How to use your library inside my

[Samo27]

Hi,
I am trying to create my first library with arduino-timer.h. Ino sketch works fine, but when I tried to convert it to a library I get errors while compiling:

_sketch\Pirsenzor.cpp: In member function 'void Pirsenzor::restart()':
Pirsenzor.cpp:34:41: error: invalid use of non-static member function
     senzorTimer = timer.in(cas, CasKonec);
exit status 1
invalid use of non-static member function_ 

Pirsenzor.h

#ifndef Pirsenzor_h
#define Pirsenzor_h

#include "Arduino.h"
#include "arduino-timer.h"

class Pirsenzor
{
  public:
    Pirsenzor(int pinSenzor, int casSenzor);
    void srun();
    void restart();
    void reset();
    bool isHold();
    bool isSet();
    void setDelay(int x);
  private:
    Timer<3> timer;
    int pin;
    int cas = 10000;
    bool senzor = false;
    const uint8_t senzorZakasnitev = 150;
    const uint16_t senzorZanemari = 3000;
    Timer<>::Task senzorTimer; //timer za dolžino vklopa - minimalno 10000ms

  return false;
}

bool Pirsenzor::SenzorZanemari (void*) {
  senzorTimerZanemari = 0;
  return false;
}

Ino... empty for now

#include "Pirsenzor.h"

void setup() {
  // put your setup code here, to run once:

}

void loop() {
  // put your main code here, to run repeatedly:

}

I was browsing the internet for a while but everything I tried it did't work.

Thank you for any advice.

Hi,

This is failing because you're trying to pass a non-static member function from your class as a callback to timer.in().

For example,

timer.in(cas, CasKonec);

Here CasKonec is a member function of Pirsenzor and can't be passed as an argument to timer.in because it's a non-static member of Pirsenzor.

You'll need to make CasKonec a static function to be able to use it as a callback. The same goes for SenzorTimerZakasnitev, and any other non-static class member function you want to use as a callback.
