grizzled wind
Hi all, I seem to have a strange issue with my HYD FUEL PCB. It is a RaspberryPico board with built in LEDs. When the brightness is lowered to 0 I am seeing the board LEDs flicker, see attached video.
Worth noting I am using the Fenix A320, see attached output config also. If anyone needs any more info/screenshots let me know. Slightly odd as all my other boards are set up this exact way and I don't see the issue with them. TIA

Please also show the input and output configs

Apologies, please see inputs (on left, on right) and also output for backlight brt. I did notice an update to the preset for the output which had *100 at the end. However I have tried this with and without and still seeing the same issue

Does the brightness variable value stay stable at 0 when your panel flickers?
Does the PWM signal go to a FET to control backlight?

Yeah stays at 0, as for PWN signal, I am using RaspberryPico boards with on board LEDs (no FET) board is powered by 12v in/out
What makes this even stranger is if I sort the description by name order in MF, the LEDs then come fully on. Will have to record this on my phone so you are able to see the board
I know you can’t see but I am clicking sort by description on here

OK, where does backlight brt pin 15 go to?
You said no FET for backlights, so how do you control the panel flickering backlights?
It sounds like an issue in the wiring to the EN pin.

Sorry you’re right it is a FET for backlighting!
pwn output (led) to mosfet

agree it is very strange that sorting by description generates an error
