GMSL Multi-Camera Synchronization

This example starts two GMSL-connected Gemini 330 Series cameras in hardware synchronization mode. It uses the package's standard gemini_330_series.launch.py file.

Before starting the cameras, grant access to the camera synchronization device:

sudo chmod 777 /dev/camsync

Before starting the example, update the usb_port values in multi_gmsl_camera_synced.launch.py if your system reports different GMSL links. The default values are gmsl2-1 and gmsl2-3.

ros2 launch orbbec_camera multi_gmsl_camera_synced.launch.py

Both cameras use secondary_synced mode. camera_01 enables the host-side GMSL trigger at 30 fps (gmsl_trigger_fps=3000), while camera_02 receives the same trigger. The receiving camera is started first, followed by the trigger-generating camera after two seconds.
