Detailed Description

Joystick settings.

This structure contains joystick parameters. If joystick position falls outside DeadZone limits, a movement begins. The speed is defined by the joystick's position in the range from the DeadZone limit to the maximum deviation. Joystick positions inside DeadZone limits correspond to zero speed (a "soft stop" command is issued continuously), and positions beyond Low and High limits correspond to MaxSpeed[i] or -MaxSpeed[i] (see command SCTL), where i = 0 by default and can be changed with the left/right buttons (see command SCTL). If the next speed in the list is zero (both integer and microstep parts), the button press is ignored. The first speed in the list shouldn't be zero. DeadZone is defined in 0.1% units.

The relationship between the deviation and the rate is exponential, which allows for high mobility and accuracy without speed mode switching.

Maximal deviation is +-25.5% that is more than a half of the total joystick range.

unsigned int ExpFactor

Exponential nonlinearity factor.

unsigned int JoyCenter

Joystick center position.

Range: 0..10000.

unsigned int JoyFlags

Joystick flags.

unsigned int JoyHighEnd

Joystick upper end position.

Range: 0..10000.

unsigned int JoyLowEnd

Joystick lower end position.

Range: 0..10000.
