Adding USB Keypad was created by islander261
Hello
I am trying to add an USB keypad to used as an external jogging control. I am almost there but just can't get permissions correct to use it. Here is the key pad USB info:
I have created a rules file and placed it in /etc/udev/rules.d/joypad.rules.
When I do this it doesn't work:
And when I do this it does work:I can follow this with a show pin command that will overflow the terminal buffer with pins.
Now what do I need to do to get the permissions set so loadusr -W hal_input -KRAL XKeys when run from my HAL file will work?
TIA
John

halcmd: loadusr -W hal_input -KRAL XKeys
No input devices could be opened. This usually indicates a misconfigured
system. Please read the section 'PERMISSIONS AND UDEV' in the hal_input
manpage
<stdin>:1: waitpid failed hal_input hal_input
<stdin>:1: hal_input exited without becoming ready
halcmd: And when I do this it does work:
jd@plasma1 ~ $ sudo halrun
halcmd: loadusr -W hal_input -KRAL XKeys
halcmd:Now what do I need to do to get the permissions set so loadusr -W hal_input -KRAL XKeys when run from my HAL file will work?

Hello
Ok, I found the solution in a very cryptic message in another thread. I couldn't find instructions to do this on any of the man pages I looked at, only vague references to needing to set permissions no locations given. I had the permissions set incorrectly for the /dev/input directory and all it's children. The permissions need to be read / write for all users of the directories. I had tried this previously using chmod but obviously did not get it correct. I used the file browser and the open as root right click menu choice and then went to properties > permissions and made the change. It works now both using halrun and from halshow in my Gmoccapy gui.
Now I sometimes get error messages in the terminal when I start Gmoccapy but this is normal for me.

Yes, I intend to use the keypad for jogging and homing. I thought I needed to use the hal_input.comp to get pins to connect to. Is there another way?

Just plug it in. I did nothing.
It works on several systems with Linuxcnc i have, Just check the "num lock" on the big keyboard, i have it on the small one so i can toggle as needed.
Jog X Y Z, home, touch off, all work. Did not test anything else.

Thank you. I don't actually have a numeric keypad clone of the standard keyboard. This is what I have:
xkeys.com/xkeys/legacy.php
I have the 20 key version. It is configured to work with my old Torchmate 3 system right now so I don't want to reprogram it as I use it almost every day. I also hope to sell the TM system to someone who needs spares when I get my Lcnc controller up and running (close).
