Member Enumeration Documentation

State

enum Graph::TriggerDetector::State

Internal trigger state.

Enumerator
Armed	Trigger armed. The received data are are analyzed for the trigger condition.
Fired	Trigger fired. The trigger condition was detected. The trigger remains in this state, until the extrema buffer is filled and the data can be displayed.
