method not declared

Hi,

I'm trying to find a solution to resolve this problem but it seems that i'm getting stuck over here.

Basically i have this 3 files:

}

void loop() {
	a.light(0);
	reset_var = false;
	delay(300);
	a.menu();
	while (reset_var == false) {
		a.light(0);
	}
}

	pinMode(interruptPin, INPUT_PULLUP);

	}
	if (!read_settings()) {
		erro(2, 9);
	}
}

void change_var() {
	reset_var = true;
}

(in this one i got all the other methods declared but for the example is enough)

and i got these errors:

GamePadClass.cpp: In member function void GamePadClass::init()
 
GamePadClass.cpp: 12:55: error: 'change_var' was not declared in this scope
   attachInterrupt(digitalPinToInterrupt(interruptPin), change_var, CHANGE)
Error compiling project sources
Debug build failed for project 'GamePad'
 
GamePadClass.cpp: 13:2: error: 'rtc' was not declared in this scope
   rtc.begin()
 
GamePadClass.cpp: 14:2: error: 'mySoftwareSerial' was not declared in this scope
   mySoftwareSerial.begin(9600)

and more for every method i use from the externals classes.

Anyone know how to solve this?

PS: i already tried to have the objects of the externals classes as private on the GamepadClass and call them on the constructor using this->object = object, but keeps everything the same

Maybe this:
 
 
attachInterrupt(digitalPinToInterrupt(interruptPin), change_var, CHANGE);

should be this.
 
 
attachInterrupt(digitalPinToInterrupt(interruptPin), change_var(), CHANGE);


GamePadClass.cpp cannot see rtc. You've used it as is it's a class, but it needs to be declared.
