Details
This function pauses for up to timeout seconds for an input trigger. If one or more trigger events are detected
since the last time digio.trigger[N].wait() or digio.trigger[N].clear() was called, this function
returns a value immediately. After waiting for a trigger with this function, the event detector is automatically reset
and ready to detect the next trigger. This is true regardless of the number of events detected.
Example
digio.line[4].mode = digio.MODE_TRIGGER_OUT
triggered = trigger.digin[4].wait(3)
print(triggered)
Waits up to three seconds for a trigger to be
detected on trigger line 4, then outputs the
results.
Output if no trigger is detected:
false
Output if a trigger is detected:
true
