TaskScheduler in custom library

[R1Snake]

Hi,

i want to declare and define a TaskScheduler in my custom library but I have a problem with the declaration.

This ist my Code:

TaskExample.h:

`#ifndef TaskExample_h

define TaskExample_h

include

class TaskExample { public: TaskExample(); void defineMyTask(); void taskToExecute();

Task *myTask;
Scheduler ts;

};

endif`

TaskExample.cpp:

`#include "TaskExample.h"

TaskExample::TaskExample(){}

void TaskExample::defineMyTask(){ myTask = new Task (500,TASK_FOREVER, TaskExample::taskToExecute, &ts, false); // Funktioniert nicht (Falsche Parameter) myTask = new Task (500,TASK_FOREVER, externalVoid, &ts, false); // Funktioniert, bringt mir jedoch nichts }

void externalVoid(){ Serial.println("Ich werde ausgeführt, habe aber keinen Klassenbezug"); }

void TaskExample::taskToExecute(){ Serial.println("Ich werde ausgeführt"); }

`

In "defineMyTask" i got an error because i have the wrong parameters and the second line works fine. What I have to do to enter my library void into the declaration?

I am not sure what you are trying to achieve, therefore it is hard to help.

Generally, TaskScheduler is used with static Task definitions in a non-class implementation. There is a way to implement Tasks in a true OO style: there is no documentation, but you have to study and follow example #21: https://github.com/arkhipenko/TaskScheduler/tree/master/examples/Scheduler_example21_OO_Callbacks

If you want to include TaskScheduler in your library, the best example is pailessMesh: https://gitlab.com/painlessMesh/painlessMesh it uses advice from https://github.com/arkhipenko/TaskScheduler/wiki/Creating-TaskScheduler---friendly-libraries

Hope this helps. Regards Anatoli

My target is only to execute a library void with the task scheduler.

It is important that the TaskScheduler is defined and declared in the library because I want the library "standalone" and the task has to work with the library objects.

I am sorry, I do not understand what "execute a library void" means.

Work with xTaskCreate because i get an error that Task is already defined if I include your library in my custom library and in main.cpp.
