I did not investigate this in great detail; but if it is displaying
characters, auxdisplay is probably right subsystem to handle that. I
guess LEDs can still take the low-level parts...
Oh, and common dimming for many LEDs is seen on other hardware, too
(Turris routers). Not sure how to handle that, either :-(.
Best regards,
