Node.js libcwiid bindings

Created by Tim Branyen @tbranyen

Currently under active development (and seeking contributors), nodewii provides asynchronous native bindings to the libcwiid C API.

Building and installing

Dependencies

To run nodewii you need Node.js, 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/Unix

Install nodewii by cloning source from GitHub and running the configure, make, and make install commands:

Note: nodewii assumes your library path exists at ~/.node_libraries you can change this by specifying a new path

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

$ ./configure
$ make
$ make install

$ make install NODE_LIB_PATH=/path/to/your/libraries

Updating to a new version

$ make update

$ make update NODE_LIB_PATH=/path/to/your/libraries

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 need to specify a mac address to your wiimote, this is unique per wiimote
wiimote.connect("00:00:00:00:00", function(err) {
  // 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(data) {
    var x = data[0];
    var y = data[1];

    console.log("Position", x, y);
  });
});
