I have been using a PixHawk to trigger my Canon PowerShot SX260 (equipped with CHDK) in a UAV and it seems to be sending voltage pulses too quickly. The camera will take pictures while running the predetermined flight path, then continue to take pictures even when it was put into manual mode (pictures should stop) and we will have images all the way up to when it lands and sometimes it will even continue to take pictures of the ground while it's just sitting there.
My initial theory is due to a "build-up" of these pulses since the camera can't register them fast enough, but I'm not sure if that's possible. I consistently notice the camera won't take nearly as many pictures as it was supposed to, as well. Is there an ideal speed to send these voltages? I seem to produce relatively good results when the camera takes a picture every 2.7s, but I have only been able to get it to do that once and am still having some issues.
That being said, is there any way to reduce the amount of time it takes the camera to take a picture utilizing CHDK? So I wouldn't have to slow the voltage pulses and can just increase the picture speed of the camera?
Any insight/comments are welcome!
