Kakute H7 LEDs not working
Discussed in https://github.com/iNavFlight/inav/discussions/9682
Expected Behaviour: LEDs should turn on into colour mode when the craft is powered on. They should not blink, or indicate GPS lock, or anything else. They should just be "on"
Expected behaviour: LEDs do nothing. No blink. No wrong colour. They're just off.
Originally posted by finiteuser February 1, 2024 I installed 4x Matek 2182-8Slim LED strips. According to my multimeter I don't have any shorts, and I have good connectivity between all the grounds. And good connectivity between all the 5Vs. The D-out pads are connected to the D-in pads on the next strip, with no shorts detected between them.
I tested the voltage with the battery plugged in, and each strip is seeing 5V. I have read and re-read the wiki page at https://github.com/iNavFlight/inav/blob/master/docs/LedStrip.md and according to it, with this configuration, the LEDs should be "on," at all times. I followed along with this video: https://www.youtube.com/watch?v=kjHruLW8KT0 and according to it the LEDs should default to ON even if unconfigured. But the LEDs are not turning on. There's no flash, no blink. I tested with a multimeter (see photo) and they're definitely getting voltage. Did I turn them off? It seems weird to me that absolutely nothing is lighting up. It seems unlikely to me that I got 4 strips of completely defective LEDs. Even if one is bad, the other 31 would still light up, no?
I typed "LED" in the CLI and this is what it returned.

It seems to me that I must have inadvertently turned something off. But when I type "feature" in the CLI it returns:

This looks to me light it ought to be working. I hope I'm wrong about that, because if it isn't a user error, it's a hardware issue. Please tell me I've just configured something incorrectly. Is a 2A BEC not enough? I'm grasping at straws here.
According to the thread https://github.com/iNavFlight/inav/issues/9642 this might be a problem with the KakuteH7. Would that be a hardware problem or something that could be fixed in the next firmware release? I don't really mind waiting, but I want to know if I haven't broken something.
