I am implementing the Joystick axis using a DPAD connected to the GPIO .  I have only implemented the POV_X and POV_Y  for time being.

I am creating the axis like this  inside my JoyInput implementation

this.povX = new DefaultJoystickAxis( getInputManager(),
                    this, getAxisCount(), JoystickAxis.POV_X,
                     "POV_x",
                    false, true, 0 );

I have flycam enabled in Jmonkey App.

When I press the buttons, the camera moves in the correct direction with speed.

When I release the button press, the camera stops moving with speed, but it keeps moving in the same direction at a very minimal speed.  I am confused as to what is causing the minor camera motion inspite of no events being generated. What does the isAnalog variable in the DefaultJoystickConstructor do - does it have any relation to this behavior? I have set it to false.

 When I press the button a JoyAxis event is created like this in the JoyInput implementation

                if (name.equalsIgnoreCase(RemoteButtons.DPadL.name())||(name.equalsIgnoreCase(RemoteButtons.DPadD.name())))
                {
                value = -1f;
                }
                else
                {
                value = 1f;
                }
                if (name.equalsIgnoreCase(RemoteButtons.DPadL.name())||(name.equalsIgnoreCase(RemoteButtons.DPadR.name())))
                {
                laxis = vjt.getAxis("POV_x") ;
                }
                else
                {
                laxis = vjt.getAxis("POV_y") ;
                }
                axevt = new JoyAxisEvent(laxis,value);
                listener.onJoyAxisEvent(axevt);
