Making getTimeStr compatible with an int function

Projects Programming
1

is there any way to make getTimeStr() compatible with getAlarm? I tried converting getAlarm to string, but nothing changed

if(rtc.getTimeStr() == getAlarm){
    tone(buzzerPin, 100);
    a=0;
    b=0;
    c=0;
  }

What are you trying to achieve?

getAlarm is a function that returns nothing (void), and you are doing a comparison from within the getAlarm function (that is, you are calling it recursively)?

is getTimeStr() a valid function? Doesn't exist in my DS3232 library, but I know there are multiple.

basically, when the clocks time is equal to the alarms time, the alarm will go off. i forgot about the void thing so thanks. yes in my library it is a function

I don't think you should be trying to call getAlarm from inside getAlarm?

In my library there is a DS3231 function to do what you want...

bool checkIfAlarm(byte Alarm); 
			// Checks whether the indicated alarm (1 or 2, 2 default);
			// has been activated.
