Detailed Description

Wraps an FPGA that does two area demultiplexing and analog integration with the NI 5771 FlexRio adapter module on the NI 7962R FPGA.

Definition at line 18 of file FPGAAnalogDemultiplexer.h.

Constructor & Destructor Documentation

scope::FPGAAnalogDemultiplexer::FPGAAnalogDemultiplexer ( )

Load the FPGA bitfile, set the IO module's onboard clock and initialize the acquisition.

Definition at line 8 of file FPGAAnalogDemultiplexer.cpp.

scope::FPGAAnalogDemultiplexer::~FPGAAnalogDemultiplexer ( void )

Close FPGA session.

Definition at line 47 of file FPGAAnalogDemultiplexer.cpp.

Member Function Documentation

void scope::FPGAAnalogDemultiplexer::Initialize ( parameters::InputsFPGA * _parameters )

overridevirtual

Set initial parameters.

Derived classes override this and cast _parameters to the appropriate derived type. Derived functions should check if already initialized.

Reimplemented from scope::FPGAInterface.

Definition at line 53 of file FPGAAnalogDemultiplexer.cpp.

double scope::FPGAAnalogDemultiplexer::SetPixeltime	(	const uint32_t &	_area,
		const double &	_pixeltime
	)

overridevirtual

Sets the time per pixel/dwell time (in seconds)

Parameters

[in]	_area	for which area
[in]	_pixeltime	the pixel dwell time in seconds

Returns: the actual pixel dwell time, can be different than requested due to finite clock rate

Reimplemented from scope::FPGAInterface.

Definition at line 63 of file FPGAAnalogDemultiplexer.cpp.

double scope::FPGAAnalogDemultiplexer::SetLinetime	(	const uint32_t &	_area,
		const double &	_linetime
	)

overridevirtual

Sets the time per line (in seconds) for the generation of the line clock (if implemented)

Parameters

[in]	_area	for which area
[in]	_linetime	the line time in seconds

Returns: the actual line time, can be different than requested due to finite clock rate

Reimplemented from scope::FPGAInterface.

Definition at line 80 of file FPGAAnalogDemultiplexer.cpp.

void scope::FPGAAnalogDemultiplexer::SetTriggering ( const bool & _waitfortrigger )

overridevirtual

Sets if the FPGA should wait for a trigger before starting acquisition.

Parameters

[in] _waitfortrigger true if wait for trigger

Reimplemented from scope::FPGAInterface.

Definition at line 85 of file FPGAAnalogDemultiplexer.cpp.

void scope::FPGAAnalogDemultiplexer::SetContinuousAcquisition ( const bool & _cont )

overridevirtual

Sets if the FPGA should acquire data continuously or acquire the number of pixels per channel set with SetRequestedPixels.

Parameters

[in] _cont yes or no

Reimplemented from scope::FPGAInterface.

Definition at line 89 of file FPGAAnalogDemultiplexer.cpp.

void scope::FPGAAnalogDemultiplexer::SetRequestedPixels	(	const uint32_t &	_area,
		const uint32_t &	_reqpixels
	)

overridevirtual

Sets the number of pixels per channel the FPGA should acquire, set to -1 for live scanning.

Parameters

[in]	_area	for which area
[in]	_reqpixels	number of pixels the FPGA should acquire before automatically stopping acquisition

Reimplemented from scope::FPGAInterface.

Definition at line 93 of file FPGAAnalogDemultiplexer.cpp.

void scope::FPGAAnalogDemultiplexer::StartAcquisition ( )

overridevirtual

Starts the acquisition on the FPGA.

Reimplemented from scope::FPGAInterface.

Definition at line 98 of file FPGAAnalogDemultiplexer.cpp.

void scope::FPGAAnalogDemultiplexer::StopAcquisition ( )

overridevirtual

Stops the acquisition on the FPGA.

Reimplemented from scope::FPGAInterface.

Definition at line 110 of file FPGAAnalogDemultiplexer.cpp.

int32_t scope::FPGAAnalogDemultiplexer::ReadPixels	(	DaqChunk &	_chunk,
		const double &	_timeout,
		bool &	_timedout
	)

overridevirtual

Read only pixels from the FPGA FIFO.

Parameters

[in,out]	_chunk	the daq chunk to read into, inside _chunk is information about the area for wich to retrieve, the number of pixels per channel to read, and the number of channels
[in]	_timeout	time out for reading in seconds
[out]	_timedout	set to true if reading timed out
