This 

AD535_Id

 structure is used to allocate a codec channel. You create

and initialize this structure, then pass its address to the 

AD535_open()

function. Also, this structure allows you to access to the McBSP handle
through the 

AD535_getMcbspHandle()

 function after calling

AD535_open()

.

If you wish to use the AD535 codec implemented on C6711DSK you can
pass the predefined pointer 

AD535_ON_6711DSK

.

The predefined pointer 

AD535_locald

 associates the codec to the

mcbsp0 directly. It’s not necessary to define 

AD535_Id pointer.

mcbsp_no

 variable is set to 0 (mcbsp0)

See source file bsl_ad535.c

/* the codec of C6711DSK use the predfined pointer

AD535_ON_6711DSK

*/

AD535_Handle hAD535; 
Mcbsp_Handle hMcbsp;

hAD535 = AD535_open(AD535_ON_6711DSK);
hMcbsp = AD535_getHandleMcbsp(hAD535);

To set up your own AD535_Id, for example:

/* set up a codec using McBSP 1 */
AD535_Handle hAD535; 
AD535_Id myId; 
myId.Id.mcbsp_no = 1;
Mcbsp_Handle hMcbsp1;

hAD535 = AD535_open(*myId);
hMcbsp1 = AD535_getHandleMcbsp(hAD535);

Note: You can also use the Mcbsp1 if you haven;t opened an AD535
handle with the predefined 

AD535_ON_6711DSK object.
