I wouldnt think the connected PC has to be in any way powerful, is that correct, since all the actual processing is performed on the DSP? is it effectively a web interface? I would have thought that would be the way to do it, as a web interface, that would make it truly platform independent

That's correct, the PC doesn't need to be powerful. Actually the application should run smoothly on any old laptop (well maybe any post 2000...).
A web interface would be nice indeed - but don't believe that all web stuff is cross-platform or even cross-browser. Ask any web designer ...
For this present project, the interface is a light executable that's running natively in Windows and Linux - with a Mac build following soon.

Hi,

please count me for one with analog volume control.

done web design, design is my background years ago. but I mean something like a java applet. its only stupid proprietary plugins and bells/whistles that cause issues, like flash, silverlight, all those type of media plugins owned by companies that love to control people's spending. java, HTML3 or XML would work a treat.

good to know the software isnt far away, cool

That's cool, thanks for your interest!

Here's a little dialogue that allows setting some analogue output properties.

With this dialogue, the user can select either slow or fast roll-off DAC interpolation filters. After clicking the OK button, the change takes place immediately and the board will remember the setting.

If the board has the analogue volume chip installed, then the user can also set the nominal output level anywhere between 1 Vrms and 6 Vrms in 0.5 V steps. In absence of the analogue volume chip, this option is not available and the nominal output is 1 Vrms.

Have you made a decision about the u.fl connectors yet ?

Hi Dahlberg,

I looked at adding u.fl pads carefully but ended giving up: it's a small board and I couldn't manage to place so many pads without disrupting the layout homogeneity achieved thus far.

There's however a positive side note: I doubled the amount of DGND pads so it's no major issue to plan u.fl adapters or wire the signals straight onto the board. Basically there's now one DGND pad for each high-speed signal line

I really like the direction this project is heading to.

Analog volume control pretty please :-)

That's great, thanks for the feedback!

I got news regarding availability. The PCBs are now into production and I'm expecting the first assembled sample by mid-November. So there's a bit of a delay, due to troubles for sourcing some parts. Sorry for that.

I also have the final price of the boards now:
USD 280 for the board without analogue volume control
USD 315 for the board with analogue volume control (CS3318)

Add 15% VAT for buyers in UE.

Best,

Nick

Hi Chapark,

I'd like to make a reservation for one board with the CS3318, thanks,

About pricing. Are You shipping from Australia? Wouldn't there be shipping costs also?
As for me living in EU (Sweden) The actual price would be USD 363 + shipping + import duty (17%?) and Swedish VAT (25%).
My estimation USD 550 or SEK 3800?
