Clarification of Team Update #5

Part of Team Update #5 states that we are only allowed to send 1024 byte packets from the robot to the driver station.

Even before this update I figured out how to use the librarys to send custom packets from the cRIO to the computer. Using this I built a pretty-reliable (though not perfect) way to print formated debug messages across the ethernet complete with its own checksum. =P

When I first got this working I noticied that the first 8 bytes of the packet are untouchable, and that no matter what the packet is always 1024 bytes long.

As far as I understand the packets I send from the robot don't go to the driver station, they go straight to the computer.

I heard that you can have a laptop with your driver station. Does that mean I can plug a computer into the driver station during a match and get custom packets from the robot?

I have plans in which I could get data from the robot and display it on the computer which would be useful to the drivers. Is this legal?


P.S. If anyone is intrested in my system or what I've discovered while messing with the cRIO's communications just ask.
