NAME

       joyhandle - sets nonlinear joypad movements, deadbands and scales

SYNOPSIS

       loadrt joyhandle [count=N|names=name1[,name2...]]

DESCRIPTION

       The component joyhandle uses the following formula for a non linear joypad movements:

       y = (scale * (a*x^power + b*x)) + offset

       The  parameters  a  and  b  are  adjusted  in  such  a  way,  that  the function starts at
       (deadband,offset) and ends at (1,scale+offset).

       Negative values will be treated point symmetrically to origin.  Values  -deadband  <  x  <
       +deadband will be set to zero.

       Values x > 1 and x < -1 will be skipped to ±(scale+offset). Invert transforms the function
       to a progressive movement.

       With power one can adjust the nonlinearity (default = 2). Default for deadband is 0.

       Valid values are: power >= 1.0 (reasonable values are 1.x .. 4‐5, take higher power‐values
       for  higher  deadbands  (>0.5), if you want to start with a nearly horizontal slope), 0 <=
       deadband < 0.99 (reasonable 0.1).

       An additional offset component can be set in special cases (default = 0).

       All values can be adjusted for each instance separately.
