Joystick

Hello
I'm trying to install a Logitec Dual Action joystick whith EMC2 2.5.1 on ubuntu Hardy Heron using this link wiki.linuxcnc.org/cgi-bin/wiki.pl?Simple_Remote_Pendant..
Step 4, EMC crashes when starting.
The joystick has been calibrated whith no problem (jscalibrator).
i've tried other solutions (discribed in wiki.linuxcnc.org/cgi-bin/wiki.pl?LinuxCNCKnowledgeBase) whith never endind problems of missing packages, wrong version of installed packages and install errors.
Is there a solution?

Hello John
Here are the attachments. I also add the error message when EMC crashes at start. If a copy of my machine.ini and hal files or custom_postgui.hal could be helpfull, I can send them.

ps : EMC crashes when hal is modified as discribed in the help link.

The name of the button changed at version 2.5 or 2.5.1

hello ArcEye

I've tried to rename trigger in joystick, but emc crashes. In attachement, hal file, EMC error message and halcmd show pin. I've very poor knowledges whith Linux and I do my best to understand !
I can't attache doc, so I do a copy

Hi

insmod: error inserting '/usr/realtime-2.6.24-16-rtai/modules/rtai_hal.ko': -1 File exists

This normally occurs where a startup has failed but left modules not properly unloaded, the next time you try to start you get this error.

Your button is now recognised,

5 bit OUT FALSE input.0.btn-joystick
5 bit OUT TRUE input.0.btn-joystick-not

so this is a different error.

Reboot to clear everything and try again

regards

That's quite ok after reboot but.....
The joystick does not act in anyway and no error message!

notice ; the tutorial say "postgui.hal" but I only find a "custom_postgui.hal" in the directory.
