SmartDashboard Poll

[Jefferson]

To be clear, it wasn't us who thought that your settings weren't right. Greg came to our pits to check our camera settings as well. We were in the middle of trying to figure out how WE could have caused the weirdness we saw that match. The robot was very unresponsive, leading to over corrections in steering, and then it looked like the motor outputs got stuck for a couple seconds.
Our DS logging showed significant communications issues, but we don't know who was at fault... could be FMS as far as I know. We only had issues in that one match.

To add a little insight: we have a few dozen variables on the dashboard, but they only update when a specific joystick button is pressed. This allows us to have all the trouble-shooting tools we could need in the pit, while not overloading the network during a match. All we have running during a match is the camera feed.

Sorry I edited my post to make it clear... it was just a theory from the FMS team. Greg came over to our pit as well and I showed him the setup. We did have a lot of real-time parameters updating for debugging purposes on the SmartDashboard (about 30 or so)... hopefully that's wasn't it. To be safe, I'm going to change the setup so only the camera feed is running continuously during the match.

What's odd is how 2 teams lost/regained communication at the same time... and the idea that somehow one team could mess up another team. I thought that was the whole reason for limiting everyone's bandwidth.

I refer both to the Java application that runs on the Control Computer and to the class of the same name that communicates with it via NetworkTables. That they use the same name instantly draws the connection between them in ones mind, and I can't believe that wasn't intentional.

We disconnected the camera (configured at a 1.7 Mbps consuming 320x240x30x30%compression) and quit running the Java application as I was advised by the FIRST personnel. This resolved our issues for the remaining matches.

I specifically asked the FIRST representative if I needed to remove the SmartDashboard class calls in my code and the answer was that to stop running the Java application was sufficient. Again, this representative was explicit in making sure I was talking about Brad Miller's Dashboard vs. any other Dashboard application.

Okay, yeah, maybe I should have posted this in the common Programming forum. I sorta forgot that this feature was common with our Java friends.
