Seems so but I think It just gets the keys using a program called dump. You could try saving the dump to a text file and using that.
But also pyAutoGUI seems to do the same thing.

Man the last time I played with this stuff it was in the DOS days.

I think the keyboard module requires root.

I wonder how this would be treated in PREMPT_RT? I thought it basically removed any non-thread safe code.

I have not tried this but:
You should be able to write a component in Python to "stuff" data (single character or a string) into the keyboard buffer.
The first version of matrix_kb had this capability. But it did it by calling external kernel routines, and there was a worry that we had no way to know that these were thread-safe so it was taken out.
This commit is where I removed that code:
github.com/LinuxCNC/linuxcnc/commit/b494...c3b3790a457e1ed354c8
So if that was all put in a separate userspace component, the matrix_kb could look (partially) like a standard keyboard to the OS.
(In a userspace component there is no need to worry about thread safety)

userspace HAL components (In C and Python) work in all supported realtime systems.

So this example from the page above seems to work just from the python prompt
Auto types "Hello World" If you Select a text editor, it still types happily away
There seems to be a lot more you can do.
This is cool too
It would be pretty easy from here to make it a real keyboard...
import pyautogui
pyautogui.write('Hello world!', interval=0.25) # type with quarter-second pause in between each keyAuto types "Hello World" If you Select a text editor, it still types happily away
There seems to be a lot more you can do.
This is cool too
pyautogui.alert('This is the message to display.') # Make an alert box appear and pause the program until OK is clicked.It would be pretty easy from here to make it a real keyboard...

I am well down the rabbit hole, I have a HAL component that consumes the scancodes from matrix_kb or from a 7i73 and converts them to keystrokes.
I even had a prox limit switch connected via an STMBL drive typing the letter "c" in the terminal.
But then I broke it again, but it seems that it will work.
Watch this space.

So was it C for Curious or C for Cool?
Sounds exciting either way! I have a circuit board here waiting on one part before it turns into a shield for the 7i73... well hoping a mate will turn it into said shield cos he's much more into SMD soldering than I am!

Maybe one of these set up as a fourth axis (C Axis) to push the button on the keyboard for you

Not sure why, but that really struck me funny. Thanks
