On ESP32 it only allows 8 LED outputs.

What happened?

Nightly Release 20250710:
I want to create 10 outputs for WS2815 LEDs (which works fine with version 0.15.0). At 9th, WS2801 automatically appears and cannot be changed. At 10th, only On/OFF or PWM can be selected.

To Reproduce Bug

Create 10 outputs

Expected Behavior

Adding 10pcs WS281X - (WS2815) outputs.

Install Method

Binary from WLED.me

What version of WLED?

Nightly Release 20250710

Which microcontroller/board are you seeing the problem on?

ESP32

Relevant log/trace output

Anything else?

No response

Why only a single pixel per output? It's possible the change you are seeing relates to a focus on stability rather than trying to drive the maximum number of parallel outputs

[sorto92]

In the final version I use 15 LEDs per output. This does not change the problem.

This the 0.15.0 version

Not a bug. Everything works as expected.
Unless you enable parallel I2S you can only have 9 digital outputs.

ohhh... there was no such setting in the stable version, so I didn't have to set it. Thank you very much!
Does this setting affect anything, or should it only be set for 10 outputs?
