I don't want to keep the CPU busy on a delay() just for blinking led,
even if only for a few micros.

Thank you =)

It's a proof of concept for now, definitely not ready for mainline.

Instead of a LED trigger + wrapper LED entry, I think this should kick in
if we set 'myled/dither=1' or something like that.

Now, do you think it would be a nice addition / Should I put more work on it?

Thanks for looking into it
