Timer

  1. Hello World!
  2. API

The Timer interface is used to create, start, stop and read a timer for measuring small times (between microseconds and seconds).

Any number of Timer objects can be created, and can be started and stopped independently

Warning

Note that timers are based on 32-bit int microsecond counters, so can only time up to a maximum of 2^31-1 microseconds i.e. 30 minutes. They are designed for times between microseconds and seconds. For longer times, you should consider the time()/Real time clock.

Hello World!

Simple timer example

#include "mbed.h"

Timer t;

int main() {
    t.start();
    printf("Hello World!\n");
    t.stop();
    printf("The time taken was %f seconds\n", t.read());
}
