I am using the C-Style API to handle the C5 (and C6) camera from Automation Technology.
I wanted to add a mechanism to catch the AcquisitionEnd event, which occurs when the camera is triggered to deliver the image. However, I couldn’t see the timestamp associated with this event being updated in Common Vision Blox (or GenICam Browser), and I couldn’t catch it using the NRegisterUpdate callback available in iCVGenApi.h.
Am I doing something wrong? Do you have any advice on how to detect this event, or another one that could capture this camera stop caused by a trigger?
sorry for the late response. I just checked that events work fine in CVB. Please check that you activated (switched the event to on). Note that this is maybe not persistent after closing the device.
Furthermore you can check if the event is actually sent using wireshark,
Please contact our support de.support@stemmer-imaging.com if the problem persists
Aytoo, the C-style API point is the key detail here. Since events in CVB are typically not persistent after closing the device, make sure you explicitly switch AcquisitionEnd to on after every open and reconnect, not just once during setup. Also verify the trigger source is actually causing the camera to emit the event rather than only delivering frames. The Wireshark suggestion from the earlier reply is worth taking seriously, since it separates a device-side event from a host-side callback registration issue. If the event is confirmed on the wire but NRegisterUpdate still never fires, that narrows it to how the callback is bound.
