Hi,

is there any example code for simple audio loopback using interrupt on c6748 lcdk  .

I found the more complicated edma on starterware, but not the simple interrupt driven.

Thank you

    Can you please refer to the following MCSDK audio loopback example ?

    Hi,

    Thanks for your post.

    I think, you could find McASP echo rCSL DSP based example available for omapl138 EVM which has C6748 DSP core in it, but you couldn't use the McASP Echo example directly, but however you would require platform level porting efforts to transfer the code from EVM and appropriately modify the h/w level code changes compatible to LCDK H/W platform.

    The McASP Echo register rCSL examplewhich provides a non-OS based example without EDMA of how to use the C674x DSP in conjunction with the McASP to receive and transmit 24 bit audio data from the TLV320AIC3106 codec.

    You could download the QuickStartOMAPL1x rCSL package from the below wiki

    http://processors.wiki.ti.com/index.php/QuickStartOMAPL1x_rCSL#Downloads

    From the above, please check the McASP Echo example synopsis from the below section:

    http://processors.wiki.ti.com/index.php/QuickStartOMAPL1x_rCSL#Example_Synopsis

    After installing QuickStartOMAPL1x rCSL package, you could see the McASP Echo audio example from the below specified path which is without using EDMA:

    ~\ti\quickStartOMAPL1x_rCSL\OMAPL1x\rCSL_examples\evmOMAPL138\DSP_examples\mcasp

    Kindly read the McASPEcho_README.pdf document available from the above installation path.

    Thanks & regards,
