Okay, thank you for the suggestion. I looked over the code and examples but I don't have a clue where and how to attach a callback function. Sorry If this is a stupid question, but I used callbacks only once when I worked with MIDI :rolleyes:

Hello, I'm working on a realtime effects processor (delay and reverb) using the teensy audio board. I have two pots to change delay and reverb parameters using analogRead() on two pins. So far so good. Currently I use a function to read the values which is called periodically in the loop()...

For me 200*7 LEDs work bareley at 20fps. What do you think is the bottleneck here?

Is there some kind of FPS limit with Artnet? When I go over 20 FPS with 7 full universes the last pixels seem to hang. Anyone experienced that too? Is there a way go go around this?

The artnet standard only defines a maximum of 4 universes per artnet node, so especially the artnet poll reply can handle a maximum of 4 ports per device. So it won't be possible if you want more than 4 universes. Correct me if I'm wrong ;)

Thank you Titi, now all stripes at least work. What I want to achieve is that each stripe has its own universe. At the moment the code seem to assign the channels for the stripes continously over artnet borders. Is there a way to do it like I mentioned?

When I try to set const int ledsPerStrip = 160; const byte numStrips= 8; Artnet does not work. I see the test colors flashing on each of the 8 strips, but artnet does not seem to be processed. No output appears on any strip. When I set const int ledsPerStrip = 160; const byte numStrips= 1...

Hello, what is the maximum number of artnet universes per teensy? In the code I always see a kind of limit to four universes. Why?
