INT8U ExpFactor Exponential nonlinearity factor.

INT8U DeadZone Joystick dead zone.

INT8U JoyFlags Joystick control flags.

0x01 - JOY_REVERSE (Joystick action is reversed. Joystick deviation to the upper values correspond to negative

speeds and vice versa.)

INT32U CMD Command (answer)

Description:

Set settings of joystick. If joystick position is outside DeadZone limits from the central position a movement with speed, defined by the

joystick DeadZone edge to 100% deviation, begins. Joystick positions inside DeadZone limits correspond to zero speed (soft stop of

motion) and positions beyond Low and High limits correspond MaxSpeed [i] or -MaxSpeed [i] (see command SCTL), where i = 0 by

default and can be changed with left/right buttons (see command SCTL). If next speed in list is zero (both integer and microstep

parts), the button press is ignored. First speed in list shouldn't be zero. The DeadZone ranges are illustrated on the following picture.

The relationship between the deviation and the rate is exponential, allowing no switching speed combine high mobility and accuracy.

The following picture illustrates this:

The nonlinearity parameter is adjustable. Setting it to zero makes deviation/speed relation linear.
