PCM3070 Equalizer application

Raul Atkinson
Prodigy 50 points

Hi,

I have the PCM3070RHBEVM-K-CB connected to the USB-MODEVM interface board.

The boards power up and I can use the application (running on windows 7) to pass audio through with the by-pass configuration.

However that's the only application I can get to work.  NONE of the other applications work.  All I get is silence.

I am particularly interested in the equalizer application.  Is there any special setup I need to run to get the equalizer application to work.

I see USB activity and hear clicks and snaps on the speakers when the USB is active,

Thanks!

    Hi,

    I got the equalizer in the PCM3070EVM-K to work.  However it only works with the digital interface from the USB.

    When I try to set up the analog path through the 3070, I get silence.

    Also I noticed the equalizer app is writing to reserved registers.  Perhaps the documentation I have is old?

    Is there documentation available on how the analog A2D interfaces to the DSPs?

    Thanks
