Part Number: TLV320AIC3256EVM-U

Hi!

 I want to do a test that the voice from mic is converted by ADC  and  it can be heard by headphone with the help of  PurePath Studio  software and TLV320AIC3256EVM-U.  I choose the Dec4xIn component  as input but it does not work.  What other ways can I use to slove the problem?

    Hi, Maolin,

    You need to configure the codec to use the Input Microphone of the EVM (IN3L/R) as the ADC input source, by default in PurePath Studio, IN1 is selected as the ADC input (Line IN on the EVM). In order to change the codec configuration, you can update the System Settings Code to change the input for the ADC, this code is available  in the properties Window of PPS when clicking on the framework. For more information about how to change the System Settings code in PPS, please refer to this FAQ. 

    Best Regards,
