F28M35E20B: Pointer and Struct

Long Pham Tan

Part Number: F28M35E20B
Other Parts Discussed in Thread: C2000WARE, MOTORWARE

Tool/software:

I haved read your project "C2000Ware_MotorControl_SDK_5". In file libraries\observers\esmo\source\esmo.c There is the following code:

Void ESMO_resetParams(EMSO_Handle handle)
{
ESMO_Obj *obj = (ESMO_Obj *)handle;

obj -> pll)ui = 0.0f;

....

}

WHY don't you just use the handle variable instead of creating another pointer?

Hi Ozino,

Maybe my question above may make misunderstand,

I just want to understand coding standard with object C Ti style with many modules in SDK or motorware (not about eSMO modules)

For example :

Void OBJECT_resetParams(OBJECT_Handle handle)
{
OBJECT_Obj *obj = (OBJECT_Obj *)handle;

obj -> pll)ui = 0.0f;

....

}

--> Why inside the function body: we have to use "obj" pointer why don't use "handle" directly, "obj" and "handle" I see that there is no difference.

Hi Long Pham,

Yes, this is not necessary, you can directly use the handle variable. This is just a TI custom.

Thanks,

Jiaxin
