6.3.2 Acquisition Status
If a camera receives a software line start trigger signal when it is not in a "waiting for line start
trigger" acquisition status, it will simply ignore the trigger signal.
The camera’s acquisition status indicator gives you the ability to check whether the camera is in a
"waiting for line start trigger" acquisition status. If you check the acquisition status before you apply
each software line start trigger signal, you can avoid applying trigger signals to the camera that will
be ignored.
The acquisition status indicator is designed for use when you are using host control of image
acquisition, i.e., when you are using software line start trigger signals.
To determine the acquisition status of the camera via the Basler pylon API:
Use the Acquisition Status Selector to select the Line Trigger Wait status.
Read the value of the Acquisition Status parameter.
If the value is set to "false", the camera is not waiting for the trigger signal.
If the value is set to "true", the camera is waiting for the trigger signal.
Checking the Acquisition Status Using Basler pylon
To determine the acquisition status of the camera via the Basler pylon API:
Use the Acquisition Status Selector to select the Line Trigger Wait status.
Read the value of the Acquisition Status parameter.
If the value is set to "false", the camera is not waiting for the trigger signal.
If the value is set to "true", the camera is waiting for the trigger signal.
You can check the acquisition status from within your application software by using the Basler pylon
API. The following code snippet illustrates using the API to check the acquisition status:
