oak-d-s2 poe FSYNC syncing

walawala111

Hello all,
I am testing the FSYNC syncing of the Oak-D-S2 POE camera, but I found that the camera takes a photo at both the rising and falling edges. Is there any way to set the camera to trigger the photo at the rising or falling edge?
left.initialControl.setExternalTrigger(1, 0) right.initialControl.setExternalTrigger(1, 0) left.setResolution(dai.MonoCameraProperties.SensorResolution.THE_800_P) left.setFps(60) right.setResolution(dai.MonoCameraProperties.SensorResolution.THE_800_P) right.setFps(60)
I am using a 12V power supply to power the M8 port.
Thanks

What is the pulse width when you trigger the capture?

I manually power on and off, so the time interval for power on and off is around 500ms-1s

I'm thinking it's probably that pulses are noisy causing the camera to trigger twice. By design, it should only trigger on rising edge.

Is there any way to reduce the impact of pulse noise?

Shorten the cables, use a function generator instead of DC supply, make sure the rise time/fall time is as short as possible.
Would be nice if you could check the signal you are generating with an oscilloscope to sanity check.

Thanks,
