Re: VS1103b Feedback Eliminator Demonstration Board

Hi Pasi,

Thanks for your response.

I'd be happy to have the source code in any format. I've previously implemented commercial VS1000 projects using your old command line compiler.

Regards, Chris.

VS1103b Feedback Eliminator Demonstration Board

Hi, I have a VS1103b Feedback Eliminator Demonstration Board. I've programmed it with VLSI firmware 'fbe_v110'. I'm using its on-board microphone.
