Help with PWM Trigger

[Vinicius Juvinski]

Hi Guys,

I'm using 2 GitUp 2 cameras on my drone and I'm having a trigger issue.
To demonstrate the problem I take this video - https://drive.google.com/open?id=0B1omx8hPUswTRnJiSFc4WjI3bm8
I made a arduino sketch to trigger 100 picures every 3 seconds, but in the end of time I got 84 or 85 pictures on each camera(the number of pictures is random - sometimes more, some time less).
I tried to increase the PWM pulse, PWM dutty, but I never got all pictures taked.

Thanks a lot

"trigger 100 picures every 3 seconds,"
So the total time for 100 photos is 300 seconds (5 minutes)?

If you are recording raw photos then 3 seconds may not be enough in all cases, sometimes it will take a little extra time to find space on the memory card.

If you have both cameras connected to the same signal, does it work with only 1 camera connected?

Hi Nigel,

how are you?
I have a few scenarios.
2 Arduino skects
1 - fixed time interval - one picture every 2 seconds.
2 - ramdom interval between 3 and 5 seconds.
On the fixed time interval I got all 100 pictures
On the random time interval - even with interval greater than 2 seconds I always have failures - doesn't matter if I'm using 1 or 2 cameras,
I tried to increase, decrease the time intervals and always when is random - like happen when I'm flying, I have this failure problem.
