Public Member Functions
virtual void	addNotifyAudioChange (AudioInfoSupport &bi)
	Adds target to be notified about audio changes.

virtual AudioInfo	audioInfo () override
	provides the actual input AudioInfo

virtual AudioInfo	audioInfoOut ()
	provides the actual output AudioInfo: this is usually the same as audioInfo() unless we use a transforming stream

int	availableForWrite () override

bool	begin ()

virtual bool	begin (AudioInfo info)

bool	begin (PWMConfig config)
	starts the processing using Streams

virtual void	clearNotifyAudioChange ()
	Deletes all change notify subscriptions.

PWMConfig	config ()

virtual PWMConfig	defaultConfig (RxTxMode mode=TX_MODE)

PWMDriver *	driver ()
	Provides access to the driver.

virtual void	end () override

virtual void	flush ()

uint32_t	framesPerSecond ()

virtual bool	isDeletable ()
	If true we need to release the related memory in the destructor.

bool	isNotifyActive ()
	Checks if the automatic AudioInfo update is active.

virtual	operator bool ()

virtual bool	removeNotifyAudioChange (AudioInfoSupport &bi)
	Removes a target in order not to be notified about audio changes.

virtual void	setAudioInfo (AudioInfo info)
	updates the sample rate dynamically

void	setBuffer (BaseBuffer< uint8_t > *buffer)

void	setNotifyActive (bool flag)
	Deactivate/Reactivate automatic AudioInfo updates: (default is active)

Detailed Description

Common functionality for PWM output. Please use the PWMAudioOutput typedef instead which references the implementation.

Member Function Documentation

void setBuffer ( BaseBuffer< uint8_t > * buffer )

inline

You can assign your own custom buffer impelementation: must be allocated on the heap and will be cleaned up by this class

virtual void writeSilence ( size_t len )

inlinevirtualinherited

Writes n 0 values (= silence)

Parameters

len
