A FlyCapture API Code Samples
A.1 Setting a GPIOPin to Strobe Using the FlyCapture API
The following FlyCapture code sample uses the C++ interface to do the following:
n Configures GPIO1 as the strobe output pin.
n Enables strobe output.
n Specifies an active high (rising edge) strobe signal.
n Specifies that the strobe signal begin 1 ms after the shutter opens.
n Specifies the duration of the strobe as 1.5 ms.
Assuming a Camera object cam:
StrobeControl mStrobe;
mStrobe.source = 1;
mStrobe.parameter = 0;
mStrobe.onOff = true;
mStrobe.polarity = 1;
mStrobe.delay = 1.0f;
mStrobe.duration = 1.5f
cam.SetStrobeControl(&mStrobe);
A.2 Setting a Standard Video Mode, Format and Frame Rate Using
the FlyCapture API
The following FlyCapture code snippet sets the camera to: 640x480 Y8 at 60 FPS.
Camera.SetVideoModeandFrameRate( VIDEOMODE_640x480Y8 , FRAMERATE_60 );
A.3 Asynchronous Hardware Triggering Using the FlyCapture API
The following FlyCapture code sample uses the C++ interface to do the following:
n Sets the trigger mode to Trigger Mode 0.
n Configures GPIO0 as the trigger input source.
n Enables triggered acquisition.
n Specifies the trigger signal polarity as an active high (rising edge) signal.
Assuming a Camera object cam:
TriggerMode mTrigger;
mTrigger.mode = 0;
mTrigger.source = 0;
mTrigger.parameter = 0;
mTrigger.onOff = true;
mTrigger.polarity = 1;
cam.SetTriggerMode(&mTrigger);
