skyportal

This is a top-level interface to an rfid reader and writer that happens to double as a very nice glowy thing. The library itself have been written to support multiple skyportals on the one machine allowing you do so some pretty neat things when you have a few usb ports spare :)

NPM

experimental

Usage

This module does just the bare bones required to communicate with the device, but does make interfacing with a skyportal pretty accessible. The follow example demonstrates opening a portal and setting it's color to green.

var skyportal = require('skyportal');
var commands = skyportal.commands;

skyportal.open(skyportal.find(), function(err, portal) {
  skyportal.send(commands.color(0, 0, 0), portal);
});

NOTE: Running the examples (at least on my machine required root user privileges to open the device, so you may need to sudo the examples).

Compatibility

At this stage this has only been tested with the USB version of the portal (Xbox 360) on Linux. It has been coded in such a way that compatibility with other portal models is quite easy to implement, so feel to send through a pull request :)

Reference

skyportal.open(portal, callback)

Open the portal using the portal data that has been retrieved from a find operation.

skyportal.read(portal, callback)
