Drive wheel motors using OItoPWM() --- how to debug?

Not necessarily. Most joysticks don't quite reach the entire range of possible values. You can compensate for this in teleoperated mode by calibrating the Victor speed controller to match what your joystick provides.

(Note that the maximum PWM value in the IFI control system is 254, not 255.)

Is there a way to read the output to the PWM while running the OI_to_PWM() function using EasyCPro? I mean without any hardware equipment?

If you already have a laptop computer with a serial connection, you can use a dashboard reader program to see exactly what pwm outputs are being commanded, and exactly what joystick values are being read.
