I seem to remember seeing a Origin project tutorial from an earlier version that mimic-ed data aquistion from an instrument directly into Origin. I also have used an ultra-centrifuge that was controlled directly from Origin. I have an instument (Nitric oxide electrode from WPI) that I would like to port directly into Origin, skipping the intermediate data aquisition software so there is no cut and paste. (I already have the A/D converter and can collect data thorough another program) Is this possible? Given the above evidence it is most likely possible, but I would also like to know how involved this would be. You can guess from my questions that I have only a little programming experience.
While it's possible to do this - as demonstrated by the ultra-centrifuge manufacturer(?) - it does require considerable programming experience. The Origin Professional package comes with a Library file for accessing Origin functions from another application and some sample projects written in C and Visual Basic that demonstrate creating DLLs (in C) that access Origin datasets and functions that can be used with Origin's Non-Linear Fitter. There are also applications (in C and Visual Basic) that demonstrate using Origin as a DDE Server, in which data is sent to Origin and plotted in real time (at typically slow DDE rates). So, yes, it's possible, and yes, it's involved. P.S. Maybe the tutorial you saw was UIM.OPJ in the Origin Samples folder that demonstrates using UIM Tools to mimic a strip chart recorder? This doesn't really do any inter-process communications and only demonstrates how a manufacturer might create an interface within Origin that they can use with their custom software.
