Node.js libcwiid bindings

Created by Tim Branyen @tbranyen

nodewii provides asynchronous native bindings to the libcwiid C API.

Building and installing

Dependencies

To run nodewii you need Node.js (>=v0.10.0), bluez, and libcwiid installed. To run unit tests you will need to have git installed and accessible from your PATH to fetch any vendor/ addons.

It is sufficient enough to rely on the system package manager to install libcwiid and bluez. Refer to your distros repository search to find the correct module names and installation procedure.

In action

nodewii was implemented at JSconf 2011 for Mary Rose Cook's game Pistol Slut. You can see the pull request here for how it was implemented:

maryrosecook/pistolslut#1

Video demo: http://vimeo.com/23224874

Linux (Ubuntu/Debian)

Ensure you have the dependancies installed

$ sudo apt-get install libbluetooth-dev libcwiid-dev
$ sudo npm install -g node-gyp

Install nodewii by cloning source from GitHub and use npm to build and install:

$ git clone git://github.com/bramp/nodewii.git
$ cd nodewii

$ npm -d install

A demo applicaton can be run like so:

$ node example/simple/server.js

Apple OS X/Windows via Cygwin

nodewii currently does not run on either Mac OS X or Windows machines. This is a problem with libcwiid. A future plan is to fork libcwiid and write support for at least Apple OS X.

API Example Usage

Connecting and enabling features

Raw API

var wii = require("nodewii");
var wiimote = new wii.WiiMote();

// You may specify a mac address to your wiimote, or use 00:00:00:00:00
wiimote.connect("00:00:00:00:00", function(err) {
  if( err ) {
    console.log( 'Could not establish connection' );
    return;
  }

  // Enable rumble
  wiimote.rumble(true);

  // Turn on led"s 1 and 3
  wiimote.led(1, true);
  wiimote.led(3, true);

  // Turn off led 3
  wiimote.led(3, false);

  // Get IR Data
  wiimote.ir(true);
  wiimote.on("ir", function(points) {
    for (var p in points)
      console.log("Point", p['x'], p['y'], p['size']);
  });
});
