CCS/TMS320F28069F: Motorware est.h using user #defines?

Tool/software: Code Composer Studio

I am using a F28069F with CCS 7.3.0 and motorware v1.01.00.18. I was trying to make a couple different motors "hot swappable". I.E. I was planning on having parameters for both compiled in and then initialize the user params structure with the motor I selected from a custom GUI. This way I would not have to recompile and re-flash the chip every time I changed motors. I was having some success with this when I think I found the provided estimator header file (est.h) is using some motor and user #defines for some calculations? I do not have access to the actual estimator functions so I was just wondering if this was truly the case? If so, how is a pre-compiled function (I think it's pre-compiled to an obj and the linked?) using a #define I set? Finally, in anyone's opinion, is what I'm trying to do out of the question? Thanks to everyone for your help and please let me know if I can provide an additional information.

I'd use preprocessor directives

#if macro_condition
   statements
#elif macro_condition
   statements
#else
   statements
#endif

That's not related to est.h and FAST estimator, the #if or #ifdef is condition compile, have to re-compile and re-program the code to support the different motor. That can't support "hot swappable" as you want.

You can set the parameters to the gUserParams struct for motor, and then call CTRL_setParams() to reset the motor parameters for the estimator.

Sorry for the late reply. This is what I've come to find as well. Thanks
