Re: ActiView: LabView Resource not found

Experiencing exactly the same thing outlined by the original poster in this thread. The computer is running Win 10 Home edition, but it is relatively new and capable. The DLLS are in the folder with the ActiView software. I have downloaded from the website and I have used the version on the flash dr...

Re: Developing ActiView with LabView 2010 for mac

Hey PMAC - I am trying to get ActiView running on an iMAC with OS X 10.11 El Capitan and the software and runtime engine seem fine, but the USB device is not found. When I run sync test, it stops immediately as says it cannot find the Labview DLL and/or USB device: "Last login: Thu Oct 27 14:51:53 o...

Interfacing with the ActiveTwo digital IO port via C++

I have engaged a software developer to develop a piece of code to set events directly on the ActiveTwo digital output port via the C++ developer kit and USB driver. He is not an experienced C++ developer and is having some problems with getting the initialization to work. To my understanding, his co...

Re: 2-laptop setup, parallel port problem

I spent quite some time today digging into how to get parallel event output from Presentation via StimTracker's USB virtual serial port, but I was unsuccessful. The NeuroBS Wiki at http://www.neurobs.com/wiki/Presentation/Hardware/Other_Devices/Cedrus_StimTracker indicates support for the initializa...

Re: 2-laptop setup, parallel port problem

StimTracker is nice when you need photocell or audio trigger sensing. This may be useful for timing testing purposes or because you have no other way to associate trigger port output with a visual or auditory stimuli because you are not using a purpose built experimental control program like Present...

Re: Open source MATLAB API

A client asked today about using the API on 64-bit Windows 7. I assume that others have been doing so successfully. Anyone want to comment on successes or challenges using the API under Win 7 64?

Re: Open source MATLAB API

A, I don't know how much effort would be required to run it on Linux, but I suspect it will not be too bad. The ActiveTwo drivers for Windows and Linux were developed by the same person, so they should work as similarly as possible. MATLAB code should be relatively transparent too, I think. But then...

Don't have ActiveTwo hardware and want to use simulator

It should be possible to run the API with only the simulator, no hardware or driver, though it may be necessary to modify the code to do this. Anyone tried this yet?

Support for the API

Hi, all. I'm not sure if everyone understands the fundamentals here, so I feel the need to provide some background. The API has been moved into the open source domain under a FreeBSD license. The upside for you is that we are giving away the source code; the downside is that we are not supporting it...

Hi all. Over the course of 2010 and 2011 Cortech Solutions employed a developer who created a MATLAB API for the ActiveTwo system.
