Re: VS1010 USB Audio with Mic

I got it working! I had to pull all power from the board and the disconnect the uart to get a full power cycle. I did not notice that there was a 4.5v source being provided by JP3. Once I put on JP3 and JP16. I got a constant values on both channels of zeroes for left and right. I then pulled all po...

Re: VS1010 USB Audio with Mic

Thanks Hannu! This is a good example but it does not work with the V2.0 vs1010 development board that has the AK5720 codec. :? FYI - The datasheet for AK5720 indicates: The AK5720 should be reset once by bringing the PDN pin to “L” after power-up. In slave mode, reset and power-down are released on ...

I looks like I could use this as a line input and forward it as such on the USB with the right code update to the usb descriptors. I am working with the line in/ line out example and there is no audio...

VS1010 USB Audio with Mic

In reference to the VS1010 Development board: I am looking at the feasibility of adding the microphone end point to the USB Audio driver.
