Re: Flashing from EasyC v4 to RobotC 2.25 for Cortex & PIC
All of the wireless/VEXnet functionality is enabled by default in ROBOTC. Have you updated the firmware on the VEXnet Joystick and Cortex? Have you paired the VEXnet Joystick and Cortex using the USB A-to-A cable since updating the firmware?
We have a set of setup instructions here: http://www.education.rec.ri.cmu.edu/fire/competitions/best/
where you can verify that you have the correct settings for using ROBOTC and VEXnet.
