Version 3.0 of my multi-throttle software for IL-2 is done. It adds a lot of functionality to the G940. Now using device link to get 100% accurate throttles like normal in IL-2, and also support for the toe brakes for individual wheel braking.

I made a program to let you control your G940 lights manually (on a basic level at least).

Enjoy!

An update on the G940 as flight sim equipment:

I finally went about trying to tune my trims to let me really 'trim' properly and accurately, since I always had a bit of an issue except with the elevator. I lowered the range of them in the profiler a lot to make them far easier and casual to use.

And I found that I had real issues trimming it in so that I could fly completely hands off stick. And the reason: the reversal bug. Every time you start moving a trim in the 'other' direciton it makes a jump, so when trying to trim it just right - ah, a bit too much, go back, wtf, too much, and so it keeps going.

DxTweak doesn't work with the G940 stick (crashes if you try to read it), but I took the time to use the IL-2 Joy utility to see if the stick itself is affected by the reversal bug, and it is. Every single axis is affected. This is outmost annoying. I'm sure it affects my aiming in some instances to a minor degree (but there should be NO degree), and it sure affects trying to trim properly, and the throttle accuracy as we already know.

That Logitech software update with new firmware to fix this nonsense bug really must come out - soon. Feels handicapped to have this issue plauging every axis, even if the effect is small.

That sucks, can't believe they're taking so long to fix a rather show-stopping bug. Does DIView work?
Getting pretty sick of peripheral manufacturers using weird proprietary calibration interfaces...they should've made the separate components of the G940 work independently, even if it meant they used up 3 USB ports...if you can afford to buy the G940 I'm pretty sure you can buy a powered hub. And the only other reason they provided for not doing so was that some older sims only recognise one controller...why didn't they just bundle their own variety of PPJoy with it?

DI View does work, thanks! Never heard of it before. Cannot calibrate or change anything with it, but can at least check out the axis behaviours.

I realized I could implement a little correction filter in my multi-throttle software for the G940 at least (But only for what is controlled through device link - don't think it would work well to pipe everything through there). I have already fixed the throttle reversal bug there, and setting up the wheels now. At last, no more annoying throttle jumping too far or the trims being unagreeable in finding that perfect sweet spot.

EDIT: DIView cannot see the last axis of the G940 stick - the "X" axis of the 'mini joystick' (top hat). Neither can AutoHotKey. I think some of these windows APIs just can't recognize more axises. And perhaps this is a reason Logitech split up their devices - too many axises for one device.

Also I suspect this is the reason that DXTweak2 crashes - one too many axises.

The Ministick axis that does read though is very accurate, interesting. Although I can't think of a use for it (beyond using it as a digital trim hat in the sense that the F-16 Fighting Falcon is trimmed - aileron and elevator - wouldn't feel right (or would it?) for an old WW2 plane).

I think you're right, I think the maximum is 8 axes per device in DirectInput. I'd probably use the ministick just as mouse panning because I don't really use my TrackIR3, not enough room on my desk to stick it in a useful position, it's too easy to go outside the tracking range.

I thought I would update this topic as it is in the IL-2 forum, and it's about the G940: I have now managed to supply support for the G940 for IL-2

Reversal bug removal of most axes
Toe brake support
Dual throttle support
Throttle LED colour support (yep, if the gear is down it will light up green, tail wheel unlocked and it is red, WEP is on and it flashes red, arrestor hook down and.. so on).

Nice support MikkOwl.

I hear Logitech is still working on a driver update. If they fix the sloppy centering I'll give the G940 another go, and try your programming.

Forwarding some news from the Logitech support forums, in my own words:

• Logitech Profiler (the main drivers/software) was getting a major rewrite (6.0 - Don't remember) that has been worked on for a long time, since September we assume, 7 months. So long that the bugs of the G940 was really infuriating users, who were kept in the dark about any updates/bug fixes. Enough angry customers and probably to patch the damaged reputation of the G940 has made them divert resources for a minor (but major in importance) update, version 5.09.
• 5.09 is not far from release. Has seen limited distribution to software developers for last minute feedback.
• Focus of release is bug fixes, but not entirely.
• Profiler bug fixes are mentioned.
• Unspecified functionality bugs to be fixed (probably the reversal bug which is pretty major, and was confirmed as being worked on to fix in December 2009).
• Changes/work-arounds of force feedback implementation in third party games (that would be all games that has force feedback support I suppose?). Centering spring force is mentioned specifically. I believe it most likely to be the 'slop' issue in sims such as IL-2.
• One type of BSOD eliminated.
• New capabilities of the device will be unlocked.
• More specifics coming within a week.

Great news Mikk!

thanks for the news.

cheers
