Re: Unexplained intermittent CAN / 2CAN Jaguar problems at GSR

It sounds like the experts are convergent on the problem and we remain hopeful for a robust CAN solution. For anybody following this CAN problem thread, there was an interesting statement in the March 8 (yesterday) Team Update #17:

Quote:
If a team is using a CAN network on the robot, they should check the messages in the “Diagnostic” tab of the Driver Station before a match starts to ensure that there aren’t any scrolling CAN timeouts. If there are such messages, give the MC a “thumbs down” to show you’re not ready and click on “Reboot Robot” to restart the cRIO and clear the errors. Teams will only see such timeout errors if it's properly handled in code, and they should take care to ensure that these exceptions are handled such that they can be seen on the field.
I’m going to try to convince our team that we should maintain our CAN implementation (not go back to PWM cables) but carefully monitor for this possible problem.

Thanks again,

john
