CmuCam problem

try drawing your power from the digital out instead of the PWM out that fixed the problem for us with the camera not tracking

That's odd. The PWM out should supply 7.2V needed from the backup battery (which must be hooked up), where as the digital port should be only 5V, and not sufficient to overcome the drop in the voltage regulator on the camera. Also, the servos, if plugged into the camera, should require the 7.2V to operate as well. If they are plugged into the RC, then it should still be needed.

But I guess if it works...

My bad, Windows 2000 Service Pack 1, I had to go buy Win XP yesterday.

Thanks for the help. we got the cam working. there was a problem with the backup battery. it would power the camera but the servos wouldnt move. after changing the battery it started to look for the target. As in other post the camera moved away from the target. switching the jumper fixed that. it works perfect. if you are haveing any problems try to change the battery. also change the jumper. so it doesnt run away from the target.

That's good news.
I've been away from CD for a few days visiting rookie teams, so I'm sorry about not responding with more ideas Zoom.

What if our problem consists of putting a (I think) transformer in incorrectly and blocking it off from the air, accidentally melting it?

This did actually happen, but the camera still works (not quite as well) and we're getting some new parts.

Hey-

Out team is having a horrible time with the camera- much like what everyone else is having in this thread. The only difference is sometimes the camera will search and sometimes it won't. We had the camera working at one point, but now it doesn't. We started from square one, but it still won't work. We're using the camera_s code, and we have calibrated the camera just as the instructions say. We noticed that the red light goes on when the camera sees the target in LabVIEW, but when we try to search with Kevin's code, it seems to be seeing the target all over.

If anyone can offer any help at all it would be much appreciated!

pwm 1 and 2 are right on the camera board...on the top or bottom.....depending on the mounting of your camera

Did you try changing the focus of your camera, ours works fine. But If its focussed wrong it wont track it at all.
