6.4.1.3 Setting The Frame Start Trigger Mode and Related Parameters
You can set the Trigger Mode and related parameter values for the frame start trigger from within
your application software by using the Basler pylon API. If your settings make it necessary, you can
also set the Trigger Source parameter.
The following code snippet illustrates using the API to set the Trigger Mode for the frame start
trigger to on and the Trigger Source to input line Line 1:
// Select the frame start trigger
camera.TriggerSelector.SetValue(TriggerSelector_FrameStart);
// Set the trigger mode for the selected trigger
camera.TriggerMode.SetValue(TriggerMode_On);
// Set the source for the selected trigger
camera.TriggerSource.SetValue(TriggerSource_Line1);
The following code snippet illustrates using the API to set the Acquisition Mode to continuous, the
Trigger Mode to off, and the Acquisition Frame Rate to 60:
// Set the acquisition mode to continuous frame
camera.AcquisitionMode.SetValue(AcquisitionMode_Continuous);
// Select the frame start trigger
camera.TriggerSelector.SetValue(TriggerSelector_FrameStart);
// Set the mode for the selected trigger
Camera.TriggerMode.SetValue( TriggerMode_Off );
// Set the exposure time
Camera.ExposureTime.SetValue( 3000.0 );
// Enable the acquisition frame rate parameter and set the frame rate. (Enabling
// the acquisition frame rate parameter allows the camera to control the frame
// rate internally.)
camera.AcquisitionFrameRateEnable.SetValue(true);
camera.AcquisitionFrameRate.SetValue(60.0);
// Start frame capture
Camera.AcquisitionStart.Execute( );
You can also use the Basler pylon Viewer application to easily set the parameters.
For more information about the pylon API and the pylon Viewer, see Section 3.1 on page 37.
