Detailed Description

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

X/Pockels use a pixel clock and Y/Z use a different, a line clock. So you need to NI cards to get this working (since one card can only run one output task with only one clock.

Member Function Documentation

void scope::OutputsDAQmxLineClock::Start ( void  )

overridevirtual

Start task.

Reimplemented from scope::Outputs.

Definition at line 71 of file OutputsDAQmxLineClock.cpp.

void scope::OutputsDAQmxLineClock::Stop ( void  )

overridevirtual

Stops task.

Reimplemented from scope::Outputs.

Definition at line 77 of file OutputsDAQmxLineClock.cpp.

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

overridevirtual

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

Depending on the implementation in the derived classes, this _xyzp can be a complete frame or e.g. only one x line (for x and p), one y column (for y and fast z) , which are then repeated by the device.

Parameters

[in]	_xyzp	the scannervector with xyzp data to write to device
[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.
