Detailed Description

Wraps hardware connection for signal output to scanners, fast z control, and pockels cell with NI-DAQmx.

Constructor & Destructor Documentation

scope::OutputsDAQmxResonance::OutputsDAQmxResonance	(	const uint32_t &	_area,
		const parameters::OutputsDAQmxResonance &	_outputparams,
		const parameters::Scope &	_params
	)

Creates the task for scanner, pockels, and fast-z output with NI DAQmx.

Configure sample timings for output tasks. With DaqTiming ReferenceClock both tasks use the onboard oscillator (empty timing source string) which is synchronized to the PXI 10MHz backplane clock used as reference clock. Read http://www.ni.com/white-paper/3615/en, "M Series Synchronization with LabVIEW and NI-DAQmx" at NI Developer Zone.
Configures the triggering for the output tasks. Since all output&input tasks have to start synchronously, the start trigger for all is the /ao/StartTrigger signal of the first area's analog output task

Member Function Documentation

void scope::OutputsDAQmxResonance::Start ( void  )

overridevirtual

Start task, last the first output task (all other are waiting for it as their start trigger).

Reimplemented from scope::Outputs.

Definition at line 69 of file OutputsDAQmxResonance.cpp.

void scope::OutputsDAQmxResonance::Stop ( void  )

overridevirtual

Stop task.

Reimplemented from scope::Outputs.

Definition at line 74 of file OutputsDAQmxResonance.cpp.

int32_t scope::OutputsDAQmxResonance::Write ( const std::vector< int16_t > &  _xyzp, const uint32_t &  _blocks = 1  )

overridevirtual

Writes values for one frame of X-Y-fastZ and pockels data to the device buffer.

Use several WriteAnalogI16 commands with small parts (blocks) of the whole ScannerVectorFrame to speed up the update (do not have to wait until the complete buffer is empty/ready for writing into).

Parameters

[in]	_xyzp	the scannervector with xyzp data to write to device
[in]	_reszoomfactor	the factor for zooming in resonance scanner mode
[in]	_blocks	in how many blocks should the scannervector be written (more blocks faster update, since smaller blocksize -> buffer for this is free earlier), see "DAQmx quick buffer update.vi"

Reimplemented from scope::Outputs.
