DAQmx Trigger Start on digital value

Status: New

It would be helpful to add an option like "Digital Value" in the DAQmx Trigger.vi (comparable to Analog Window).
Background: when missing the edge of a digital trigger signal (due to being late in code execution after eg. waveform reconfiguration), the trigger event does not happen. With this new option it is possible to execute the trg event asap after missing the edge.

+1. The "Digital Value" trigger seems like a useful, but perhaps niche feature. It also might be quite difficult to implement.

You might be able to implement a workaround by refactoring your code, and potentially adding logic to check the state of the digital input before and after the waveform reconfiguration.

 

This idea is probably best suited to the Data Acquisition Idea Exchange.
