Sequence Functions

Sequence functions start and stop a continuous acquisition of multiple

frames.

imaq1394SetupSequenceImage Configuresand starts a session for

acquiring a full sequence into the

list of buffersmanaged by

IMAQVision.

imaq1394SetupSequence Configuresand starts a session for

acquiring a full sequence in the

bufferlist.

TriggerFunctions

Triggerfunctions controlthe triggermode ofthe IEEE-1394camera.

imaq1394TriggerConfigure Configuresan acquisition to start

based onan external trigger.

Miscellaneous Functions

Miscellaneous functions return information such as session status.

imaq1394Status Getsthe current session status.

Low-Level Functions

Use low-level functions when you require more direct control of the

acquisitionof the images.

Acquisition Functions

Use acquisition functions to configure, start, and abort an image

acquisition, or examine a buffer during an acquisition.

imaq1394ConfigureAcquisition Configuresthe acquisition

session mode (continuous or

one-shot).

imaq1394StartAcquisition Startsacquisition synchronously

or asynchronously.
