Programming The Acquisition; Start Timer - Matrix Vision mvBlueLYNX-X Technical Manual

For the master camera, there are to possiblities how it is triggered:
1. The master camera triggers itself logically (so called Master - Slave, see figure 147), or
2. the master camera uses the external trigger signal, which was created by itself, via digital input (so
called Slave - Slave, see figure 148).
With Master - Slave and according to the delay of the opto-isolated inputs of the slave cameras, you
have to adapted the property Trigger delay of the master camera to synchronize the cameras exactly.
As you can see in figure 147 and figure 148 you will need a dropping resistor of 2 kOhm, because the
opto-isolated inputs of the mvBlueFOX-MLC are not designed for high voltages (12 .. 24V).

20.7.3 Programming the acquisition

You will need two timers and you have to set a trigger.

20.7.3.1 Start timer

Two timers are used for the "start timer". Timer1 defines the interval between two triggers. Timer2 generates
the trigger pulse at the end of Timer1.
The following sample shows a trigger
1. which is generated every second and
2. the pulse width is 10 ms:
#include <mvIMPACT_CPP/mvIMPACT_acquire.h>
#include <mvIMPACT_CPP/mvIMPACT_acquire_GenICam.h>
