Línea de trabajo

Start at the HUB75 init path named in the issue, wled00/bus_manager.cpp around the linked line (~815), and compare how WLED/MM initializes FM6124/FM6126A. Add an explicit driver assignment and new HUB75 panel types (half/quarter scan) as the reporter suggested. Done when a Waveshare 64x32 FM6126A panel lights under WLED 16 on ESP32-C3; you will need that hardware or equivalent to verify.

Descripción

enhancement Feature Request
What happened?

My 64x32 HUB75 panel uses the FM6126A driver chip. It currently does not work with WLED. By studying the source code of the WLED/MM fork, I discovered that it is because the chip is not correctly initialized (my panel works with WLED/MM). Apparently, this can be already done in WLED: https://github.com/wled/WLED/blob/main/wled00/bus_manager.cpp#L815

To Reproduce Bug

Connect the Waveshare 64x32 panel.

Expected Behavior

LEDs should turn on.

Install Method

Binary from WLED.me

What version of WLED?

WLED 16.0

Which microcontroller/board are you seeing the problem on?

ESP32-C3

Relevant log/trace output

Anything else?

May I submit a PR that enables this explicit driver assignment, available as another HUB75 panel type? I can add both new options ("new half scan", "new quarter scan") if that is desirable.
