AIC23 Codec

Nguyen Van Hoang,

Do you have a DSK6713 and the support files that come with it?

You can tell me the difference between Uint32 fs=DSK6713_AIC23_FREQ_8KHZ and Uint16 fs=DSK6713_AIC23_FREQ_8KHZ (Book of Rulph Chassaing)

Are you asking what is the difference between Uint32 and Uint16? If that is the question, then you probably need to reference a C Programming manual or tutorial.

Are you asking why one form was used in one place the the other was using in a specific book? If that is the question, then you will need to tell us where the first place was, and how it was used in both places. One may be more efficient in code performance, but both may function the same way.

Data output  AIC23 codec what it? I want output AIC23 codec 16 bits signed, I have configure it how.

Please find a datasheet for the AIC23 if you want general information on it. If you want specific information on the one on the DSK6713, find that datasheet. General and specific information may be found at TI by searching for the part number.

I also am having trouble with PING PONG buffer. You can send me example it, explained the basic princeples of its operation.

There should be examples delivered with the DSK6713 that show how to use the AIC23 and to do simple audio input/output. These are usually done using PING/PONG buffer techniques. If you do not have the files, they may be available from the board vendor's website.

Please go to the TI Wiki Pages and search for "c6713 workshop" (no quotes). The training material you will find will help you with much of your task. There are lab examples that will help you, also.
