We have a big problem with TI5402 connect AC97 codec . We used AD1885 (AC97 device) . We used Mcbsp0 to connect AC97 codec . Setup AC97 codec as slave mode , the DSP timeing will ok . But AC97 codec do not have any response ! If we make AC97 codec as Master mode , that meant BCLK(R/

Hi friends, I program the c5402 in C language. I see in the codec example that the sampling rates i can configure the codec are only 2kHZ-16kHz using the available function. How can I make the codec to sample at 500 Hz? Is there some other C-callable function which I

Hi Everybody! i have a trouble: i am trying to use the audio codec of the board, but it has an analog stage before the codec (50ad) that eliminates DC (i see on the schematic "5402_DSK_schem.pdf"). If i need this DC, it would work if i short-circuit the capacitors. This als

Hi All, We are developing basic analog phone using TMS320C54CST and MSM7716 as codec. Codec is going to be connected at McBSP0 for audio data and McBSP1 configured thru SPI for control data. I need to know how we can configure the McBSP for our codec (MSM7716), we have tried to configure but looks like its not working for us. So any suggession how to do this or ...
