Re: paper: DIY 'encoder stage' for VersaPlanetary

AWESOME! This is an amazing modification! A VP encoder stage without adding extra space is amazing! It seems a bit tricky to do right now, but not to the point that it can't be done. I'll have to try this on our mill.

EDIT: The Talon SRX has 80,000,000 / CPR maximum RPM. So 80,000,000/ 30 = 2,666,666 max RPM. I think we'll be fine as far as counting ticks goes.
Does the sensor sense direction? It appears to have a quadrature detection scheme, but I was not sure.
EDIT2: For the CRIO, Ether mentioned that the max polling speed for a quadrature encoder is 2,129 RPM for a 360 CPR encoder in the worst-case scenario. For a 30CPR encoder like we have here, that's 25,548 RPM max. That should be compatible with your typical FRC motor.
