I apologize for not including the URL in my first reply. In your case you would go to
roborio-3633-FRC.local and as for assigning the Talons, you would first have to know what port to enter for it, an example for it would be:
Code:
motorExample1 = new CANTalon(1);
//Later defined in the private variables section (If you are doing a non-command based)
CANTalon* motorExample1;
Then using the port '1', you would simply click the motor in the GUI and assign it to the desired port (1 in our case) then you're all set!
Let me know if you have anymore questions!
