Hi,
I got my PIC producing 10mb data/hr,
now I need something to receive the data
via bluetooth store it and do some statistical analysis
on it and display the results etc.

Before I reinstall my old copy of MSVC C++ I wondered
if anyone knows of a quicker way to get results.
it will probably take me a while to do it with C++ doing all the coms
and windows and maths and graph stuff with mfc,
but ive looked at a few suggestions made like scilab but it doesnt seem
to be all the flexible,
maybe would be realy good to display the final results in 4d or
whatever.

there are also some realy hi price packages too,
It might take me longer to wade through all the different ones
then learn it, then find out its not actually so easy to do exactly
what I want after all becuase its not flexible enough.

maybe I need a good C++ library wich maybe even replaces MFC ?

Does anyone have any usefull experience to share ?

basically I have an experiment wich measures the signal rotating at 3rps
and I need to determine direction from this wich will vary cyclicly
over 24hours.

The signal is 1000 times lower than the noise however,
also considerable number of points will be lost due to glitches etc.
The PIC already does some DSP to recover the signal up to this low
level.

or maybe is there another forum wich might specialise in this stuff ?

C# has (in the latest release) good serial suppurt, which shouldnt have a
problem linking to serial over bluetooth, and there are a number of
decent and FREE 3D graphics interfaces for C# -- DirectX and OpenGL at
the low level, Axiom and others at a higher level (though those are more
scene oriented)... in any case... C# eliminates the majority of the crap
that MFC or any C++ UI will put you through creating a decent UI

We can take this off group if you'd like to discuss it more.

thanks, ive not looked at C# yet maybe its time to,
is it similar enough to c++ to pick up quickly ?

Il go look for some online c# references.

its not that far off topic here is it? it is data from an electronic
experiment.
maybe if we get involved in how to combine al the differnt windows
attributes such as scroll copy/paste in one window ..

C# is a blend of C++ and Java -- you wont have any problems picking it up
very quickly -- plenty of example code out there --
http://www.codeproject.com is a good place to start

If you dont want to get hooked in to the MS world -- use Java -- Java3D can
handle the data display and the netbeans IDE is pretty comprehensive (you
can download it at java.sun.com free)
