How to display the value of the int variable from the hal_parport.c file in the was created by drzasiek90
Hi, I'm compiling my own version of LinuxCNC and making some changes to thefile. I would like to be able to display the value of a variable in the Axis panel in a way similar to how spindle speed is displayed using a HAL pin. Can someone guide me on how to achieve this?

You may want to elaborate a little more.
What variable ?
Where is coming from ?

Maybe create a new HAL pin or parameter and set the value of it inside your new comp.

I create a global variable in the source file that takes certain values in certain situations. I compile linuxcnc and run. I would like to be able to view the value of this variable while the program is running.

Create your variable in the HAL structure and assign it to a parameter (you can copy the structure of the other pins / params)
Then you can use the existing HAL tools to monitor the value, including displaying it in GUIs.

No, I've already done it.
I am able to view the parameter in tools.
However, I would like to display this value permanently, but using pycvp it is probably not possible - so far I have not succeeded.
Using pyvcp I am successfully displaying the hal pins but the hal parameters are not working.

Oh ok, you want to modify Axis to display the value ?

(Which means that it needs to be part of the hal_malloc data and needs to be a pointer to a pointer)

PyVCP can only display items that can be "net"-ed to the PyVCP pins in HAL. So you will need to create the variable as a pin, not as a parameter.Using pyvcp I am successfully displaying the hal pins but the hal parameters are not working.

If necessary.
However, I'd prefer to do without modification by adding a panel via pyvcp.
I am looking for a simple method so that it is easy to replicate.
