Detailed Description

Wraps hardware connection for signal input from PMTs using an NI FPGA.

Keep in mind to start the FPGA last, since it provides the sample clock for all other tasks.

Constructor & Destructor Documentation

scope::InputsFPGA::InputsFPGA ( const InputsFPGA &  i )

private

disable copy

scope::InputsFPGA::InputsFPGA	(	const uint32_t &	_area,
		parameters::InputsFPGA *	_inputparams,
		const parameters::Scope &	_params
	)

Postcondition

_params.areas[a].daq.pixeltime is set to the pixeltime coerced by the FPGA. Since the FPGA provides the sample clock for the DAQmx output via PXI_Trig1, this is merely cosmetic.

void scope::InputsFPGA::Start ( )

overridevirtual

Start task.

Implements scope::Inputs.

Definition at line 73 of file InputsFPGA.cpp.

void scope::InputsFPGA::Stop ( )

overridevirtual

Stops task.

Implements scope::Inputs.

int32_t scope::InputsFPGA::Read ( DaqChunk &  _chunk, bool &  _timedout, const double &  _timeout  )

overridevirtual

Reads one chunk of samples for one area.

Parameters

[in,out]	_chunk	chunk to fill with the read data
[out]	_timedout	true if read timed out
[in]	_timeout	timeout in seconds after which to return even if not enough samples were read

Returns

the number of samples per channel actually read
