Re: 2015 Beta Testing - PWM voltage levels

We did a brain transplant of the 2015 control system into our Aerial Assist practice robot. The drivetrain motors are paired up with one PWM output driving two Talons for each side, and the four flinger motors are similarly controlled in pairs. It's been working great so far.

We have been working around a Driver Station issue introduced in the previous Beta release and haven't yet had a chance to do the brownout and stress testing that's next on our agenda. New Beta files were released this week, so we'll be updating the RoboRIO image on Monday and watching how the system responds to low voltage and high loads. Once we've gathered the information we want, I suppose we could wire up a slew of motor controllers and see how many we can reliably control with a single PWM output.
