Why preliminary? I've run at least 2 studio quality DA converters over USB on the Parallella, except there are some alsa difficulties that make the standard board in my case not work (without some software upgrades and a little hacking) and the HDMI tos doesn't work for me and some others.

Thanks for sharing the video! Curious as to whether you have a use for the Epiphany in mind with such applications?

Cheers,

Andrew

Very nice presentation and video! Would be even better if it was using the Epiphany.:-) Any plans plans to do something fun with the Epiphany?

Thanks for the encouragement. I'd certainly like very much to take a close look at the Epiphany when the SDK will be supported under Windows.

Love my Parallella, congrats for the +10,000.

Many thanks to Andreas and the team, great board!

I tried to attach .zip source code to this post but got a: "Sorry, the board attachment quota has been reached."
Please can you reset my quota, thanks.

The only setting I could see was for the whole board and this was set pretty low, so I've increased it.

Thanks for sharing the video!

Cheers,

ptc,
Wow, what an awesome project! Very impressed by your breadth. FPGA, DSP, coding, soldering, etc Is there anything you can't do? :D

Thanks Andreas.
My wife deserves all the credit as she's putting away a lot to let me live my passion.
