[hpsdr] Looking for guidance

Hi Berndt,

All schematics and pcb files are available in the public downloads
directory at http://openhpsdr.com.  Select the card name in the "Filter
by folder" choice box to find them easily. Currently Metis is not there
but I expect they will made available when the card is in production.

The source code for all the Verilog FPGA firmware is in the svn.

Mercury and Penelope can operate full duplex and on different
frequencies.

The data between the hardware and PC is defined in the document
"USB protocol V1.27.doc" in the svn at
svn://64.245.179.219/svn/repos_sdr_hpsdr/trunk/Documentation.  The basic
data from the hardware to the PC is status information, I/Q samples from
Mercury and microphone samples Penelope.  The data from the PC to the
hardware is basically I/Q data to Penelope, audio data to Mercury and
control information.

Metis currently is simply a replacement for Ozy/Magister.  The data
rates for the I/Q data is really too high to stream across the internet.
A single receiver running at 192000 samples/second requires 9Mb.  It
does work across a local lan with no problems. For remote operation I
have developed a client/server architecture that can run over the
internet using either Metis or Ozy/Magister.  All the source code is in
the svn store under
svn://64.245.179.219/svn/repos_sdr_hpsdr/trunk/N6LYT.  I am currently
looking at putting a soft core processor on Metis so that we can write
more complex server code for it in C rather than try to write all the
network stack in Verilog.

Regards,

John g0orx/n6lyt
