Simple example for binding member functions on arduino

[sticilface]

I'm quite new to this lib but i've had a good look around but can't find a solution. I'm using AVR so no std libs.

I'd like to bind member functions to a task.

I attempted to use the new '_TASK_OO_CALLBACKSbut this appears to then remove the standard constructors for tasks which i need to use as well. the scheduler is in the main sketch and running the standard example (blink every second), but I need a lib I've written to be able to bind tasks, if i globally define '_TASK_OO_CALLBACKS then everything stops working, if i include '_TASK_OO_CALLBACKSprior to#include ` in my lib then i get a lot of duplicate errors suggesting that this is not the way to do it.

I actually wrote my own taster for esp8266 https://github.com/sticilface/Tasker but it is dependent on std... so no use to me.

many thanks

You can either use static or dynamic binding - not both at the same time. Please use example 21: https://github.com/arkhipenko/TaskScheduler/tree/master/examples/Scheduler_example21_OO_Callbacks as a template for _TASK_OO_CALLBACKS

You can also send me your code to arkhipenko@hotmail.com if you want - I'll have a look.

Thank you, I am having a deep dive into you lib to understand it more as it is very extensive. I shall email you if I have any specific questions. thank you.

Look at Wokwi - a great resource to play with TS code and see an immediate impact of your changes.

This is what I ended up with...

template <typename T>
class ooTask : public Task {
public:
  ooTask(uint32_t period, uint32_t duration, T * t, void (T::*fn)() , Scheduler * aS, bool enabled) : Task(period,duration, aS, enabled), _t(t), _fn(fn) {};
  // return true if run was "productive - this will disable sleep on the idle run for next pass ?? meaning of this
  bool Callback() {
    if (_t && _fn) {
      (_t->*_fn)();
    }
  }
private:
  T * _t;
  void (T::*_fn)(); 
};

allows you to bind a class member function easily.. need to have _TASK_OO_CALLBACKS enabled

I am discovering new ways of using my own library. :)))

I've sent you an email with example about some trouble i'm having using the _TASK_OO_CALLBACKS in .h and .cpp files. I'm not sure what is happening, could you take a look?

A small example on how to use this would be really appreciated :)
