Halui Component

phillc54,

I finally got around to trying your code by pasting it into a .axisrc file. When I run Hal Configuration within LinuxCNC, I don't see the step-activated pin anywhere in the tree. Should I be able to see it somewhere?

Hi,

It was Python code :
You would see this new pin by the name : step-activated

Yes, it should appear as axisui.step-activated

Sorry to further bother you guys with this but I'm still having issues getting the code to work. I created an .axisrc file with the sample code copied into it. I saved the file in my home/username folder location. Here is a screenshot:


After running Hal Configuration in LinuxCNC, I can't see the step-activated pin in Axisui. Am I missing a step?

Do you see any error messages if you start LinuxCNC from the command line (command "linuxcnc" )

No, it starts up without any issues.

How about if you put a deliberate error in the .axisrc file?
(Just to be sure that it is actually running)

I'm guessing you are using LinuxCNC 2.7, if so then the user_hal_pins() function is not available.
[strike]If that is the case then I think you can use the function user_live_update() but will need to create a new component like:[/strike]
Create a new component with this in .axisrc in lieu of the user_hal_pins() function: This should give you a pin named stepstatus.step-activated

Edit: Only took two edits to get it right, I don't use 2.7 enough...

He is using 2.7.14. I do recalled you or someone mentioning that the .axisrc workaround works on 2.8 or 2.9.

Everybody,

Thank you very much for the assistance! I finally have it working. I had to make some small modifications to the .axisrc file after stitching it together with the latest suggestions. I have attached it below for future reference if any else may run into the same issue.



I'm going to try and hijack the LinuxCNC Run button so that I can use it to reset the step_activated bit once activated.
