Just to be clear: CAN
is a
serial protocol. 2CAN
also uses serial protocols (Ethernet on the cRIO side and CAN on the other).
What you meant is that Ethernet (2CAN) is faster than the RS232 connection from the cRIO to the Jag. No argument there.
But I'd bet a hundred bucks that reading the FPGA is faster than querying the Jag for speed.

One thing we did try was having the second motor in brake mode ... but it got too hot for our liking.

That's one reason why the paper says don't use brake mode.
