Allow one-shot triggering system for plots
In certain situations we are not interested in the visualization of a continuous stream of real-time data. Rather, a full resolution snapshot of short event is desirable.
VILLASweb should have an option to lock/unlock plots after this acquisition has taken place.
The feature also requires changes in VILLASnode where we would need to monitor the trigger condition and only forward sample data to VILLASweb in case the trigger condition was fulfilled. VILLASnode is basically applying a windowing function onto our sample stream. We only let some samples through for a short acquisition period once a trigger condition has been fulfilled.
- How do we define the trigger condition?
- How do we inform VILLASweb about the trigger event?
