Sometimes get an emitter PCB pixel that lights up faint green

This is something I remember being discussed somewhere and “solved”.
As to the cause and fix though, I can not remember.
Does anyone remember anything about it?
Was it Blade ID scanning?

My guess is that this happens when power to those pixels is turned off?
It’s not as simple as missing SHARED_POWER_PINS, is it?

It’s not me, so I can’t say. That sounds likely if it’s a constant dull LED.
The issue I’m thinking of was an occasionally blinking dull LED.
I think it was related to BLADEID_SCAN_MILLIS. Each scan would cause a blip, so we ended up with a define to give the scan a timeout and that was the fix.
Anyway, I’ll see if I can find the guy with the issue and verify SHARED_POWER_PINS for now. Thanks.

It was indeed that - I remember finding it when I first started using BladeID. It was one of the things that led me to start experimenting with manual array switching, as it meant you wouldn’t need to leave BLADEID_SCAN_MILLIS running all the time. Though as you say, a define to shut it off is another solution.

This was the thread where I know it came up, but there might be others as well:
