M-code to toggle macrobutton not working on QtDragon

       Hi,
I am trying to assign to a macrobutton in QtDragon an o-word script that would allow me to toggle the button to switch on and off a laser.
The laser is connected to an output pin (hal_pi_gpio.pin-10-out) and this pin is connected to a signal (laser-on).  But, it doesn't seem to work. Enclosed are the custom M100 macro (to obtain the actual value of the output pin) and the o-word subroutine called by MDI-COMMAND = o<laser_on> call. Any idea why this won't work. Any suggestions how to do this?  Many thanks !!

Is there any indication of something working when you press the macro button?

What does this line mean? (doesn't seem valid to me)o<hal_value> include "/tmp/gcode_var.ngc"

Hi, to be really honest, this line came from ChatGPT, but indeed, I am still trying to understand where this comes from . Didn't found anything in the docs describing this include thing. What I am trying to do is to pass a variable from a macro (state of output pin) to a subroutine. Since subroutine variable can only be flaoting points, I changed the VALUE in the macro to be 1.0 if if true and 0.0 if false. Now the macro does work, however the subroutine gives the error message that there is a wrong command in the subroutine.... must indeed be the 'include' thing

Hi, I think I am progressing, but not completely.Enclosed my new M100 and subroutine files.The purpose is to assign to a macrobutton in QtDragon an o-word script with a MDI-COMMAND that would allow me to toggle on and off a laser. (I have a 10W from Creality), besides my spindle that will of course be switched off.The laser is connected to an output pin (hal_pi_gpio.pin-10-out) and this pin is connected to a signal (laser-on). In the subroutine, I want to check what the status of this output pin is and then switching OFF if it is ON or switching ON if it is OFF.Since the hal-pi-gpio is connected to a signal, I cannot use getp and are using gets. But since subroutines do not accept halcmd gets commandes, I made a macro (M100) to fetch the status of the hal-pi-gpio. So far so good.Now when pushing the button, M100 does his job and stores the status of the hal-pi-gpio in a variable (

In the meantime I solved the issue. I connected the Raspberry Pi gpio output pin to motion.digital-in-00 and now I can read this RPI output pin with M66. No need for a macro anymore...
