* | |
* 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". | |
