Hi all I use dsk6711 with a doughterboard with 2 codec on it. my codecs generates frame sync. pulses for McBSPs. each coded samples from a sound sources and record the samples and put the received sample on the other codec. The structure is like this: input_signal1 --> codec1 --> McBSP1 --> McBSP0 --> codec0 --> out_sig0 out_sig1 <-- codec1 <-- McBSP1 <-- McBSP0 <-- codec0 <-- in_sig0 writing to McBSPs handled by polling(by checking the SPCR bits) and read from them by interrupt on frame sync. pulses from codecs. Now the problem is that each channel works well, but when we use 2 channel at the same time, the system does not work. I would be pleased if any one could help me. Regards Habibi |
