[Plib-users] Auto-calibration working in windows, not in Linux

[Julien M. <dp...@ya...>]

Hello,

I'm playing the game Torcs, and i've two racing wheels (1 Logitech Formula
Force GP, and one cheap APM wheel). I've exactly the same problem with
both.

In windows they're working correctly (probably using the calibration
values from the control panel?), in Linux often the movement isn't
detected at all.

I'm using the CVS version of Torcs, and the 1.8.3 of PLIB. I checked with
js_demo, it always returns 0 for the axis (buttons are OK). so i modified
the js_demo source to replace the read()'s by rawRead's, i get values like
30 - 400 - 900. Something strange is that those values are different from
those i get with jscalibrator (it uses the libjsw library IIRC but i
thought the values displayed were also those given verbatim by the OS?)

I then modified it putting back the read's, and at the beginning i've put
setMin/MaxRange and setCenter and hardcoded the values for my wheel. This
way i got correct values -1,0,1 with read.

In windows there is a centralized standard location for the calibration
values of the control panel (registry?), but i think there is no such
thing in Linux.

Is there a plan to use something similar in Linux? (jscalibrator writes a
~/.joystick, or maybe we can use a system-wide file like /etc/joystick?)

Regards,
