Re: CAN

A few comments on CAN:

-The serial bridge is speed limited. The 2CAN can talk much faster on the CAN bus, so theoretically you can update more motor controllers faster without lag.

-I spent a good deal of time over the summer working on an automotive/military CAN bus (I can't talk about), and termination and bus design is VERY IMPORTANT for CAN. If you don't terminate the bus, or have weird splits and branches (e.g. you try to star wire it instead of daisy-chain, or your taps are too long relative to the bus length), it will hate you.

-I have yet to find an FRC robot that *NEEDED* a Jaguar instead of a Victor, the need for CAN is (to me) yet to be seen.
