Figure 1: wxPropView - Configuring Digital Input Debounce Times
Each digital input (LineMode equals Input) that can be selected via the LineSelector property will offer its own
property to configure the debouncing time for falling edge trigger signals ("mv Line Debounce Time Falling Edge")
and rising edge ("mv Line Debounce Time Rising Edge") trigger signals.
The line debounce time can be configured in micro-seconds with a maximum value of up to 5000 micro-seconds.
Internally each time an edge is detected at the corresponding digital input a timer will start (orange ∗ in figure 2 and
3), that is reset whenever the signal applied to the input falls below the threshold again. Only if the signal stays at
a constant level for a full period of the defined mvLineDebounceTime the input signal will be considered as a valid
trigger signal.
Note
Of course this mechanism delays the image acquisition by the debounce time.
