DMX-512 controller library for node.js

npm install dmx

const DMX = require('dmx')

Create a new DMX instance. This class is used to tie multiple universes together.

• name - String
• module - Object implementing the Driver API

Register a new DMX Driver module by its name. These drivers are currently registered by default:

• null: a development driver that prints the universe to stdout
• artnet: driver for EnttecODE
• bbdmx: driver for BeagleBone-DMX
• dmx4all: driver for DMX4ALL devices like the "NanoDMX USB Interface"
• enttec-usb-dmx-pro: a driver for devices using a Enttec USB DMX Pro chip like the "DMXKing ultraDMX Micro".
• enttec-open-usb-dmx: driver for "Enttec Open DMX USB". This device is NOT recommended, there are known hardware limitations and this driver is not very stable. (If possible better obtain a device with the "pro" chip)
• dmxking-utra-dmx-pro: driver for the DMXKing Ultra DMX pro interface. This driver support multiple universe specify the options with Port = A or B

• name - String
• driver - String, referring a registered driver
• device_id - Number or Object
• options - Object, driver specific options

Add a new DMX Universe with a name, driver and an optional device_id used by the driver to identify the device. For enttec-usb-dmx-pro and enttec-open-usb-dmx device_id is the path the the serial device. For artnet it is the target ip.

• universe - String, name of the universe
• channels - Object, keys are channel numbers, values the values to set that channel to

Update one or multiple channels of a universe. Also emits a update Event with the same information.

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 devices.js 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

Create a new DMX Animation instance. This can be chained similar to jQuery.

• to - Object, keys are channel numbers, values the values to set that channel to
• duration - Number, duration in ms
• options - Object

Add an animation Step. The options Object takes an easing 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

Returns a Animation object with the animation step added.

• duration - Number, duration in ms

Delay the next animation step for duration. Returns a Animation object with the delay step added.

• universe - Object, reference to the universe driver
• onFinish - Function, called when the animation is done

Run the Animation on the specified universe.

• universe - Object, reference to the universe driver

Runs an animation constantly until animation.stop() is called

The example below shows a value being animated for 5 seconds:

const animation = new DMX.Animation().add({
  1: 255,
}, 100).add({
  1: 0,
}, 100).runLoop(universe)


setTimeout(() => {
  animation.stop()
}, 5000)

Versions prior to 0.2 included a Webinterface. This has since been moved into its own repository at https://github.com/node-dmx/dmx-web
