New component for keyboards and panels.

Yes, but to determine why you are not getting keystrokes, it would be
valuable to see if sendkeys works by itself...

I tested the 48 keyboard matrix, it works fine.
I want to use numeric keys and some keypads of the screen gmoccapy.
From HAL, I tested, run a specific task. loadusr -W sendkeys config=16t2
setp sendkeys.0.trigger-01 true. and check in hal show it works
Could you please provide an example Hal's component procedure that works with a matrix keyboard?
Thank you.
 

Could you post your configuration?

"Yes, but to determine why you are not getting keystrokes, it would be

If you take your test configuration and simply

setp sendkeys.0.trigger-01 true

a space keystroke should be created
(to do it again you would need to

setp sendkeys.0.trigger-01 false
setp sendkeys.0.trigger-01 true

The problem is that I followed the instructions given by andypugh in SENDKEYS to get permission to write to /dev/uinput and it wasn't working. I had to do it manually with sudo chmod 666 /dev/uinput. Since I'm using the rasperry PI4 every time I rebooted it, it again took away my permissions to write to uinput, I solved it by adding the command @sudo chmod 666/dev/uinput so that it runs automatically when the PI4 is rebooted. Now the problem is that according to andypugh's instructions, to see which event each key pressed corresponds to, the component must be loaded and and open a halmeter showing sendkeys.0.current-event. but this pin in halmeter always shows -1 even though if you write to the terminal the character corresponding to the key pressed.
