Dear customer

Following this message will be the latest C3x DSK software sent in four
additional email attaches (the mail server is limited to 1.5Mbyte).  There
is no fancy install, but but the four zips are easy to manage.  Three of
the four can be copied into a root directory and expanded with the '-d'
to expand subdirs.  You can unzip into the old DSK directory, but this
will overwrite old files.

The fourth is the Win32 support DLL's for the Win32 app.  You will want
to expand this in the DSK3WIN subdir expanded from B125_WIN.ZIP.  If you
have Borland 4.51 (or later?), this step may not be needed.

The included windows application is compiled for 32 bit windows (Win32)
using Borland 4.51 C++.  It can just as easily be compiled for Win16, but
would require a different set of support DLL's.  At one time, this source
could also be compiled using MSVC++, but has not been recently verified.

The required Win32 support DLL's will work from the application directory,
so there is no need to copy them to the \WINDOWS subdirectory.  Many
applications install or blind copy these files to the \WINDOWS directory.
This is something to avoid in development software.

C:\MYDSK\pkunzip -d b125_src.zip    792881b All the source files
C:\MYDSK\pkunzip -d b125_exe.zip   1046193b Just the EXE files
C:\MYDSK\pkunzip -d b125_win.zip    279482b Combined FFT/OSC Win32 app
C:\MYDSK\DSK3WIN win32dll.zip       277005b Borland Win32 support DLL's

The win32 application is called BEAMER3.EXE.  This was initialy to be a
beamforming demo using an FFT, but was never completed.  A new name has
not yet been picked.  Check out the accuracy of Frequency  measurement.
If you hit the '5' key it will cause the AIC to loop back a self
generated a precision sine wave of Fs/10.  The FFT is also new.  This
FFT is a complex radix-2 REAL FFT that no longer needs a twiddle
lookup table.  A 1024 point FFT now fits in less memory than the
orginal 512 point FFT.  Sorry, but this and other documentation is not
yet complete.  I am currently pre-occupied with the TMS320VC33!

Be sure to read the WHATSNEW.TXT file as there are a lot of new things
since version 1.22.  For example, C source debug in DSK3D!

Best regards, Keith Larson
