I have connected 15 Panels with altogether 1920 LEDs, but the virtual matrix is 2560 pixels in size (see attached pic). How can i control them with DDP from another WLED controler?

I can’t setup LED outputs with more than 2048 DDP-LEDs. Trying with 2 LED outputs (one with 2048 and one with 512 LEDs) doesn’t ssem to work.

Hi

that might a bit too much for an ESP32. I would go for xlights with a raspberry.

ESP32 can handle up to 4000 LEDs

Controlling the LEDs ist not the issue. The problem ist the use with DDP.

I did notice that DDP has the 2048 limit a while ago and I am not sure why that limit exists nor if it can be increased. you need to change code and test.
