Arduino Interrupts

MsTimer2 is a small and very easy to use library to interface Timer2 with humans. It's called MsTimer2 because it "hardcodes" a resolution of 1 millisecond on timer2.
UPDATED:

• works on ATmega1280 (thanks to Manuel Negri).
• works on ATmega328 (thanks Jerome Despatis).
• works on ATmega48/88/168 and ATmega128/8.

Methods

MsTimer2::set(unsigned long ms, void (*f)())

this function sets a time on ms for the overflow. Each overflow, "f" will be called. "f" has to be declared void with no parameters.

MsTimer2::start()

enables the interrupt.

MsTimer2::stop()

disables the interrupt.

Ready, examples are already in default,in the ide

 

Example

// Toggle LED on pin 13 each second
#include 

void flash() {
  static boolean output = HIGH;

  digitalWrite(13, output);
  output = !output;
}

void setup() {
  pinMode(13, OUTPUT);

  MsTimer2::set(500, flash); // 500ms period
  MsTimer2::start();
}

void loop() {
}
