Global Var

HI!!

I declared 3 global var, i call it inside diferent task and every execution this var should be updates but not to do it.
I have a 8051 under evaluation board.
Maybe can be a problem of my small micro?
What do u think about this?

Thanks

You show a global variable of an unknown data type.

You show that you send the address of the variable to a function.

You do not show the function implementation

Exactly what do you think will be able to deduce from this?

The data type is :

typedef struct {

real dState;            /* Ultima posicion             */
real iState;            /* Estado del integrador       */
real uMax,uMin;     /* Saturacion del actuador     */
real Kp;                    /* Ganancia proporcional       */
real Ti,Td;                     /* Cte, tiempo integral y derivativo        */
real Ts,Tt;                     /* Periodo muestreo, Cte. tiempo tracking   */
real Kwindup;           /* Cte. antireset windup                    */

} SPid;

The funtion implementation i think that is not important to resolve my problem. This is the top of the funtion:

real UpdatePID (SPid *pid, real SP, real PV, unsigned int AUTO,real Uman) reentrant;

real is int data type
