Can a multiplexer handle more than one type of input<control surface.h>

without providing links to downloads of all the libraries your project is using
and without providing the full sketch from the very first to the very last line

any "bump" is useless

So would using cortana to speak your questions into your computer an easier way?

There is no way around posting detailed descriptions of what your code shall do and what behaviour you watch running the code.

So maybe recording a video, uploading it to youtube and posting a link is easier to show the behaviour of your code.

Your posting sounds fatalistic trying to create a huge amount of patience for you.

So my suggestion is:
Or you re-define the goal of your project:
uploading guessed code analysing what the guessed code is doing

or maybe finding a friend who is able to read your mind.

P.S.: I'm asking myself if there is an untalented kind of troll out there trying to get people investing time by slowly-low-level-trolling
