void scope::FPGANoiseOutput::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 48 of file FPGANoiseOutput.cpp.

double scope::FPGANoiseOutput::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 55 of file FPGANoiseOutput.cpp.

double scope::FPGANoiseOutput::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 65 of file FPGANoiseOutput.cpp.

void scope::FPGANoiseOutput::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 75 of file FPGANoiseOutput.cpp.

void scope::FPGANoiseOutput::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 79 of file FPGANoiseOutput.cpp.

void scope::FPGANoiseOutput::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 83 of file FPGANoiseOutput.cpp.

void scope::FPGANoiseOutput::StartAcquisition ( )

overridevirtual

Starts the acquisition on the FPGA.

Reimplemented from scope::FPGAInterface.

Definition at line 87 of file FPGANoiseOutput.cpp.

void scope::FPGANoiseOutput::StopAcquisition ( )

overridevirtual

Stops the acquisition on the FPGA.

Reimplemented from scope::FPGAInterface.

Definition at line 126 of file FPGANoiseOutput.cpp.

int32_t scope::FPGANoiseOutput::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

Returns: number of read pixels per channel or -1 on error

Precondition: _channels > 0 && _channels <= 2

Implements scope::FPGAInterface.

Definition at line 92 of file FPGANoiseOutput.cpp.

void scope::FPGANoiseOutput::CheckFPGADiagnosis ( )

Checks the status of the FIFOs on the FPGA.

Definition at line 130 of file FPGANoiseOutput.cpp.

void scope::FPGANoiseOutput::ClearFIFOs ( )

Clears the interloop and ToHost FIFOs.

Definition at line 144 of file FPGANoiseOutput.cpp.
