Using CAN and PWM at the same time?

Hi there!

We're wanting to do some bench tests and want to record the motor amperage, voltage, RPMs, velocity, and acceleration. We're going to be using the black jaguars (the only way to measure the amperage and voltage?)

I'm wondering if it's possible to use PWM to drive the motors and CAN to read from the controllers.

I didn't want to drive from the CAN bus just so we can keep from hogging the bus. Maybe I'm mistaken?

The only reason we're using Jags is to read the amperage and the voltage. If there's another way to get these readings without using the Jags, let me know :-)

Thanks!
