when i run "halrun" and type in:
loadusr -W hal_input Code Mercenaries KeyWarrior Combo O Commander
The keys get loaded, but they get loaded 5 times!
I am told that the name for the device is "Code Mercenaries KeyWarrior Combo O Commander" ,
but the message also shows 5 times!
What am i doing wrong?
Whats confusing to me too, is that i cannot use
loadusr -W hal_input "Code Mercenaries KeyWarrior Combo O Commander" , that one won't work, only without " , its accepted.
As far as i know, you should always use " when there are blanks in a name / path.
Thanks in advance, Tom

I do not really understand why,
but when i load the usb-mpg via Vendorkey+Productkey and -K option, all works fine.
Any disadvantages loading the keyboard via vendor/productkey and not via name?

Hi folks,
i tried remapping the keys on my usb-MPG with keyd, but i struggle importing them into the hal.
Is there a prefered way of remapping keys for linuxcnc and do you have a link to a turorial or a manual?
Thanks in advance,
Greets Tom

Do you have the hal_input component working and the pins created?
Maybe show us what you have got and then tell us what is not working. Otherwise we're just guessing.

Hi Aciera, nice to meet you!
My Problem is: My USB-MPG sends weird keys, Alt /M , Alt / - , Alt / % , Alt / # , Alt/= , F10 , F11.
Alt / % sends Alt + Shift + 5 , which makes it "interesting" to grab...
F10 and F11 opens the menu and toggles between fullscreen and windowmode.
So, at first i have to somehow keep these keys from interacting with the UI of Linuxcnc, ONLY interacting with hal_input.
I triedi triednone of these stops interacting with my ui..
What i did so far, i grabbed the USB-name, and vendor and productkey of my USB-Davice.
I wrote a UDEV rule which worked after a bit of confusion.
i loaded the device in the halfile ( of the sim so far ) and i could see most of my keys turn yellow in the halshow.
So my first attempt ( asking the AI, which was not my best option when i think about it now ) was to remap the keys with keyd.
I wrote a default.conf to remap the keys. What happened?
The keys which send F10 and F11 do no longer affect ma ui! No toggling window to fullscreen.
But i struggled at importing the "virtual keyd keyboard" into LinuxCNC.I would like to use " , but these don't work for me, i do not know why ( see above )
One of my Problems:
I cannot load the keyboard via "name",does NOT work..works! As far as i know, i should use " whenever i have blanks in a filename / path / device.
I do not really understand why..
Thanks for any help in advance!
Honestly, i tried with AI-support, but this only calmed my mood because our jobs are safe for a looong time, so crappy answers..

Not sure I understand you correctly but it you have the pins in your hal reacting to your pendant keys wouldn't you just need to connect those hal pins to the respective pins of your gui?

Hi Aciera,
you are right, but i see almost any buttons of my keyboard, i can not figure out how tog et the rest of them.
Another problem is, when i press Button "Z", the menu in LinuxCNC shows up, because "Z" sends "F10" ( or was it F11 ) which brings up the menu. Another Axisbutton toggles between Windowmode and fullscreen of LinuxCNC UI, which is not what i would call a reliable system..
So i think i have to remap the keys send by my keyboard, or is there another solution to this problem i don't know about?
Thanks in advance, Greet, Tom

Sounds like you are not acually grabbing the right device.
What GUI are you using? Gmoccapy offers the option to disable keyboard shortcuts.
