PTP synchronization with multiple cameras about pylon-ros-camera

[ctyfang]

From the user manual, it appears that you can check the synchronization offset from the master clock with some API commands.

"1. Make sure that PTP clock synchronization has been enabled on all devices (see Section 8.8.1on page 268).

2. Execute the GevIEEE1588DataSetLatch command to take a snapshot of the camera’s current PTP clock synchronization status.
3. Read one or more of the following parameter values from the device:
   GevIEEE1588OffsetFromMaster
   GevIEEE1588ClockId
   GevIEEE1588ParentClockId
   GevIEEE1588StatusLatched

All of these parameter values relate to exactly the same point in time, i.e. the point in time when the device received the GevIEEE1588Latch command"

Hello

The ROS2 pylon driver v1.1.0 gives now access through services to PTP related parameters and commands, allowing to enable PTP synchronization, to issue scheduled or not action commands, to use the periodic signal camera feature for ACE2 and the synchronous free-run feature for ACE1.
I am thus closing this issue.

Hello,

I am sorry that currently we may not address this topic for the Pylon ROS driver in a short time due to our resources limit. Anyway we keep it open. If someone wants to contribute in this topic it will be very welcomed!

Thanks!
