Help Requested: Enttech Pixelator LED array

Hello,

This is my first post. I am excited to start using touchdesigner, but I am definitely a little overwhelmed. :blush:

For my fist project I am looking to control a large LED array, ideally utilizing the ENTTECH Pixelator in conjunction with the PLink injectors.
I have a video file that I am looking to break up into 6,7620 total pixels (49 rows,138 columns)

I do not know where to really start in getting touchdesigner to talk with the Pixelator.
Any help would be greatly appreciated.

Thank you,

According to the ENTTECH site it looks like youā€™ll interface with this as art-net. In TouchDesigner the DMX out CHOP can be used to talk with art-net devices.

Iā€™d start there and first sort out communication between the devices before you look at converting your video file to channel data - first nail down controlling individual pixels, then work your way up to breaking up video to send to the controller.

There are some good DMX / Art-net examples here on the forum, and if you do a bit of searching Iā€™m sure you can track some down.

Thank you Raganmd,

I am currently using DMX out CHOP, with an Art-Net interface and Packet Per Channel Format. I also have set the Network Address for the Pixelator. I have not yet gotten any pixels to ā€œdanceā€ just yet.
I will continue to actively search out solutions in the forum, but if you come across any that you think would be particularly helpful I would definitely appreciate it.

Some threads worth reading through:

Since youā€™re new to TouchDesigner and youā€™re not getting any pixel lighting going on, I would start by simplifying your system as much as possible, getting each piece working one at a time, then you can start messing around with TouchDesigner communication, and like Matthew mentioned, starting with simple channels then working up to converting images to data.

The Pixelator has a web configuration tool that you should dive into first and get it setup on your network correctly. It has some built in colour tests if I remember correctly. That way you can output some test patterns from it and make sure your connection to your Plink Injector is working fine and to make sure your pixel strips are wired correctly. Thereā€™s also a DMX generator to just output some DMX channels from the web tool. This quick start guide would be the best place to start:

If you read through that and set everything up, getting TouchDesigner talking to it should be pretty easy, as you can move onto what Matthew was saying about using some really simple test data.

There seems to be a bunch of example files on the threads he posted so you can start there or even simpler with just a Constant CHOP with channels named R, G, and B, that you connect to a DMX Out CHOP set to Art-net mode. Then you can change the channel values of the Constant CHOP between 0-255 and you should be able to get one of the pixels lighting up. Once you get that far we can help more with getting the TouchDesigner examples working, but I wouldnā€™t even touch that stuff until youā€™ve confirmed the Pixelator and Plink are setup correct and working.
