIO to LOW (turn off) anytime with:
The library only supports GPIOs as output, but in the fastest possible way from node.js. It uses the standard Raspberry Pi GPIO numbers.
