Profiler

Easily profile your Arduino functions (or even just a few lines of code) to see how much time they take. The output can be disabled and enabled at any time. Very lightweight.

#include <Profiler.h>

#define   DEBUG_LED   13

// Example function that will be profiled including debug pin output:
//
void foo() {
    profiler_t profiler(DEBUG_LED);

    delay(1000);
}

// Example function where only part of the code
// will be profiled using a temporary scope
//
void bar() {
    // this code will not be profiled.
    // yes the code is pointless heh
    for (int i=0; i < 10; i++) {
        delay(100);
    }

    // create a temporary scope just to contain the instantiation of a profiler_t
    // object in order to time a smaller section of code inside a larger section
    {
        profiler_t profiler;

        delay(500);
    }

    // more pointless code that will not be profiled
    for (int i=0; i < 10; i++) {
        delay(100);
    }
}

void setup() {
    Serial.begin(115200);
    while (!Serial);

    foo();

    bar();
}

void loop() { }

output:

Time spent: 999
