Unexplained intermittent CAN / 2CAN Jaguar problems at GSR

[Andy A.]

As another data point-

95 also had CAN bus issues at GSR, as did several other teams. We used all black jags and the serial port. It was enough of an issue that FIRST personal polled CAN teams and advised them that they couldn't say what was going on, but that it seemed like CAN wasn't always working. We elected to switch to PWM control (which also brought a half dead sidecar to our attention).

The last I had heard was that a common factor in all this was that the team was using Java as their programming language. Beyond that, there didn't seem to be any commonality. I heard some accusations of it only occurring on one driver station, or side of the field, but I can't confirm if that was true or not.
