The
BioSemi acquisition software (ActiView) is both delivered as an
executable and as an LabVIEW library complete with source codes.
The easiest way to add real-time modules is to work within the LabVIEW
language. Our software is completely open, and the LabVIEW language
is quickly learned. However, it is also possible to call Matlab
script from the LabVIEW code. In this
last case, you would use our basic acquisition code as a shell for
your (existing) MatLab applications. However, if the real-time applications
are relatively simple we would advise to reprogram in LabVIEW.
All
your off-line work can of course remain fully based on Matlab. You
will just have to add a read-in part for our BDF file format. Examples
how to do this with Matlab are downloadable from: http://www.biosemi.com/download.htm
The combination LabVIEW_acquisition --> BDF file --> Matlab_analysis
is used by many of our customers, and seems to combine the best
of both worlds.
It is of course possible to built your own complete new acquisition
program in Matlab, but this is a lot of work. Our LabVIEW program
works very stable, and it has proved to be very easily adaptable
to new research applications. If you have LabVIEW 7 available, you
can already play with the source code after downloading the acquisition
program from our download page: http://www.biosemi.com/download
The basics of the LabVIEW language are quickly learned. Also, National
Instruments offers a free
evaluation version of LabVIEW
You can download the latest version of our standard acquisition
program ActiView from: http://www.biosemi.com/download/LatestActiView
We deliver the source code of ActiView as a LabVIEW library (*.llb).
This library contains all the source code. You can not run the program
with traces on the display (data acquisition running) without hardware,
but looking at the code will give you an idea of the setup and possibilities/complications.

code can be downloaded from http://www.ni.com/pdf/manuals/370109b.pdf
