I have this set of example code that all rely on a common include file that contains hardware definitions.
For now, I solved it like this:
neomatrix_config.h is a symlink to ../neomatrix_config.h
that way, I can change that include/config file, and all the demos get the new one.
This library has the same need:
Adafruit demos that refer to a display with specific configs and pins, have the same need too.
What is the best way to use a common config file for all such demos without using symlinks, as symlinks work great, except on windows where they do not work at all.
I could have some config.h file that then includes "../config.h" but I'm not sure the arduino IDE will be super happy with that, or if there is some other/better way.
