Software Timers

Class member callbacks

Since 0.4.9:

A class member function can be used as a callback using this syntax to create the timer:

Timer timer(period, callback, instance, one_shot)

  • period is the period of the timer in milliseconds (unsigned int)
  • callback is the class member function which gets called when the timer expires.
  • instance the instance of the class to call the callback function on.
  • one_shot (optional, since 0.4.9) when true, the timer is fired once and then stopped automatically. The default is false - a repeating timer.
// Class member function callback example

class CallbackClass
     void onTimeout();

CallbackClass callback;
Timer t(1000, &CallbackClass::onTimeout, callback);
