Lark Studios Hardware interface

Category: Hardware
Product Number: ADAU1861


I have purchased ADAU1861 and just for checking the hardware interface with software, I tried connected differential mic with ADC0 and one speaker at the O/P port and run the experiment model with AD0 block connected to Output block in lark studios. All the register settings I have done and downloaded to target but I am facing the issue that I am not getting anything at the output from the speaker.

Can you please help me to understand what I am doing wrong, I checked all the setting and gone through the user guide and getting started user guide present in lark studios software help section. I could not find any other material related to lark studios and EVM nor any videos on the internet and not even any examples.

If you have any sources for the material and videos to understand lark studios software please share with me.



  • Hi Simram,

    Everyhing you mentions seems right so I would suggest to do the following. First could you copy the default jumper configuration explained on "EVAL-ADAU1860 User Guide"

    and then go to the installation folder. tipically it would be "C:\Analog Devices\Lark Studio\Examples" and open the example called "lark-demo-adc-dac.larkproj" and download the configuration.

    That should work out of the box.
