AD535_open

AD535_open

Opens codec channel

Function

 

AD535_Handle AD535_open (

 

 

AD535_Id *myId

 

);

 

Arguments

 

myId

Pointer to an object of type AD535_Id. This object

 

 

 

contains the McBSP channel number and a McBSP

 

 

 

handle.

 

 

 

C6711 DSK

 

 

 

If you want to use the local codec, you may pass

 

 

 

the predefined pointer AD535_ON_6711DSK. If you

 

 

 

want

 

 

 

to use another codec you must create your own

 

 

 

AD535_Id.

Return Value

 

AD535_Handle Handle to newly opened codec channel

 

 

 

Note: If the board does not support this function, it will

 

 

 

return the invalid handle INV.

Description

 

Before a codec channel can be used, it must first be opened by this

 

 

function. Once opened, it cannot be opened again until closed. See

 

 

AD535_close().

 

Example

 

To use the local codec:

 

 

AD535_Handle hAD535;

 

 

hAD535 = AD535_open(AD535_ON_6711DSK);

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; hAD535 = AD535_open(*myId);
