Details
If this is true, an event was ignored because the event detector was already in the detected state
when the event occurred.
This is an indication of the state of the event detector built into the line itself. It does not indicate if an
overrun occurred in any other part of the trigger model or in any other detector that is monitoring the
event.
Example
overrun = digio.trigger[1].overrun
print(overrun)
If there is no trigger overrun, the following
text is output:
false

Digital I/O trigger line (1 to 14)
Details
Setting the pulse width to zero (0) seconds asserts the trigger indefinitely. To release the trigger line,
use digio.trigger[N].release().
Example
digio.trigger[4].pulsewidth = 20e-6
Sets the pulse width for trigger line 4 to
20 μs.
