Re: Odd PWM problem (Can't get full green)
Allen,
In both controllers, the calibrate feature conforms the travel of the joysticks to the controller. The only reason that you would not receive a green following a calibrate is that the joystick is not returning to the same value at which it was calibrated. Are you using a calibrate routine in software or the full travel of the joystick when calibrating?
Now, there is always the possibility that the green LED driver is defective. Do you ever see the LED come on green? It should flash Green/RED when the calibrate mode is active. It should flash Green/Yellow when the calibrate has been successful. Remember that the Jags have a 15kHz output switching frequency and many meters will not measure accurately at that frequency. In addition, Jags generate a reverse pulse to charge the bootstrap cap when at full throttle, this will also generate some error.
