Detailed Description

Driver for Princeton Instruments cameras using the LightField Automation software.

Constructor & Destructor Documentation

◆ LightField()

LightField::LightField	(	const char *	portName,
		const char *	experimentName,
		int	maxBuffers,
		size_t	maxMemory,
		int	priority,
		int	stackSize
	)

Constructor for LightField driver; most parameters are simply passed to ADDriver::ADDriver.

After calling the base class constructor this method creates a thread to collect the detector data, and sets reasonable default values for the parameters defined in this class, asynNDArrayDriver and ADDriver.

Parameters

[in]	portName	The name of the asyn port driver to be created.
[in]	experimentName	The name of the experiment to open initially. Set this to an empty string to open the default experiment in LightField.
[in]	maxBuffers	The maximum number of NDArray buffers that the NDArrayPool for this driver is allowed to allocate. Set this to -1 to allow an unlimited number of buffers.
[in]	maxMemory	The maximum amount of memory that the NDArrayPool for this driver is allowed to allocate. Set this to -1 to allow an unlimited amount of memory.
[in]	priority	The thread priority for the asyn port driver thread if ASYN_CANBLOCK is set in asynFlags.
[in]	stackSize	The stack size for the asyn port driver thread if ASYN_CANBLOCK is set in asynFlags.

Member Function Documentation

◆ exitHandler()

void LightField::exitHandler ( void * args )

◆ frameCallback()

void LightField::frameCallback ( ImageDataSetReceivedEventArgs^ args )

callback function that is called by XISL every frame at end of data transfer

◆ pollerTask()

void LightField::pollerTask ( )

◆ readEnum()

asynStatus LightField::readEnum	(	asynUser *	pasynUser,
		char *	strings[],
		int	values[],
		int	severities[],
		size_t	nElements,
		size_t *	nIn
	)

virtual

◆ report()

void LightField::report	(	FILE *	fp,
		int	details
	)

virtual

Report status of the driver.

Prints details about the driver if details>0. It then calls the ADDriver::report() method.

Parameters

[in]	fp	File pointed passed by caller where the output is written to.
[in]	details	If >0 then driver details are printed.

Reimplemented from asynNDArrayDriver.

◆ setAcquisitionComplete()

void LightField::setAcquisitionComplete ( )

◆ setShutter()

void LightField::setShutter ( int open )

virtual

Set the shutter position.

This method will open (1) or close (0) the shutter if ADShutterMode==ADShutterModeEPICS. Drivers will implement setShutter if they support ADShutterModeDetector. If ADShutterMode=ADShutterModeDetector they will control the shutter directly, else they will call this method.

Parameters

[in] open 1 (open) or 0 (closed)

Reimplemented from ADDriver.

◆ settingChangedCallback()

void LightField::settingChangedCallback ( SettingChangedEventArgs^ args )

◆ writeFloat64()

asynStatus LightField::writeFloat64	(	asynUser *	pasynUser,
		epicsFloat64	value
	)

virtual

Called when asyn clients call pasynFloat64->write().

This function performs actions for some parameters, including ADAcquireTime, ADGain, etc. For all parameters it sets the value in the parameter library and calls any registered callbacks..

Parameters

[in]	pasynUser	pasynUser structure that encodes the reason and address.
[in]	value	Value to write.

◆ writeInt32()

asynStatus LightField::writeInt32	(	asynUser *	pasynUser,
		epicsInt32	value
	)

virtual

Called when asyn clients call pasynInt32->write().

This function performs actions for some parameters, including ADAcquire, ADBinX, etc. For all parameters it sets the value in the parameter library and calls any registered callbacks..

Parameters

[in]	pasynUser	pasynUser structure that encodes the reason and address.
[in]	value	Value to write.

Reimplemented from ADDriver.

◆ writeOctet()

asynStatus LightField::writeOctet	(	asynUser *	pasynUser,
		const char *	value,
		size_t	nChars,
		size_t *	nActual
	)

virtual

Called when asyn clients call pasynOctet->write().

This function performs actions for some parameters, including NDAttributesFile. For all parameters it sets the value in the parameter library and calls any registered callbacks..

Parameters

[in]	pasynUser	pasynUser structure that encodes the reason and address.
[in]	value	Address of the string to write.
[in]	nChars	Number of characters to write.
[out]	nActual	Number of characters actually written.

Reimplemented from asynNDArrayDriver.
