When compiling in Arduino IDE 1.6.11, I receive the following error:

Metro.cpp:41:16: warning: extra tokens at end of #ifdef directive

#ifdef NOCATCH-UP

This issue appears to be resolved by changing #ifdef NOCATCH-UP to#ifdef NOCATCH_UP.

Could someone explain me what does it mean this define NOCATCH-UP and what happen in not defined? Below is part of code which I can't understnd.
#ifdef NOCATCH-UP
previous_millis = now ;
#else
previous_millis += interval_millis ;
#endif

The library and example code is very brief and clear. But I think the Metro::reset() should be called once at the begaining of every example. Maybe in setup().

IMHO, the consequence of not calling Metro::reset() is not severe as the code repeats the HIGH/LOW sequence anyway. But not initilizing previous_millis by calling Metro::reset() causes the first round of the loop being excuted immediately rather than waiting for 250ms.

Or the constructor function could initialize previous_millis by calling Metro::reset().

please try the following code:

Metro metroHeartbeat = Metro(1000);

Metro metroWithDotDefine = Metro(METROWITHDOT * 60 * 1000); // works
Metro metroWithOutDotDefine = Metro(METROWITHOUTDOT * 60 * 1000); // does not work
Metro metroWithDot = Metro(1.0 * 60 * 1000); // works
Metro metroWithOutDot = Metro(1 * 60 * 1000); // does not work
Metro metro1MinuteWithDot = Metro (60000.0); // works
Metro metro1MinuteWithOutDot = Metro (60000); // works

int counter = 1;

void setup()
{
Serial.begin(9600);
}

void loop()
{
if (metroHeartbeat.check() == 1)
{
Serial.print("Heartbeat: ");
Serial.println(counter, DEC);
counter++;
}

if (metroWithDotDefine.check() == 1)
{
Serial.println("MetroWithDotDefine_____triggered");
}

if (metroWithOutDotDefine.check() == 1)
{
Serial.println("METROWITHOUTDOTDEFINE_TRIGGERED");
}

if (metroWithDot.check() == 1)
{
Serial.println("MetroWithDot___________triggered");
}

if (metroWithOutDot.check() == 1)
{
Serial.println("METROWITHOUTDOT________TRIGGERED");
}

if (metro1MinuteWithDot.check() == 1)
{
Serial.println("Metro1MinuteWithDot____triggered");
}

if (metro1MinuteWithOutDot.check() == 1)
{
Serial.println("Metro1MinuteWithOutDot_triggered");
}
}

i never see any serial printout in capital letters ;(

can you confirm?

Tried to load the .zip library into Wiring and get the following error:
Specified folder/zip file does not contain a valid library

I'm using the latest version of Metro-Arduino-Wiring-master
