v7 dead band problem

[olegan]

HELI-X 7, Linux 64bit, RealFlight controller.
All sticks have dead band, even the throttle. Dead band settings in Flight Mode are at 0.
Here is a video: https://youtu.be/5NLq-2wvQG0

Version 6 works just fine, so the controller itself is ok.

Yuu can try the different input systems: global options->input system

Thank you, Michael

Code: Select all

jinput-b1.jar

did the trick

Sorry to resurrect this old thread.

Heli-X 7, Ubuntu 18.04 64b, Cypress USB dsmX HID, same problem, but none of the input systems improves the situation.

I've triead all input libraries (-b1 does not see any controller in my case). The others all work the same with lots of dead band. The controller works fine in another simulation on windows.

Edit: The controller also works fine with Heli-X in Windows (jinput-b8, default did not recognize any controller).

Is there a chance to calibrate the controller in Linux?

[eraserix]

Yep, turns out you can. Good writeup: https://wiki.archlinux.org/index.php/Gamepad

What I ended up doing and what seems to solve my problem on Ubuntu 18.04:

1. Code: Select all

   apt install joystick jstest-gtk

2. Run jstest-gtk and calibrate your stick. This turned out to set the dead zones to reasonable values. Take note about the device path displayed in the tool, e.g. something like /dev/input/js0
3. Store the calibration values of the device. This avoids having to recalibrate the device after every boot. Use the device path from step (2)

   Code: Select all

   sudo jscal-store /dev/input/js0
