accesing McBSP duplex mode using DMA?

Started by Swarna Kumar BA October 19, 2001

Hi all
I want to use the McBSP-codec interface in the 54x dsk in full
duplex mode
using DMA.I tried to use codec_cont_play(), codec_cont_capture()
functions declared
in codec.h. I find that using these functions I can do only a half
duplex conversation
with the codec.The reason for this -probably- is both these functions
try to use the same
DMA channel.

Has anybody tried this?
Can I get any help in this regard?

thanks and regards.
