 I was just thinking of a more general way of solving the 
 calibration issues than putting it into the configuration files.

I have used systems (PS, PS2, the driver for my Saitek joystick under
Windows) which appear to monitor the highest and lowest values that have
been seen from a given axis, and assume that these are the extremes of
the axis. Obviously when you first start it up, everything is very
jittery, but you just need to move all the axes to each extreme and the
calibration is set. In fact the PS/PS2 instructions say to move both
analogue sticks in circles before using them, I guess this is to effect
the calibration.

Would it be possible to use this approach for FG?

One could argue that moving all controls is an essential part of the 
pre-flight checks, so why not using that for calibration? Just makes the 
sim even more realistic ;)

 some time ago a new version of the joystick configuration file for
 Logitech Wingman FF 3D was committed, containing a change to the
 throttle-handling.

 Shortly after that I couldn't get the engines down to idle. As I
 noticed, jsdemo reports that the throttle axis returns +0.3 when on
 idle. I'm using Linux on a 2.6.8 kernel.


That configuration file applies an offset of -0.3 prior to the scale.  That 
shouldn't be allowed, and I guess someone's personal configuration snuck in 
by accident?

The major change to that file was that appropriate Nasal-scripts are 
used on throttle and other axes and that's a Good Thing (tm). However, 
that effectively broke the calibration that was in there, as 
throttleAxis() and friends don't currently support these offsets.


I was just thinking of a more general way of solving the calibration 
issues than putting it into the configuration files.

I don't think so in this case.  That offset apparently worked for most people 
with this stick - I know my throttle's been broken since using the new 
nasal based config, in that I can never get the throttle input less than 
0.24.  

If an offset fixes a problem for everyone with this stick, I can't see any 
valid argument against it.  If the offset required is completely 
unpredictable of course, it's not an acceptable solution.

I would be interested to know if anyone has a Wingman Force 3d which gives the 
correct full range of throttle values with the new config...

Cheers,

AJ

Mine does, but then since I sent in the patch I probably don't count...

I wonder if it is OS or USB specific? I've got a USB version and run under
WinXP.
