Problem with easy C CameraTracking function

[mjveld1018]

Yes, the camera is initilized (the terminal shows "->" and "<-"). We are still getting 0 for all values though. We're powering it off of the RC with a fully charged backup battery.

Were there ACKs going by with a number of different commands being sent to the robot? Sometimes if the robot controller can't connect to the camera, you see a bunch of "->" and "<-" without and commands being sent. This is because the robot controller is waiting for the camera to reply and timing out.

If it is working it will finish the entire initialization sequence in less than a second.

We got something that looked like this (I don't remember the directions of the ACKs):

<-
<-
->
<-
<-
<-
(then it started the printf statements we told it to make, returning zeroes for all functions)

Thanks for the advise so far!

If you are only seeing the arrows, then it means that the robot is not getting any data from the robot controller. When it works you should see a series of commands along with the arrows.

So, I would try one of the easyC camera demo programs that work for sure just to make sure that you are not having a software problem. If that doesn't work, then you might have some issue with the camera itself or the connections to it.
