Re: Does the RoboRio have mounting holes?

Re: 2017 Montreal Event
Likewise! There are a couple of teams in Quebec that would consider going to Hawaii if the regional fell during March break. Would be a good recruiting tool too :)

Re: PWM to CAN LabView arcade drive
The drop-down under the initialize motor drive block needs to be set to the type of motor controller you're using.
