Thread: Structure variable : how to set as generic ?

Hi All,

The below is the snippet of code which i am working on .
i am wriiting a switch case to set each of the variables in structure .

Note : REG_ADDR is address of some say (0x1000) .

i will get channel as input ,based on that i am setting the registers as shown in "Compute" function.

Code:

/* Some header definitions */ 
---------------------------------
struct REG_TYPE_tag
{
    int    COUNT;                     
}REG_TYPE_T;


typedef struct TOTAL_REGS_tag
{ 
    REG_TYPE_T         SM0;
    REG_TYPE_T         SM1;
 }TOTAL_REGS_T;

#define REG_ADDR (*( volatile TOTAL_REGS_T* )(0x1000 ))

----------------------------------------------------------------
"Compute" is a function which will just set the variable COUNT to a perticular value.
----------------------------------------------------------------------------

Code:

Void Compute(channel)
{  .....
 switch(channel)
 {
   case 0 :  REG_ADDR.SM0.COUNT = 10;
             break;
   case 1 :  REG_ADDR.SM1.COUNT = 10;
             break;  
   default : 
            break ;
  }
 }

----------------------------------
here in the above 'Compute' function if you see, only the
" SM(X) " is only changing in the case statements .
But is there a way where i can avoid "Switch" . and do like follwing
which will save me some lines of code

Code:

 Compute(channel)
 {
    REG_ADDR.SM[channel].COUNT = 10;  
  }

Because i dont want to write so many switch cases
Note: i have taken part of code only in this ..

Are there any ways which is better in this case ?

Thanks

Yes , i can replace with array of structures .
but ,my issue is something like template in c++ ,where i wanna do like the below

Code:

Compute(channel)
 {
    REG_ADDR.SM[channel].COUNT = 10; 
  }

i want to get rid of this
SM0 or SM1 and i want to replace with
SMX in "Compute" Function.
See First post for "Compute" Function.

Thanks
