No controller found (linux)

[Joerg]

EDIT: after reading this thread viewtopic.php?f=22&t=11 it would appear that everything should work (I have the e-sky 0905A controller). The reason for it not working is beyond me...

Note that I have that controller running under Mac OS X - which handles devices and such quite different (since it's a BSD-based OS, rather than a Linux one...)

In your first posting, you mentioned a java.lang.UnsatisfiedLinkError - do you still get that one when launching the sim?

Oh, it was on osx, I see. Yes, java still outputs the same error (exactly the same).

Hi,

there are two playces where errors could appear: The log file files/log.txt (which you showed and where nothing strange is in, besides "no controller found") and the console. Are there any errors in the console coming up?

Thank you.

Michael

[lerneaen_hydra]

Yes, the console reports;

Ok, there is still a problem with the native code. This code should be in libs/jinput/linux-i586/jinput-linux.so

Please look if the file is there and you have enough rights to read it. There is an update available:

http://jinput.dev.java.net/servlets/ProjectDocumentList;

Perhaps you want to try this one?

The current file I have was -rw-r--r--, so I could read it. After adding the new file (https://jinput.dev.java.net/servlets/Pr ... entList%3b. latest jinput binaries) into the heli-x directory and performing a 'chmod u+rw /dev/input/j*' and e* it starts correctly and correctly finds the controller. The simulation works perfectly now. Thank you all very much for your help!

Now I just need to practice flying

Now I just need to practice flying

This is the difficult part ...

Hello all,

I have just found this nice sim and I'm trying to run it on Linux (my only operating system).

I really need it because I'm transitionning from an easy to fly Lama v3 to a CP heli (Walkera 60B)

First I encountered the problem described in the previous messages and the updated lib found here http://www.newdawnsoftware.com/resource ... latest.zip solved this problem.

Now I can launch Heli-x, load an airport and a model. It looks very nice

But my controller is not detected.

It is an E Sky 0404 Radio + USB SoftDog EK2-0900A

log.txt says :

Code: Select all

Trying to open xml File /home/rossi/Helico/HELI-X/files/controller/PPM.xml
Could not find stick 
Could not find stick 
Could not find stick 
Could not find stick 

My radio + cable are correctly recognised when I launch the windows sim HeliSimRC.exe with wine.
Everything works as expected.


Here is what dmesg says when I connect the usb adapter :

Code: Select all

usb 7-1: new low speed USB device using uhci_hcd and address 94
usb 7-1: configuration #1 chosen from 1 choice
input: ? PPM as /class/input/input15

The USB adapter is visible in /proc/bus/usb/devices :

E:  Ad=81(I) Atr=03(Int.) MxPS=   8 Ivl=20ms

I also lauched Heli-X as root to be sure there is no access restrictions on /dev


Is there a solution to this problem ?

[Michael]

Hello,

I am a little bit confused: You tell us a part of the log file: /home/rossi/Helico/HELI-X/files/controller/PPM.xml

But this file is only opened when a controller is detected by HELI-X. On the other side it is mentioned that the controller is not recognized. This is contradicting. Please try the following: Delete all xml-files in /home/rossi/Helico/HELI-X/files/controller.
Give (as root) all userrs all rights on /dev... as decribed above. Start HELI-X as normal user.

Hope that helps.

Michael

Thanks for your answer

I deleted this file and launched again Heli-X as root (or user, it makes no difference)

radio sticks moves are not detected in the configuration dialog. Here is the log file :

Really strange !
