🐛 Multi RGB DMX Mode breaks when using multiple universes

[lukas-runge]

What happened?

When using more than 170 Single Pixel LEDs (WS2815) with WLED in Multi RGB DMX Mode, the ArtNet DMX Input is wrongly passed on to the LEDs. The first LED in Universum 2 is 172 instead of 171 and LED 171 is flickering at all times.

To Reproduce Bug

This bug can be reproduced 100% of the time when controlling WLED via ArtNet with more than 170 LEDs.

Expected Behavior

LED 171 should be the first LED of Universe 2. It should not flicker.

Install Method

Binary from WLED.me

What version of WLED?

WLED version 0.13.3

Which microcontroller/board are you seeing the problem on?

ESP32

Relevant log/trace output

none

Anything else?

I uploaded a video to youtube that shows the behaviour: https://youtu.be/rsJUAhyQ6lI 🙌

I came here to say the same thing. In my experience with other controllers - you're able to set universe size on the controller, which allows you to use it with different software implementations.

universe size 510 is great if you're using certain software - but with mine, Resolume Arena, it auto-spans the universe + addressing automatically - so with my WLED controller - it will work like mentioned above, for the first 170 pixels, or 510 channels, leaving that same pixel, channels 511 and 512 without getting data. and every pixel beyond that is off by one address.

Hey! This issue has been open for quite some time without any new comments now. It will be closed automatically in a week if no further activity occurs. Thank you for using WLED! ✨
