Kevin Braun / Mbed 2 deprecated DDS60-105

Programming of the DDS-60 (AD9851) frequency synthesizer from AmQRP http://midnightdesignsolutions.com/dds60/index.html I had to use long, floating math in order to get accurate frequency output.

loopsva 0:1ed24aaf786d 2 Rev Date Changes:
loopsva 0:1ed24aaf786d 3 ------------------------------------------------------------------------------------------------------------------------------------------
loopsva 0:1ed24aaf786d 4 100 5/06/11 - putting things together, first cut
loopsva 0:1ed24aaf786d 5 101 5/10/11 - removed G command from menu
loopsva 0:1ed24aaf786d 6 - added AD9851 on/off to summary
loopsva 0:1ed24aaf786d 7 102 5/11/11 - added file dds60.ini, initializes file if missing
loopsva 0:1ed24aaf786d 8 - reads dds60.ini at boot up to get frequency values
loopsva 0:1ed24aaf786d 9 - added ability to store current values in dds60.ini into local memory using new W command
loopsva 0:1ed24aaf786d 10 103 5/12/11 - tried a new fix for signal quality problem. wouldn't start above 30MHz, went back to 102 version
loopsva 0:1ed24aaf786d 11 - most commands now use a single keystroke vs waiting for a CR
loopsva 0:1ed24aaf786d 12 104 5/17/11 - removed i/o delays in ad9851.cpp. results in a 40 bit download to ad9851 in 10.4uS - was 1.24mS
loopsva 0:1ed24aaf786d 13 105 6/08/11 - added "listdir" function
loopsva 0:1ed24aaf786d 14
loopsva 0:1ed24aaf786d 15 ------------------------------------------------------------------------------------------------------------------------------------------
loopsva 0:1ed24aaf786d 16 Known issues:
loopsva 0:1ed24aaf786d 17 - Signal quality is bad between 200KHz and 30MHz
loopsva 0:1ed24aaf786d 18 102 Patch fix in AD9851.cpp, routine void AD9851::FirstAccess()
loopsva 0:1ed24aaf786d 19 105 - "listdir" function works, but "listdirSD" function doesn't
loopsva 0:1ed24aaf786d 20
