How to use digital inputs as a start, home keys was created by dzarek
hello
How to use the LPT port inputs as the keys to start, home, etc.
That are configured as digital inputs.
I have free pins and I do not want to attach additional adapted keyboard.

You should be able to use hal to take the input signal from the lpt to perform a task.
You should also be able to use hal with the pin to preform a MDI command.

You might want to take a look at halui (hal user interface).

ok, I add
in the file. ini
HALUI = halui
in the file. hal
net din-00 => motion.digital-in-00
net din-00 <= parport.0.pin-15-al
Now I want to connect motion.digital-in-00, together with halui.program.step (bit, in) and it is black magic for me:)
I think I need to do it in a file custom.hal, but each time the program does not start
this is my first approach to HALL so please forgiving with us
edit
it`s work

This might not be what you want. That sends a digital input to a "place" where G-code can see it.
If you want to, for example, link it to program-start then you would use
net startbutton parport.0.pin-15-in => halui.program.run
(or, you can split it onto two lines like you did above, if you like)
I have a feeling that there is more to running a program now than setting program.run to high, you might need
net startbutton parport.0.pin-15-in => halui.mode.auto halui.program.run
To set both auto-mode and program-run from the same button.
There are many other halui pins that might be useful to you.

Thank you very much for your help
I have one more question, how to change the status of the pin NO <-> NC?

If it is a parallel port input pin, use the in-not version of the pin.
eg parport.0.pin-15-in-not
eg parport.0.pin-15-in-not
