#define ASTRINGZ (   x)    STRINGZ(x)

Absolute stringize.

Stringize a preprocessing token, this token being allowed to be #defined.

No restriction of use if the token is #defined.

For example, writing ASTRINGZ(PIN0) anywhere with PIN0 #defined as A0 is equivalent to writing "A0".

#define STRINGZ (   x)    #x

Stringize.

Stringize a preprocessing token, this token being allowed to be #defined.

May be used only within macros with the token passed as an argument if the token is #defined.

For example, writing STRINGZ(PIN) within a macro #defined by PIN_NAME(PIN) and invoked as PIN_NAME(PIN0) with PIN0 #defined as A0 is equivalent to writing "A0".
