NI-DAQmx introduces the concept of a sample timing type. Each sample timing type is a different stimulus for triggering the action of producing a sample. When you select a Timing function/VI, you select your sample timing type. There also is an attribute/property for setting the following sample timing types:
Programmatically, you include the Change Detection Timing function/VI, specifying the physical channels for rising and falling edges on which to detect changes. You can query for an overflow by using the Overflow attribute/property in your application after the task starts.
There are separate Burst Handshake Timing functions/VIs based on whether you import or export a sample clock. Using the appropriate function/VI is important because there are timing restrictions (such as setup and hold times) when sharing a clock between the two devices.
