I have connected a Model F USB (New Models) controller bought from Model F Labs with firmware version 0.9.1 on it and I have an issue with lock lights pannel connected to it. The issue is that when lock is active the actual indication is switched off, and when lock is off the light is on.
Hello, please do head over to the Deskthority forum for all technical questions. I can confirm with my LED testing on xwhatsit controllers (great way to add LED lock lights to an F77 or F62) over the years that I have not seen the behavior you describe. Please note that the pinout is reversed from what is in the xwhatsit manual as per the product page description:

I swapped actions inside three branchings of setLockLEDs() function inside exp.c, recompiled and everything started to work as it should. I am in grate doubt it capable to work correctly without these changes. I am not good in electronics, but I believe I made no mistakes in wiring either. The case is somewhat mysterious.
