Hi
I use Mesa 7i76 and limit switches in Normally closed wiring = when I start machine all switches are closed.
I would like to invert pin in HAL config file.
In file configs/custom.hal a wrote:but it does not work.
hm2_5i25.0.7i76.0.0.input-00 is the pin connected to min-x switch
Could you please help me? I am sorry I am beginer with LinuxCNC.
Thanks a lot.

For the inputs on your 7i76 use the pinfor the inverted state. (that is inplace of the regular input pin.)
hm2_5i25.0.7i76.0.0.input-00-not

because I got an error on:pin 'hm2_5i25.0.7i76.0.0.input-00-not' is not writable

Just curious, why would you want to logiscally have a critical input change state in software if you can even do that?
Why not create an output and tie it across the input and control the output with software. I do that to get by a limit switch during tool change. But I have another down the line for security also.

It is probably better to simply connect the correct pin in the normal HAL and accept that you won't be using Stepconf/PnCConf again, or run the wizard and invert it there.

Instead of guessing at pin names get a list of all pins like this
To get a list of all the Mesa pins make sure field power is on then open
a terminal and do the following. ~$ and halcmd: are not to be typed they
are the terminal prompts. If you add a config to the hm2_pci line it will
change the pins that show up.
~$ halrun
halcmd: loadrt hostmot2
halcmd: loadrt hm2_pci
halcmd: show pin > pins.txt
