VKB Device Config - Helicopter style Trim

Postby hon0 » Wed Mar 06, 2019 23:32

Hello Alex.

I would like to ask you a new trimming option. Similar to what we find in Helicopter. Physically, it would require two buttons. One for trim and the other for reset.
The reset button usage is straight forward, we press it and the trim reset as it does today. (With soft reset it is even better ♥ although the feature is broken at the moment).

The trim button however is more complicated, here is how I would personally like it.
Let's imagine we want to trim a helicopter cyclic. Mapped to our X and Y stick axes.
- On Trim button press and hold, axes are frozen and their value are applied as trim. X value applied on X and Y value on Y.
- Now we physically bring the stick to neutral position. We have all our time to do so as long as the Trim button is held. (Unlike in DCS where we have limited time).
- On Trim button release, axes are unfrozen.

On next Trim button usage, it should do the difference from the preview trimmed position, not the stick center.

I use this method for many years on my Warthog thanks to Target script editor, however I haven't found a way to do it with my Gunfighter yet.

Thanks,

Antoine.

PS : An other improvement to that feature would be a soft Trim button release. To prevent jump of the axis when we release the button while the stick isn't perfectly centered.

Hi , Hon!

Try use function FA0 , and enable trimmer for these axes (XY in phisical axes) ( also Global flag FA )
I think this is what you need.

PS/
- Sorry, I missed you message http://forum.vkb-sim.pro/viewtopic.php?p=34046#p34068 - I will check it now.
- checked - bug is confirmed, thank you. I will try to fix it in the near future.
- Lets try and check v1_96_A




PPS.
Better write to me here https://forum.il2sturmovik.ru/topic/970-%D0%BF%D1%80%D0%BE%D0%B3%D1%80%D0%B0%D0%BC%D0%BC%D0%B8%D1%80%D0%BE%D0%B2%D0%B0%D0%BD%D0%B8%D0%B5-%D0%B4%D0%B6%D0%BE%D0%B9%D1%81%D1%82%D0%B8%D0%BA%D0%BE%D0%B2-%D0%BE%D1%82-vkb/?page=48

I just tested 1.96A and soft reset work, however it is very fast in Rate Trim.mode, even with the slowest option, which is the higher Trim.time value, 1000. I don't know what value would work for me, so.. Could you let us define our own value?

Now I'm trying FA0 and I can't get it to work, am I missing something?

Next time instead of creating a topic here I'll post on the IL2 forum, thanks for letting me know.

In your opinion - how many times need to increase all Trim.time values ?

First value I would try would be 5000 (In rate mode), and adjust up or down from there. Now, this is just my opinion, I want my reset to be really smooth so that I can make them transparent. By the way, it is a good opportunity for me to ask you if you could add some acceleration to the reset acceleration hehe. Some jerk. To smooth both the start and the end of the reset processus. Yes, I'm quite perfectionist. :oops:

Edit : I missed you asked for my profile to check the FA0 problem, here it is (my Software/Firmware version are in my signature):

Thanks - I check it. In you config FA0 really not work, configuration is correct.

This is strange - in this configuration work :)

I will find out the reasons.

---------------------

As for the variable speeds - I can not yet say .

Trimmer Rates will change.

Oh indeed I got it working on Input #1, strange. Eh, you made it work exactly how I wanted it! Awesome! It is.. As if it make sense :wink:

Now to improve that feature and make it even more transparent I would love a jerk setting. To soften the soft reset.
And also, a soft "FA0 button release". To prevent jump of the axis when we release the button while the stick isn't perfectly centered.

Thanks again for your work.

Complex nonlinear curve probably will be difficult to implement.

What about this?

That would be an improvement yep. Could more "point" be added? I guess 2 or 3 point at each end would be enough.

Hmmm

It's a thought - use some curve for to change not speed, but amplitude.Visually, it will be like a change in speed.
This is probably possible
This will allow the use of a sufficient number of points.

Can you calculate values of this points ? (value interval 0-255)
points must have a uniform distribution in time

PS I think we may use 8 points

Now v1_96_A(2) is ready.

1. Fixed FA0 on any button
2. Trimmer Rates multiplied by 10 times - value 50 = 500 ms, 500 = 5000ms for range 100%

Please check it.

OK
I'll think about the trimmer curve for now.

I'm testing v1_96_A(2)
FA0 button fixed.
And I also love the new rate. Flying a Helicopter I will use ~5000ms in rate mode.

Thanks a lot!

Side note : Could we have a option in the "Settings" panel to choose the starting value of "poll" in Profile - Buttons. Each time I go there I want to tick it to check my config.
