Activating the potentiometer option allows the inclusion of potentiometer.c library into the project. The pin is regularly sensed in the medium frequency task (MC_APP_PostMediumFrequencyHook_M1) and any change applied as a speed ramp.
The UART is used by the MotorPilot to communicate with the microcontroller. You can launch the GUI from the corresponding icon on top of the workbench window.
I suggest to introduce the MC_StartMotor1() call once you are sure the motor is properly controlled by the MotorPilot. If the motor spins for only 1-2 seconds, it is likely a problem with speed PID gains leading to overcurrent or wrong connection or improper connection position of the sensors.
