I seem to be able to define a class in the .h file, but run into various errors when implementing the class in the corresponding .cpp file.  The same syntax works if I put the implementation inline in the .h and use the .cpp file only for its "#include switches.h" functionality.

The other issue is one of scope.  I need setup() to initialize files, preferably instantiate them as well, but I need them accessible in loop(). The only way I've found to do this is to make them global, but the "static" operator seems to cause errors also.

Is there some kind of Arduino uniqueness going on here, or am I just missing some basic OO issue or syntax?
