[hpsdr] Naive question

[Bill Tracey]

Hi Alberto,

I do not believe there's anything in the hardware that is specific to the 
SDR 1000.  We do intend (I hope) to make the boards so that they will be 
useful with the SDR 1000, but they are by no means exclusive to the SDR 1000.

As to software, at the moment we are not doing a Windows (or any other OS) 
sound card driver for the board, so code that wants to use this board at 
the moment needs to be able to borrow the code I'm adding  to PowerSDR to 
get data from the board.   The code is in C and is pretty basic C so I 
don't think porting it should be a big issue.

The reasons we've not done a sound card driver for the board was expediency 
(I did not want to go learn USB and Windows audio driver architectures) and 
a general desire to keep Windows' fingers out of our precious data.

There's no known reason one could not do a sound card driver (probably 2 of 
them, 1 for the A/D and PWMs) and 1 for the TLV part.   There are folks on 
the list interested in making it look like a USB sound card  and I am not 
opposed to doing that as it would be nice to use our nice high performance 
gizmo with other code expecting to talk to  a sound card, but at the moment 
it is not something I am working on.

Regards,

Bill (kd5tfd)
