Re: Motor speed sensing with the Jaguar motor controller?
Digging into the LabVIEW code, it appears that the Set Speed and Get Speed VIs just end up setting and retrieving the PWM output value (0..255) by way of a speed value (-1..1). By default, the VIs assume the motor's speed is linear from 0 to 255. If it isn't linear, you can specify your own VI to do the transformation.

So, there is no speed feedback from the Jaguar at this time. It is possible that speed will be available over the CAN bus in the future, but I don't know.
