New component for keyboards and panels.

I have two keyboards working with the 7i73. One of 5x4 that I use to generate HAL pins, this works without problem, the other of 4x8 I am using to simulate keys with sendkey. This one also responds, but the problem is that it responds very slowly when you press a key or you have to do it several times until it responds. Also, most of the time it stays as if it were pressed and starts typing the same character and only stops when another key is pressed. What will be the problem?

andypugh please help.

To be honest, I don't know what the problem is. It's a user-space HAL component and it sounds like it just isn't getting enough CPU time.

Are you running a base thread? How does the base thread execution time compare to the base thread period?

Thank you for your response,
I'm running linuxcnc on a raspberry PI 4, with a 7i92 + 7i73.
but I really don't understand what you mean, could you explain?

If you are running with Mesa cards then you probably are not running a base thread.
It's unlikely that you are running out of time, but comparing the value of the hal parameter servo-thread.tmax with the servo thread period might give some idea how much CPU time is left for other services.

960575 does seem worryingly close to 1000000.

I wonder if there is any scope for pruning your servo thread tasks?

halcmd show funct

Will give a snapshot of which servo-thread functions are using a lot of time.

This is what appears when I run halcmd show funct.  I attach the entire file by running just halcmd show.

Thank you COFHAL, for share link to here topic
this is my old topic  forum.linuxcnc.org/49-basic-configuratio...ey-how-to-map-number

I start with try from link :  linuxcnc.org/docs/2.8/html/man/man1/sendkeys.1.html

all look good  except  ls -l /dev/uinput
In link show  : crw-rw----
But my Terminal show  : crw

---

      only  (no rw)

I try open linuxcnc from terminal 

cannot /dev/uinput. Suggest chmod 666 /dev/uinput

How to can access chmod 666 ?



FYI:
- I use 7i73 matrixkey 8x8  (good work)

- I already add loadusr -W sendkeys config=16t2
