TMS320F280039C: InstaSPIN library interface.

Part Number: TMS320F280039C

For project purpose I need to gather the knowladge, how to interface InstaSPIN library in Motor Control SDK for C2000.
I've found out it could be interfaced by MOTOR_Vars_t structure fields, however "Motor Control SDK Universal Project and Lab" Guide doesn't contain full description of that fields.
Is there any source from which I could get that description?

    Have you looked at the actual InstaSPIN-FOC User's Guide in addition to the Universal Lab guide? It has more details about library interface and function.

    Based on Universal Motor Control Lab the main way of interfacing between user and lib is by MOTOR_Vars_t structure's fields. 
    Fields are periodically (in interrupt as I understand) processed and updated. 
    However in Motor Control Lab User's Guide (referenced in  InstaSPIN-FOC User's Guide) there is only partial explanation, what particular fields are. 
    I wonder if there is some knowledge source explained all that fields.

    I guess MOTOR_Vars_t is defined by the lab (specifically motor_common.h) rather than the InstaSPIN-FOC library actually, so it does make some sense that the InstaSPIN UG wouldn't cover it in much detail. It does contain pointers to things that are defined by InstaSPIN like estHandle, userParamsHandle, etc...

    So that said, I don't think we have a document that specifically describes each parameter of MOTOR_Vars_t. We mostly just have the comments in motor_common.h and the variables within it that are specifically called out in the lab guide.
