Hi,

Anyone know how to interface biopac with matlab to obtain values
in realtime. Most of the info on google shows only how this can be
done offline from saved files *.acq using the supplied software
AcqKnowledge.

thanks

Biopac is it's own real time environment, which provides some analysis
tools. I suppose you can throw out the whole software package and just use
Matlab to get at the hardware, but if that were the approach I was taking,
I wouldn't start with the Biopac hardware--I'd go with something I could
get drivers for.

Hi,

I have been trying various approaches to my problem including
trying to write a hardware driver....its taking very long time...

Do u know if i can connect the biopac signals to a Ni 6024E DAQ
to get realtime signals...

thanks for ur help

To some extent. You can sample from their transducers, but as the biopac
unit provides power and/or excitation to the transducer, it must remain
plugged into the biopac and you can sample in parallel. You will need to
get the pin outs from the biopac people.

For small signals, like biopotentials, I suspect it won't be possible
because I don't think you will be able to find the post-amplified signals.
You would need to make/purchase your own biopotential amplifier as a front
end to the 6024E board.

Hi,

I have searched how to take out online data from BIOPAC to MatLab.
And I found here.
Dr.Britto, have you eventually found a way?

Thanks for your help.

Hello,

I am wondering about the same problem. Has anyone found solutions to interface BIOPAC with MATLAB in real-time?

Thank you,
Becky
