(SOLVED - maybe) How to get an underscore in a pin/parameter name?

Create your component and then pre-process

Then edit the generated C file to have your pin names.
Then compile and install

But, on a typical LinuxCNC intallation you can simply change the [HOSTMOT2[BOARD string to be your hm2-7i76 module and edit the loadrt lines.

I don't suppose hm2_test is any help?

Just cos a underscore can be used does not necessarily mean it should.

Not at all helpful.

Perhaps you missed where I showed doing exactly the same...

That doesn't seem to be exactly the same thing at all. Perhaps you failed to read my recipe?

(And you will find that you get the problem you describe any time that the component name and the file name do not match, so if you didn't change the component name in supply.c then it simply won't work.)

It looks promising. If it allows me to run a config offline it is a viable solution.

That's what I was trying to say, the file name and component name have to match, hence the coding error.
What is the thing with the dash replacing underscore if you know ?

Part of the (widely ignored) canonical interface specification.

It is documented somewhere that all HAL pins should use hyphens.

Having tried it, I am not sure if any of the test_patterns actually load.

For example.
