You can set this sample in
wxPropView
(p.
). E.g. the sensor makes 22.7 frames per second in
Continuous
Mode
(p.
). This means that the sensor needs 44 ms to output the complete image.
1
--------- = approx. 44 ms
22.7
We take 55 ms to be sure. Now, as different exposure times we take 1 ms (
Timer1
) and 5 ms (
Timer2
). To get the
55 ms, we have to add 54000 us (
Counter1
) and 50000 us (
Counter2
).
Finally, you have to set the logic gate as shown in the figure:
Figure 2: wxPropView - Logic gate setting
Note
Because there are 4 counters and 2 timers you can only add one further exposure time using one counter
as a timer.
So if you want other sequences, you have to use the counters and timers in a flexible way as show in the next
sample:
