PlayTune

Purpose

Play a tune on the CrcDuino buzzer.

When to use

When you want to play a sound (for debugging).

Where to use

Inside the loop function.

Calling this function cancels the previous sound. Make sure to not call it repeatedly.

Returns

N/A

Main prototype and parameters

void CrcLib::PlayTune(const Note notes[], bool repeat)

The following parameters must be passed to the function for it to work properly:

A sequence of notes to play
Whether to loop the sound

Overloads

void CrcLib::PlayTune(Tune* tune)

A more advanced version of the function you probably don’t need. If you want to use it, read CrcBuzz.h for more info.

Examples

#include <CrcLib.h>

// See the page about Note
// Define a song using { <duration in ms>, <note frequency in Hz> }
Note notes[] = { { 250, NOTE_B4 }, { 500, NOTE_F5 }, Note::END };

CrcLib::Timer timer;
void setup() {
    CrcLib::Initialize();
    timer.Start(2000);
}

void loop() {
    CrcLib::Update();

    if (timer.IsFinished()) { // start the tune each 2s
        timer.Next();
        CrcLib::PlayTune(notes, false);
    }
}
