Future Time Events in Event Structure

Status: New

Not sure if this should be in another category, but here is the idea.

 

In DAQmx you  can register for events like Change Detection Event, Sample Complete Event, etc. These events occur in the Event structure.

 

Idea: Extend this capability to NI-Sync.

For example allow a future time event to occur in an event structure, instead of firing a TTL pulse. The steps would be:

1. Create a new NI-Sync instrument driver session;
2. Read the current time of the clock;
3. Define when the event will be generated by introducing a delay to the current 1588 time;
4. Program when the event will occur at the specified time;
5. Register for Event
6. Event Occurs - do something.
7. Clean Up

See below for diagram.
