51 /*! \brief Stringize.
\r
53 * Stringize a preprocessing token, this token being allowed to be \#defined.
\r
55 * May be used only within macros with the token passed as an argument if the token is \#defined.
\r
57 * For example, writing STRINGZ(PIN) within a macro \#defined by PIN_NAME(PIN)
\r
58 * and invoked as PIN_NAME(PIN0) with PIN0 \#defined as A0 is equivalent to
\r
61 #define STRINGZ(x) #x
\r
63 /*! \brief Absolute stringize.
\r
65 * Stringize a preprocessing token, this token being allowed to be \#defined.
\r
67 * No restriction of use if the token is \#defined.
\r
69 * For example, writing ASTRINGZ(PIN0) anywhere with PIN0 \#defined as A0 is
\r
70 * equivalent to writing "A0".
\r
72 #define ASTRINGZ(x) STRINGZ(x)
