Fork of DebouncedInterrupt by Anil Kandangath

Example code:

#include "DebouncedInterrupt.h"

DebouncedInterrupt up_button(USER_BUTTON);

void onUp()
{
    // Do Something
}

int main()
{
    // Will immediatly call function and ignore other interrupts until timeout
    up_button.attach(&onUp, IRQ_FALL, 1000, true);

    // Will call function only if button has been held for the specified time
    //up_button.attach(&onUp, IRQ_FALL, 500, false);

    while(1) {}
}
