Detailed Description

Driver for Dectris merlin pixel array detectors using their Labview server over TCP/IP socket.

Constructor & Destructor Documentation

◆ merlinDetector()

merlinDetector::merlinDetector	(	const char *	portName,
		const char *	LabviewCommandPort,
		const char *	LabviewDataPort,
		int	maxSizeX,
		int	maxSizeY,
		int	detectorType,
		int	maxBuffers,
		size_t	maxMemory,
		int	priority,
		int	stackSize
	)

Constructor for merlin 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]	LabviewCommandPort	The name of the asyn port previously created with drvAsynIPPortConfigure to communicate with Labview.
[in]	LabviewDataPort	The name of the asyn port previously created with drvAsynIPPortConfigure to communicate with Labview.
[in]	maxSizeX	The size of the merlin detector in the X direction.
[in]	maxSizeY	The size of the merlin detector in the Y direction.
[in]	detectorType	The detector type (Marlin, MerlinXBPM, etc.)
[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

◆ fromLabViewStr()

void merlinDetector::fromLabViewStr ( const char * str )

◆ merlinStatus()

void merlinDetector::merlinStatus ( )

This thread periodically read the detector status (temperature, humidity, etc.) It does not run if we are acquiring data, to avoid polling Labview when taking data.

◆ merlinTask()

void merlinDetector::merlinTask ( )

This thread controls acquisition, reads image files to get the image data, and does the callbacks to send it to higher layers It is totally decoupled from the command thread and simply waits for data frames to be sent on the data channel (TCP) regardless of the state in the command thread and TCP channel.

◆ report()

void merlinDetector::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.

◆ toLabViewStr()

void merlinDetector::toLabViewStr ( const char * str )

◆ writeFloat64()

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

virtual

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

This function performs actions for some parameters, including ADAcquire, ADTriggerMode, 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.
