    Question Re: New project - MSFS C++ USB interface

    I really shouldn't work until the wee hours in the morning. That rotary switch circuit was totally not finished.

    I've updated my pushbutton circuit.

    1. Do you see any other mistakes?

    2. Do I still need a cap at the MCU pin when it's a signal from a 74HC14?



    EDIT: Hmmm, just noticed my pull-ups on the rotary switch are between the 10K and 74HC14. Gonna go change that.

    Thanks!

    My Creality Ender 3 S1 Plus is a giant paperweight that can't even be used as a boat anchor, cause I'd be fined for polluting our waterways with electronic devices.

    Not as dumb as yesterday, but stupider than tomorrow!
