AIC23 codec - genesisleo - Nov 23 3:51:00 2004





Hi,

I understand that the c5510 DSK uses a AIC23 stereo codec for input
and output of audio signals. However if instead of feeding an analog
input signal, can I feed in an array of digital inputs from the
processor to the codec so that it can be converted into analog
signals? Do I need to use McBSP to transfer my array elements to the
codec?

I would appreciate if anyone can provide with simple codes. I have
tried looking for information but I have no idea how to handle the
McBSP and to link it between my array and the codec.

Thanks.

How do you think that the data goes back, out of the
CODEC? It's a stream of digital data, transmitted from
the DSP to the CODEC, specifically to the onchips DAC.

OF COURSE!!! > I would appreciate if anyone can provide with simple

I think that the same code could work. Let's assume
that you have some interrupt servicing routine where
you get the received data and then send processed data
back to the CODEC for ditigal-to-analog conversion.
Well, insert the data you want to convert to analog
RIGHT HERE!
