I/O acces (and a lot of other things)

[mpkerkho]

Hello,

I have no programming experience, I have already learned the basics but I think I need some guides to find the right tutorials or places where to look.

I am doing in a project that involves biofeedback. we have a device for data acquisition and I have the drivers for that machine. Also is there software that displays the biodata (for example heart rate).
In the end, I want to use this data and visualize it in another program but for now, I just want to get the data out data-acquisition software and show it in another window.

To summarize: I have a program that reads the data and does some processing on it. I want to read that data out and display it in a seperate window.

Can someone please provide me some links or help on what I should learn to 'extract' the data from the other program.

And another question: is it possible to write my own program, where I only use the drivers or something? If so, how can i learn how to acces this input?

Thank you very much!

The generic term for this is ‘Interprocess Communication’. It is an advanced topic and nothing a beginner should tackle.

And another question: is it possible to write my own program, where I only use the drivers or something? If so, how can i learn how to acces this input?

Yes; however, your data acquisition software likely exposes COM interfaces or something like that; perhaps only C/C++ functions which you might have an include file for. This too can be an advanced topic.

If you’ve already sunk several months into console mode C++ programming you might want to start to learn GUI programming. Perhaps look at this link…

You havn’t really given enough details for anyone to provide you with much of an answer here. For example, “we have a device for data acquisition and I have the drivers for that machine.” What device and what drivers?

In other words, is there a manual for the data acquisition hardware which might describe how to programitically interface with it? Perhaps there is a lib and associated inc file which might allow interfacing with the device.
