Some things can be handled with scilab + xcos http://www.scilab.org/products/xcos
http://spoken-tutorial.org/wiki/index.php/DAQ If you do not need RT signal analysis, consider spitting data acquisition and data analysis. Most loggers today have large memory or at least async data communication backed by a memory buffer. This simplifies setup and reduces costs, but does not give you RT and is not good for time critical applications. If you need RT signal processing and control you may find useful XCOS (above), SCICOS http://www.scicos.org/ or recently with OpenRTDynamics http://openrtdynamics.sourceforge.net/bigace/ and the beagleboard ( http://beagleboard.org). Of course much reading and trials compared to a commercial solutions. mic Possibly the software problem is more interesting - I'm surprised there > isn't an open source LabView clone effort given all the universities that > could benefit.
