DMXOut WLED issues

Hello,

I’m struggling to address two WLED strips on one esp2866 plug and play 12v controller. They’re both 300 pixels long on seperate GPI0s and the best I’ve done is to address the first 512 pixels of the pair by creating two universes the first with 0-300 samples of RGB data and the second with the rest trimmed to 300-512, merged and inputted. I can’t then export anymore from the same DMXOut as the samples in go above 512. I know if most cases you would start a new universe at 0-300 I’m guessing as I’ve set up 0-300 on one GPI01 and 300-600 on GPI02 WLED is looking for data up to 600 and can’t calculate two sets of 300. I’ve tried doing two DMXOuts one with 0-300 the other 300-600 data but I’m getting nothing there. I’ve also tried shuffling to 512, but it has the same effect, presumably because it’s resetting to 0 for the second set of data and essentially sending to the lower end again and not reaching LEDS up to 600.

I was on aSCN but as data is reserve on universe0 my first strip wasn’t getting data so swapped to ARTNET and this is the best I could get, 512 pixels.

Is this a WLED issue, do you think I wouldn’t have this issue if I swapped to the equivalent ESP32 controller instead?

Weird one!

Hi @Maitriix,

can you share your project here?

Hi @Maitriix,

an RGB LED will occupy 3 DMX channels, 1 per color. So to address a strip of 300 LEDs you will need to span across 2 universes as this will be occupying 900 dmx channels each. Does your controller support that?

A possible solution for your lookups would be to first lookup the values for each strip and then shuffle and split into 512 sample channels which you now can use as DMX universes. For sACN your first universe should just be universe 1 which you can set in the routing table.

Attached is a sample showing the described.

Thanks Markus! All sorted.
