Even better, use higher-level constructs like inline functions (better than macros, because they're type-safe and can do more). In this case, of course, it would be easy to do with a macro.

static inline
void turnLedOn(void)

/* in your main C source */

#include "myIODefinitions.h"


You're absolutely correct, that's the next step in the progression in putting a layer of abstraction away from the underlying hardware.
