Can I define 16 separate devices on the same IP, on the same strip?

[l0c0luke]

I have one long LED strip of 1500 pixels going into a single GPIO on my ESP. (Using WLED)

I would like to split up the pixels into 100 pixel segments. I am not sure how the device settings and the Universe/DMX stuff work. I figure I need to create a new device of 100 pixels, and increment the universe number for each? But it seems that the second universe will always start at 512 channels from the start? Even if I define it's size 100 pixel size for the universe?

Any advice would be greatly appreciated.

There is a current discussion fielding new feature requests here: https://github.com/ahodges9/LedFx/issues/47

I'm not sure that's possible with the current configuration options. If I'm not mistaken, the current UDP configuration can support up to 256 pixels (unless someone fixed that).

In any case, the ESP is a 3.3v device. Are you sure the data signal can even reach across all 1500 LEDs?

i modified wled to handle 1920 and it works no problem on it's own. not to say some installs need special things to keep flicker out, but in general it is not the amount of LEDs that stop the signal since they propogate the signal... its long strips of cable that will do it.

as far as the udp limitation, its much more than that as I am using it on a separate installation with some 600 without issue using a single device on a single universe.

@l0c0luke can u plase share your wiring? i faced the same issue of the flicker

my setup is crazy simple with just signal and ground on gpio 4 and 5v power supply. make sure the ground is shared between the esp and the lights. be sure you have enough power. jiggle any connections. add even more power. so often it's power dippage.
