Detailed Description

A metronome class which is like an EventDelay which retriggers itself when the delay time is up, to produce a repeating beat.

Metronome can be set() to a number of milliseconds, then after calling start(), ready() will return true when the time is up.
Alternatively, start(milliseconds) will call set() and start() together. This is called Metronome to avoid conflict with the Arduino Metro library.

Constructor & Destructor Documentation

Metronome()

Metronome::Metronome ( unsigned int  delay_milliseconds = 0 )

inline

Constructor.

Declare a Metronome object.

Parameters

delay_milliseconds

how long between each occasion when ready() returns true.

Definition at line 31 of file Metronome.h.

Member Function Documentation

ready()

bool Metronome::ready ( )

inline

Call this in updateControl() or updateAudio() to check if it is time for a beat.

Returns

true if the time for one is up.

Definition at line 75 of file Metronome.h.

set()

void EventDelay::set ( unsigned int  delay_milliseconds )

inlineinherited

Set the delay time.

This setting is persistent, until you change it by using set() again.

Parameters

delay_milliseconds

delay time in milliseconds.

Note

timing: 12us

Definition at line 40 of file EventDelay.h.

setBPM()

void Metronome::setBPM ( float  bpm )

inline

Set the beats per minute.

Parameters

bpm	beats per minute

Definition at line 63 of file Metronome.h.

start() [1/2]

void Metronome::start ( )

inline

Start the metronome.

Definition at line 40 of file Metronome.h.

start() [2/2]

void Metronome::start ( unsigned int  delay_milliseconds )

inline

Set the time between beats and start the metronome.

Parameters

delay_milliseconds

delay time in milliseconds.
