Applying Trigger Signals
The paragraphs above mention "applying a trigger signal". There are two ways to apply an
acquisition start or a frame start trigger signal to the camera: via software or via hardware.
To apply trigger signals via software, you must first select the acquisition start or the frame start
trigger and then indicate that software will be used as the source for the selected trigger signal. At
that point, the Basler pylon API or direct camera register access can be used to apply a software
trigger signal to the camera for the selected trigger.
To apply trigger signals via hardware, you must first select the acquisition start or the frame start
trigger. You then configure the camera’s GPIO as an input and select the input to be used as the
source for the selected trigger. At that point, each time the proper electrical signal is applied to the
selected input, an occurrence of the selected trigger signal will be recognized by the camera.
