(at this time i study the HAL tutorial , a little bit dry but .... )

where is it posible to change gpio to Inmux ?
i havent found it in the mashine .hal or . ini

With linuxcnc running.
Open up a terminal and type.
halcmd show all hm2

That should give you a list of all the pins.

You edit the hal file. With a text editor.

hi,

i think i am to stupid to fin these gpio.000.in in the .HAL
or what did i do wrong ?

I'm sorry got it wrong.

[edit]
Looking at your .hal file it seems that you have not used any digital inputs or outputs yet:

so apparently you have not declared any in the pncconfig tool. So you can just declare by adding them manually to your .hal file using the form:

hm2_7i95.0.inmux.00.input-00

As an example for input number 0.

The suggestion from CliveS was a good one.

Start LinuxCNC with your current config.

Open a terminal.

Type: "halcmd show pin > pins.txt"
Type; "halcmd show param > param.txt"

And then keep the two files as reference.

For the pins that are _not_ hosmtot2 (hm2) you can generally find the documentation for what they do here: linuxcnc.org/docs/2.8/html/
in the section "Realtime components and kernel modules" and the section above that.

So, fo example, to find out what a "halui.xxxxx" pin is for, look in the "halui" manual page.

The exception is "spindle.xxxxx", "axis.xxxx" and "joint.xxxx". Those all belong to the "motion" module.

Don't be too overwhelmed by all the pins, you won't ever need 90% of them.
