Hello, i’m quite new in Matlab/PTB. I need to send some triggers to the parallel port for EEG data. Most people in my lab use io64 function like this : ioObj = io64; status = io64(ioObj); address = hex2dec(‘E010’); io64(ioObj,address,value); The EEG platform is on Windows 10. I develop my code …

For Linux the solutions are different, please read the FAQ: [image] FAQ Psychophysics Toolbox Version 3 (PTB-3) is a free set of Matlab and GNU Octave functions for vision and neuroscience research. - Psychtoolbox-3/Psychtoolbox-3 For Linux I think this is t…

Hello Ian-Max-Andolina, thank you very much for your quick and well documented answer ! I understand that sending messages through the parallel port is handled differently between Windows and Linux. I will then focus on Windows since it is the system on which the “official” run will be performed. …

Ok just a quick answer to myself : I used web.archive.org to see if (by chance) a snapshot of this page of usd.edu has been done in the past. You can access a snapshot done 2 years ago (in 2021) at the following address : Mex-File Utility for Fast MATLAB Port I/O (64-bit) I will check that (and c…

[image] DonutMan: s this is an expected behaviour since I have not parallel port or perhap this is a Windows only function… Yes, web.archive.org seems to be a snapshot of Frank Schieber’s web site. Frank meanwhile retired and his webpage is down. I still use io64 on Win10 and Win11 PCs withou…

Hello Andreas, thanks for your reply ! What do you mean by “run the InstallDriver.exe” ? Is InstallDriver.exe some sort of Windows executable available by default with Win10/11 ? Because I don’t find any InstallDriver.exe on the USD webpage… Thanks a lot for your information :slight_smile: BR P…

What do you mean by “run the InstallDriver.exe” ? Is InstallDriver.exe some sort of Windows executable available by default with Win10/11 ? It came with the binaries of the io64, I can send you a zip file. But maybe placing the inpoutx64.dll in the System32 folder is sufficient. Give it a try. B…

This last should do it. As an aside, running in Linux will make a lot of things easier and more reliable. The parallel port is only one - but see the note from Ian-Max-Andolina; USB offers more flexibility (having said that, we use a parallel port on Linux)
