TLV320AIC3120EVM-U: Hello all.. Can somebody expertise in audio please suggest how to acquire the audio data for the above mentioned codec. ?

Part Number: TLV320AIC3120EVM-U
Other Parts Discussed in Thread: TLV320ADC3140, TLV320AIC3120

I have to interface codec to stm32f4 controller,

Can somebody just brief how to acquire the audio for this codec using codec control software. when plugging into J2-Mic In.

I dont find any useful example code that could help me anywhere ,not even in the datasheet and user manual?

this is just beginner EVM i have for now,, but the original project involves TLV320ADC3140.

Any faster response could be much appreciated.

Thanks all in advance. 

  • Hello Shweta,

    There is an initial script that is loaded into the device when the GUI is opened and configures the device for both record and playback. You can view this initial script by going to View --> Init Script. Here you can view what is configured.

    Are you trying to record and not getting any data out?

    >>I have done the whole ,I could only do the playback excercise from youtube,mediaplayer and listened through J4 ,

    but I didn't get the exact how to record on this EVM -board 

    I have tried ACEV-1A EVM user manual and the datasheet of tlv320aic3120 section page 57 and 7.3.11 how to record.?

    >>And there is another query Is there any embedded library for tlv320adc series.?
