Re: EVM OMAP L137 - sample rate -accessing McASP with DSP/BIOS app running under Linux

Hello Mariana,

I have another question on the audio setup for you. I need to adjust the sample rates on my application. The hardware description of the codec chip indicates that it is capable of 96Ksps. Can I just modify the Sample Clock rate values in the Audio_ChannelConfig structs which were defaulted at 44100 in the sample app to change sample rates, or do other driver settings elsewhere have to be changed if I start to change sample clock rates as shown here:

Thanks!

Richard

Audio_ChannelConfig audioChanParamsIN =
{
   /*  channel 0 (RX)                                            */
    (Ptr)&mcasp_chanparam[0],
    {   /* codec [0]                                              */
        {
            //44100,  /* sampling rate for codec */
            48000,
               30,  /* gain (%) for codec      */
             0x00,
             0x00
        }
    }
};

Audio_ChannelConfig audioChanParamsOUT =
{       
    /*  channel 1 (TX)                                            */
    (Ptr)&mcasp_chanparam[1],     
    {
        /* codec [1]                           */
        {
            //44100,  /* sampling rate           */
            48000,
               70,  /* gain (%) for codec      */
             0x00,
             0x00
        }
    }
};
