Yes the StateTag structure is added to the emcmot_hal_data structure
So Chris if you have a look at motion.c Line 335, there is a procedure called
init_hal_io that defines the motion pins. I'm sure you know this
Something like this should find the feed rate
Code:
emcmot_hal_data->tag->fields[GM_FIELD_FLOAT_FEED] // array index [1]
See:
github.com/LinuxCNC/linuxcnc/blob/andypu...c/motion/state_tag.h
And finally, a definition of what State tags does in that file
Code:
/**
* Tag structure that is added to a motion segment so that motion has a copy of
* the relevant interp state.
*
* Previously, this information was stored only in the interpreter, and as
* vectors of g codes, m codes, and settings. Considering that the write_XXX
* and gen_XXX functions had to jump through hoops to translate from a settings
* struct, the extra packing here isn't much more complex to deal with, and
* will cost much less space when copying back and forth.
*/
So let me know when you have a feed rate pin using State tags
