I'd like to know if it's possible to create a library for Arduino that does not contain a class, just functions.
I know how to create a library with a class, but I'd like to create a library of general purpose functions that don't need to be instantiated to be used. Just used like the standard functions included in the Arduino IDE: sizeof(), etc..
Is this possible? If so, can anyone point me in the direction of a template? I've been searching, but haven't found anything.
