execute G code line by pinchange

Hello...
I looking for way to execute Gcode line (or subprogram O<myfile>) triggered by pinchange.
The pinchange came from userspace python component so maybe it's doable from within component.

Thanks for hints.


p.s.
actualy entering MDI command (from component) is ussable to.

Hi

The first way is to use halui mdi
halui.mdi-command-<nn> (bit, in) -
www.linuxcnc.org/docs/devel/html/gui/halui.html

What ever you connect to the halui pin will trigger the associated mdi command in the ini file when it goes high

If you want to do it from a component, probably easier, see this recent thread for a component executing a series of MDI commands read from a file
www.linuxcnc.org/index.php/english/forum...b-in-position-signal

python has a system() function I believe, so you can do similar, triggered by a pin in the component connected to whatever your trigger is.

regards

halui.mdi-command-<nn>

... just perfect. (I already used that but forgeted...)

Thanks
