Hey friends.
Its me again and i stuck again. I am using a Nextion and an ESP32
I try to learn how to stop a running function. To be more specific. I have a Start and a Stop button.
When i push the START button: A counter in a textfield starts to count down and a LED turns off.
When i push the STOP button: I want to stop the counter and turn the LED off. (In the futre the LED will be replaced with a motor, and i want a STOP button to stop everything)
My problem right now is, i cant figure it out how to manage it, that my code recognizes that the STOP button was pushed and cancles my counter routine.
Here the code:
class EineKlasse
{
private:
double value;
int value2;
public:
void set_value(double v);
double get_value();
void set_value2(int v);
int get_value2();
};
void EineKlasse::set_value(double v)
{
value = v;
}
void EineKlasse::set_value2(int v)
{
value2 = v;
}
double EineKlasse::get_value()
{
return value;
}
int EineKlasse::get_value2()
{
return value2;
}
class Kalibrieren
{
private:
int menge;
int zeit;
double durchschnitt;
public:
Kalibrieren(int z, int m)
{
zeit = z,
menge = m;
}
int get_time()
{
return zeit;
}
int get_menge()
{
return menge;
}
double CalcDurchschnitt()
{
return (((double(menge)/double(zeit))*3600)/1000);
}
};

I am kinda frustrated. I know that this code is false. But i am unable to figure it out how to solve the puzzle. I know that somehow the info, that the STOP button was pushed must interrupt the while loop.
Anyone has an idea?
Thank you for all the support
best regards
