TCP 5-axis kinematics

I need quick help.

Im trying to write out values from kinematics trough HAL pins:

this is located in" rtapi_app_main"
if((answer = hal_pin_float_new("xyzbc-trt-kins.oma",
HAL_OUT, &(haldata->oma), comp_id)) < 0) goto error;

this is in code:
*(haldata->oma) = 11.11;

when looking/watching from HAL configuration in linuxcnc only shows 0.0

it's compiled and im using this file.. and it does not give error when compiling.
Also I tried HAL_IO, HAL_IN no difference.

How can I write values to HAL pins????

What you have ought to work, but there is a bit more you need too (You may be doing this, but haven't shown that part of the code) One thing is that the haldata struct needs to be hal_malloc-ed

Yes if you mean this line:
haldata = hal_malloc(sizeof(struct haldata));

That is located in rtapi_app_main() before introducing HAL pins.

Jussi

And is oma in the haldata struct (I can't open .rar files to check. (And I am on a Windows 10 PC at work))

Is the code that is setting the oma value in a function that is being used? I am a little unclear which of the forward and inverse kins subroutines get called when. I think I would be tempted to add another HAL pin that changes state whenever forwards kins or reverse kins runs.

Ok

Here is c file of kinematics.

Nothing looks particularly wrong (other that you probably need HAL_OUT as HAL_IO is only for very special and unusual cases.)

Is the haldata->oma pin never changing vale at all? I think that that caon only really mean that that code isn't being run.
Do the print messages etc all happen as expected?
