+# node-dmx
+
+DMX-512 controller library for node.js - also includes a Webinterface and HTTP API.
+
+## Webinterface
+
+### Configuration
+
+The Daemon <code>dmx-web</code> looks for a configuration file in <code>/etc/dmx-web.json</code>. An alternate location can be passed as a command line argument.
+
+This configuration file consists of three sections:
+
+- Server
+- Universes
+- Presets
+
+In the Server section you can set the listen port and host.
+Under Universes you describe the DMX Universes with details like which output driver to use and which devices are at which address.
+The presets section allows you to specify a state some channels should be set when the preset is called.
+
+A example configuration is in the repository by the name <code>dmx-web-example.conf</code>
+
+### Run
+
+	dmx-web [-c <config file>]
+
+### Animation HTTP API
+
+A List of Channel Transistions can be POSTed to <code>/animation/&lt;universe&gt;</code>. Each transistion is a JSON Object with at least the <code>to</code> property present. The Value of which also has to be an Object describing the channel end-states.
+
+A duration for this transistion can be given in the <code>duration</code> property.
+If not specified 0ms is assumed.
+
+Example:
+
+	[
+		{"to": {"10": 0, "20": 0}},
+		{"to": {"10": 255}, "duration": 2000},
+		{"to": {"20": 255}, "duration": 1000}
+	]
+
+This sets channels 10 and 20 to zero. Then transistions channel 10 to 255 in 2 seconds. After that channel 20 is faded to 255 in 1 second.
+
+## Library API
+
+	var DMX = require('dmx')
+
+### Class DMX
+
+#### new DMX()
+
+Create a new DMX instance. This class is used to tie multiple universes together.
+
+#### dmx.registerDriver(name, module)
+
+- <code>name</code> - String
+- <code>module</code> - Object implementing the Driver API
+
+
+Register a new DMX Driver module by its name.
+Two Drivers are currently registered by default:
+
+- null: a development driver that prints the universe to stdout
+- enttec-usb-dmx-pro: a driver for devices using a Enttec USB DMX Pro chip like the "DMXKing ultraDMX Micro". This driver requires the ftdi module (<https://github.com/KABA-CCEAC/node-ftdi>)
+
+#### dmx.addUniverse(name, driver, device_id)
+
+- <code>name</code> - String
+- <code>driver</code> - String, referring a registered driver
+- <code>device_id</code> - Number or Object
+
+Add a new DMX Universe with a name, driver and an optional device_id used by the driver to identify the device.
+
+#### dmx.update(universe, channels)
+
+- <code>universe</code> - String, name of the universe
+- <code>channels</code> - Object, keys are channel numbers, values the values to set that channel to
+
+Update one or multiple channels of a universe. Also emits a <code>update</code> Event with the same information.
+
+
+#### DMX.devices
+
+A JSON Object describing some Devices and how many channels they use.
+Currently not many devices are in there but more can be added to the <code>devices.js</code> file. Pull requests welcome ;-)
+
+The following Devices are known:
+
+- generic - a one channel dimmer
+- showtec-multidim2 - 4 channel dimmer with 4A per channel
+- eurolite-led-bar - Led bar with 3 RGB color segments and some programms
+- stairville-led-par-56 - RGB LED Par Can with some programms
+
+### Class DMX.Animation
+
+#### new DMX.Animation()
+
+Create a new DMX Animation instance. This can be chained similar to jQuery.
+
+#### animation.add(to, duration, options)
+
+- <code>to</code> - Object, keys are channel numbers, values the values to set that channel to
+- <code>duration</code> - Number, duration in ms
+- <code>options</code> - Object
+
+Add an animation Step.
+The options Object takes an <code>easing</code> key which allows to set a easing function from the following list:
+
+- linear (default)
+- inQuad
+- outQuad
+- inOutQuad
+- inCubic
+- outCubic
+- inOutCubic
+- inQuart
+- outQuart
+- inOutQuart
+- inQuint
+- outQuint
+- inOutQuint
+- inSine
+- outSine
+- inOutSine
+- inExpo
+- outExpo
+- inOutExpo
+- inCirc
+- outCirc
+- inOutCirc
+- inElastic
+- outElastic
+- inOutElastic
+- inBack
+- outBack
+- inOutBack
+- inBounce
+- outBounce
+- inOutBounce
+
+#### animation.delay(duration)
+
+- <code>duration</code> - Number, duration in ms
+
+Delay the next animation step for duration.
+
+#### animation.run(universe, onFinish)
+
+- <code>universe</code> - Object, reference to the universe driver
+- <code>onFinish</code> - Function, called when the animation is done
