Create Capture Waveform (Create Capture Waveform (Serial)) (G Dataflow)

Version:
Last Modified: September 14, 2017

Sets the capture waveform settings for serial acquisition. Settings apply across all sites if multiple sites are configured in the pin map. You cannot reconfigure settings after waveforms are created.

datatype_icon

waveform name

Waveform name to use from the file.

You must specify waveform name if the file contains multiple waveforms.

Use the waveform name with the capture_start opcode in your pattern.

datatype_icon

session in

Instrument session obtained from the niDigital Initialize with Options node.

datatype_icon

pin list

List of capture pins from the waveform.

The pin list must match the capture pins in the pattern that references the waveform. The pin order in the pin list determines the bit positions of the data captured by the niDigital Fetch Capture Waveform node.

datatype_icon

sample width

Width in bits of each serial sample. Valid values are between 1 and 32.

datatype_icon

bit order

Order in which to shift the bits.

Name Value Description
MSB first 2500 Specifies the bit order by most significant bit first.
LSB first 2501 Specifies the bit order by least significant bit.

Default: MSB First

datatype_icon

error in

Error conditions that occur before this node runs.

The node responds to this input according to standard error behavior.

Standard Error Behavior

Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

error in does not contain an error error in contains an error
If no error occurred before the node runs, the node begins execution normally.

If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

Default: No error

datatype_icon

session out

Handle that identifies the session in all subsequent NI-Digital node calls.

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.

Where This Node Can Run:

Desktop OS: Windows

FPGA: Not supported

Web Server: Not supported in VIs that run in a web application
