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./* in a header file */ const uint8_t STATUS_LED = 3; static inline void turnLedOn(void) { PORTA |= _BV(STATUS_LED); } /* in your main C source */ #include "myIODefinitions.h" ... turnLedOn(); ...
You're absolutely correct, that's the next step in the progression in putting a layer of abstraction away from the underlying hardware.
