Art-Net proxy – broadcast to unicast converter

 

Hi all.
Due to problems that many people have with Art-Net broadcast mode used by many programs, I have wrote a small windows application to convert Art-Net multicast / broadcast to unicast.

This involves the use of a dedicated windows XP machine with 2 ethernet adapters, to act as a “proxy”.

Don’t waste time attempting to run with only one computer proxy and controller, they DON’T WORK.

One ethernet adapter receive Art-Net broadcast from controller, and the other ethernet adapter outputs in unicast to IP adress configured for each universe.

Using Tinkerkit DMX shield with deskontrol DMX library

 

How to use TinkerKit DMX shield in UART mode with deskontrol DMX library.
With this shield you can use 1 DMX universe.

In order to use the TinkerKit DMX shield in UART mode, you need to move this bridges: DE-ENABLE, RE-ENABLE, TX-SELECT, RX-SELECT to pads 2 and 3. (the oposite as come by default)

Arduino based ArtNet-Node for led pixels

Arduino based art-net node for led pixels and digital led strips with drivers type WS2811, TM1803, TM1804, TM1809, TM1812.

In this post we show you how to build an Art-Net pixel node based on Arduino Mega with direct support for led pixels and digital led strips with drivers type WS2811, TM1803, TM1804, TM1809, TM1812. This node answers to the basic messages of the Art-Net protocol, so that any controller that meets the protocol will be able to detect it and use it.

Arduino based DMX ArtNet-Node

 

Arduino based DMX ArtNet-Node

Or how to make an Art-Net node for less than $ 50

Updated 13-01-2013

In this post we show you how to build an Art-Net node based on Arduino UNO or Arduino Mega with two output DMX universes (1024 DMX channels on mega). This node answers to the basic messages of the Art-Net protocol, so that any controller that meets the protocol will be able to detect it and use it as DMX output.

Arduino four universes DMX 512 library

After searching the web for Arduino DMX libraries, and test, we find no library allowing the use of multiple DMX universes and that did not use the timers of the arduino, so finally decided to create it.

*** UPDATED 07/07/2012 ***

Download current version: Arduino four universes dmx library version 0.3

Information about SPI digital led strips

When comparing SPI digital LED strips, we must consider the number and type of integrated (drivers) used per meter or quantity of LEDs. There are strips where only you can control three or more LEDs at a time and others where if we can handle each LED individually.
If we use the strips to display graphics on a screen, curtain or other, we would handle each pixel individually.
