IP-dedicated Artnet for multiple Artnet-Nodes

Maikel Boerebach · Thu Oct 09, 2014 10:39 am

Hi everyone,
I stumbled upon a problem concerning the Artnet Plugin.
I am currently building multiple RGB-Panels controlled by an Arduino Uno.
See this link for reference: http://www.deskontrol.net/blog/arduino- ... ed-pixels/
The problem with the Arduino Uno is the lack of multiple Universes.
Therefore I am limited to 170 RGB-LEDs per Arduino.
So my idea was to use a single Arduino for each Panel (consists of 100 LEDs) with different IP-addresses.
The problem is that the Artnet-plugin embedded in QLC+ does not support the selection of a single IP-address. This causes the two Panels which i am using now to act as two mirrored animations. For my purpose i need to combine the panels to one single fixture.
So my question is: Is it possible to create a matrix with the possibility to patch certain channels to a certain IP-address?
Cheers,
Maikel

Hi Maikel,
at the moment no, it's not possible.
What you're looking for is unicast ArtNet and is not supported (yet?)

However, QLC+ ArtNet plugin broadcasts universes. So basically let's say:
- QLC+ PC : 192.168.0.100
- Arduino 1: 192.168.0.200
- Arduino 2: 192.168.0.201
- Arduino 3: 192.168.0.202

QLC+ will broadcast 3 universes on 192.168.0.255. Each Arduino will have to take only the universe they are interested into and drop the other data.
Not sure if Arduino is powerful enough for that though.
I had my experience with QLC+ to QLC+ on the Raspberry Pi and I have to say you can manage a couple of universes (1024 channels) with no lags.
Quite happy with it.
