DEBUG()

[copych]

On the web I have found one smart tip, so suggest modifying sparkStructures.h with this:

#define DEBUG_ON          // Comment this line out for a production build

#ifdef DEBUG_ON
#define DEBUG(...) Serial.println(__VA_ARGS__) 
#else
#define DEBUG(...)
#endif

it can accept any number of args, like DEBUG(0x0170, HEX) , so there will be no more need to use print(). And globally (un-)defined DEBUG_ON could switch the entire project to clean production build.

Nice - but will Serial.println accept multiple arguments? Like DEBUG(“Hi”, 12, “people”)

It only duplicates what println can do. But it accepts concatenation: DEBUG("Hi " + String(12) + " people");

Sometimes .print is needed, so I modified my local copy as following:

#define DEBUG_ON          // Comment this line out for a production build

#ifdef DEBUG_ON
#define DEB(...) Serial.print(__VA_ARGS__) 
#define DEBUG(...) Serial.println(__VA_ARGS__) 
#else
#define DEB(...)
#define DEBUG(...)
#endif

this'd keep compatibility with the existing code
