accesing McBSP duplex mode using DMA? - Swarna Kumar BA - Oct 19 6:43:00 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. swarna ------------------------------------------------------------- Swarna Kumar, Ittiam Systems (P) Ltd T +91-80-2237760 The Consulate, 1 Richmond Road, F +91-80-2237905 Bangalore 560 025 http://www.ittiam.com ------------------------------------------------------------- |
