[hpsdr] Merury v 2.5 code now available

[Bill Tracey]

(Bill posting for Phil)

All,

We have updated Mercury to V2.5  Use the same procedure as before to 
load the new code into the flash memory on the Mercury board.

New features include:

1. A data stream to End Point 4 in the USB that sends a 4096 x 16 
bit  frame of raw ADC samples.  This will allow the PC programmers to 
add a bandscope, sampling oscilloscope etc,  with up to 55MHz 
bandwidth.  For those programmers working on this, the start flag is 
no longer provided, just read a 4k block of data from EP4 and process it.

2. Again for the PC programmers, the sync sequence (0x7F7F7F) now 
always starts at the beginning of a 512 byte USB frame. No need to 
hunt through the frame to find where it starts.

3. Serial numbers of the code in Ozy, Penny and Mercury are read and 
displayed on PowerSDR>SetUp>General>HPSDR>Firmware 
Versions.  Currently Penny will show 0 and Mercury 25 (for 2.5). This 
will be used by the automatic code update process when we implement it.

Many changes and improvements to Ozy and FX2 code to support the 
above, thanks to Kirk KD7IRS and Bill KD5TFD for their contributions.

I've updated the USB protocol document in \trunk\Documentation to 
reflect the latest changes.

To use the above features you will need to latest PowerSDR code etc from:

svn://206.216.146.154/svn/repos_sdr_windows/PowerSDR/branches/kd5tfd/PennyMerge/bin/Release

Please provide feedback etc to the forum.
