No Robot Code

By the way, the problem has ceased to go away when we reimage. It does not happen though with the default FIRST code, so it seems to be a code problem. However, it also doesn't happen with archived code from a week ago, even though it clearly should if it's a code problem.

Correction: yesterday the code from a week ago worked. Today it doesn't. Default still works though.

Reviewing the meaning of the LEDs may help a bit. The robot LED means that the robot IP ping succeeds. The communications LED means that the communications task on the cRIO is responding to the control packets being sent from the DS. Finally, the Robot Code light really means that the robot code is calling into the communications task often enough.

If the cRIO is vastly overtaxed by the code you are writing, it might behave the way you describe, where the WPI framework is not being updating the battery value and other fields as it is supposed to.

I don't remember what language you are using, but if you can determine the CPU usage via spy or a similar tool, it may help you figure out what portion of code is responsible.
