Sounds more like a #define than an error :wink:

o... thanks it a define a constant of VERBOSE on pin 1 :slight_smile: :slight_smile: lots of thanks...

may i know that the below several rung is using if statement??

#ifdef VERBOSE //debugging output wont slow down our time sensitive interrupt
pinMode(DEBUG_PIN, OUTPUT);
digitalWrite(DEBUG_PIN, LOW);
Serial.println("----- VERBOSE -----"); // feeling talkative?
#endif

o... thanks it a define a constant of VERBOSE on pin 1

Not likely. It is more likely that it defines a name, VERBOSE, with a value, 1.

Post the damned code.

may i know that the below several rung is using if statement??

It is using a pre-processor directive based on an if condition.

thanks
