C syntax for CCS

OK

I have also tried the code below

extern struct CLARKE clarke1;

const Uint32 TxData[] =

{

(Uint32)&clarke1.As,

(Unint32)&clarke1.Bs

};

Now I get the error: incomplete type is not allowed

What is the proper syntax to create an array of addresses for structures such as the CLARKE?

Hi Gary

CLARKE it a type defined via typedef and not a structure tag.

From DMS clarke.h:
typedef struct {  _iq  As;          // Input: phase-a stator variable
                  _iq  Bs;            // Input: phase-b stator variable
                  _iq  Alpha;        // Output: stationary d-axis stator variable
                  _iq  Beta;        // Output: stationary q-axis stator variable
                    void  (*calc)();    // Pointer to calculation function
                 } CLARKE;

If within DMS's clarke.h the definition would be like this:
struct CLARKE {  _iq  As;          // Input: phase-a stator variable
                  _iq  Bs;            // Input: phase-b stator variable
                  _iq  Alpha;        // Output: stationary d-axis stator variable
                  _iq  Beta;        // Output: stationary q-axis stator variable
                    void  (*calc)();    // Pointer to calculation function
                 };

then your code would work

You should become more familiar with C syntax for the structures, and type definitions

BTW, you don't want to make an array of addresses by casting pointers to integers.  Your table should instead be something like

  const _iq *TxData[] = { &clarke1.As, &clarke1.Bs };

In other words, an array of pointers.

That isn't directly related to your compilation error, but it's an issue that might cause you trouble later.

Thanks for the sugestions. Very helpfull.
