Detailed Description

Triggered Scope that it can be set to start on a rising or falling signal.

This makes it extremely useful for very zoomed-in waveform viewing.

Constructor & Destructor Documentation

TriggeredScope()

TriggeredScope::TriggeredScope

(

AudioFifo &

)

Creates a Triggered scope.

Pass a fifo to read from

~TriggeredScope()

TriggeredScope::~TriggeredScope ( )

override

Destructor.

Member Function Documentation

setNumChannels()

void TriggeredScope::setNumChannels

(

int

num

)

setNumSamplesPerPixel()

void TriggeredScope::setNumSamplesPerPixel

(

float

newNumSamplesPerPixel

)

Sets the number of samples represented by each pixel on the scope.

Setting this to a low number will give a very zoomed in display, a high number zoom out.

setVerticalZoomFactor()

void TriggeredScope::setVerticalZoomFactor

(

float

newVerticalZoomFactor

)

Sets the vertical zoom factor of the display.

setVerticalZoomOffset()

void TriggeredScope::setVerticalZoomOffset	(	float	newVerticalZoomOffset,
		int	ch )

Sets the vertical zoom offset of the display.

setSingleTrigger()

void TriggeredScope::setSingleTrigger

(

bool

singleTrigger_

)

Enable single trigger mode - will pause when trigger is found.

hasTriggered()

bool TriggeredScope::hasTriggered

(

)

const

Check if single trigger mode has triggered (and is now paused).

setPaused() [1/2]

void TriggeredScope::setPaused

(

bool

shouldBePaused

)

Pause/unpause the scope display.

setPaused() [2/2]

void TriggeredScope::setPaused	(	bool	shouldBePaused,
		int	lockTriggerPoint )

resetTrigger()

void TriggeredScope::resetTrigger

(

)

Reset/unpause after single trigger.

isPaused()

bool TriggeredScope::isPaused

(

)

const

Check if scope is paused.

setTriggerMode()

void TriggeredScope::setTriggerMode

(

TriggerMode

newTriggerMode

)

Sets the type of change that will trigger a trace.

setTriggerChannel()

void TriggeredScope::setTriggerChannel

(

int

ch

)

Set channel to trigger on, -1 ave of all channels.

setTriggerLevel()

void TriggeredScope::setTriggerLevel

(

float

l

)

Set level to trigger on.

setTriggerPos()

void TriggeredScope::setTriggerPos

(

float

l

)

setDrawTriggerPos()

void TriggeredScope::setDrawTriggerPos

(

bool

d

)

setDrawCursorInfo()

void TriggeredScope::setDrawCursorInfo

(

bool

d

)

Enable/disable cursor readout showing level and time at mouse position.

setSampleRate()

void TriggeredScope::setSampleRate

(

double

sr

)

Set sample rate for time display.

setBeatSync()

void TriggeredScope::setBeatSync

(

int

beats

)

Set beat sync mode - 0 = off, otherwise number of beats to sync to.

setPlayheadSource()

void TriggeredScope::setPlayheadSource

(

std::function< std::tuple< double, double, bool >()>

source

)

Set a function to retrieve playhead info - called from timer.

updatePlayhead()

void TriggeredScope::updatePlayhead	(	double	ppqPosition,
		double	bpm,
		bool	isPlaying )

Call this from processBlock to update playhead position.

paint()

override

timerCallback()

void TriggeredScope::timerCallback ( )

override

mouseMove()

void TriggeredScope::mouseMove ( const juce::MouseEvent & e )

override

mouseDown()

void TriggeredScope::mouseDown ( const juce::MouseEvent & e )

override

mouseDrag()

override

mouseExit()

void TriggeredScope::mouseExit ( const juce::MouseEvent & e )

override
