TimerManager

Run as many timers as you want

On Teensy, at most three IntervalTimers can be active at one time. TimerManager, which benefits from IntervalTimer, enables you to run as many timers as you want simultaneously. Moreover, you can also set any class's member function as a callback function, as long as the class inherits from the TimerListener class.

Example

First implements the TimerListener in DoSomething.h and override onTimerCall():

#include "TimerListener.h"

class DoSomething : public TimerListener {
public:
    void onTimerCall(); // Remember to write the function body.
};

Then in main.ino:

// 1.
#include "TimerManager.h"
#include "List.h"
#include "DoSomething.h"

void setup() {
    // 2.
    TimerManager *timerManager = TimerManager::getInstance();
    // 3.
    timerManager->setResolution(0, 100000);
    // 4.
    timerManager->addTimerAndStart(0, 1, 10, new DoSomething());
}

void loop() {
}

1. Include the first two headers for TimerManager. Then include the third, which is the class you want to call when timer calls.
2. Get the instance of TimerManager.
3. Set the first resolution to 0.1 second. The period of a timer will be a interger multiple of the resolution.
4. Add a timer using the first resolution, with period of 1 second, running 10 periods, and listened by DoSomething. The timer starts immediately.

In this example, a timer will call DoSomething::onTimerCall() every one second and call ten times totally.

For detailed information please refer to the user manual (available soon).

Project status

Basic functions are completed, though not thoroughly tested. Manuals will be available soon. (2014/10/4)
