Hi,

You could take a look at the Audio example project in Processor SDK RTOS:

Is there any other example code?

I found 'MCASP_Audio_lcdkOMAPL138_c674xExampleProject', but it is difficult to analyze in DMA mode.

Hi,

I am afraid there isn't other example available. Processor SDK RTOS provides only McASP & McBSP examples.

Hi,

I want to increase the number of data lines I2S mode in the MCASP_Audio_lcdkOMAPL138_c674xExampleProject project.

EX) TX: AXR(13), AXR(15) / RX: AXR(14)

Where should I modify my code to add AXR data lines?

Hi,

Have you tried modifying the McAsp channel parameters in mcasp_cfg.c:
   {
        RX_NUM_SERIALIZER,                    /* number of serialisers      */
        {Mcasp_SerializerNum_14, }, /* serialiser index           */

TX_NUM_SERIALIZER, /* number of serialisers */
{Mcasp_SerializerNum_13,},

Best Regards,
Yordan
