This works under Linux only, which is certainly suboptimal. But there's no
reason why support for other OSes couldn't be added later, and there's no
reason to not support Linux now, either. The code can set the throttle's
backlight brightness and the five programmable LEDs. As a demonstration,
the latter is currently used for a gear-down warning. Support for setting
the stick's hardware deadzone is planned. (It's on by default.)
The mechanism writes directly to Linux' hidraw devices, which requires
some simple configuration. This is described in the README. It doesn't
depend on any external utility.
These files take complexity out of the main joystick file, while
not adding much code. They also update the description (<desc>)
used by the Help->Joystick information dialog. All <nasal> code
is executed in the joystick's namespace, so variables and funtions
of the main file (popup()) can be accessed.
