Hi
I am trying to set a hal pin from gcode. I can read a pin but I am having trouble setting one.
This is my attempt
the error is " Internal error: could not assign #<_hal[hurcotc.move-done]>"

Hi
They are read only.
The FEATURES=12 or whatever gives you access to the values, but you cannot change them, that would be the Holy Grail.
If the pin can be written to, you can do it from a user M code
halcmd setp <pinname> value type thing
Whether it is linked and what type of pin it is is going to determine if it can be written

Damn that sucks. I will have to rethink. maybe use a timer to set a pin.

There was a way to wait for a signal in a user M code that uses a shell script. I cannot remember however how to do that. Any suggestions

But to set a HAL pin value from G-code the simpler way is to use:
www.linuxcnc.org/docs/html/gcode/m-code.html#sec:M62-M65
and net the HAL pin to motion.digital-out-00 (or whatever)
