Restart PsychoPy (save your experiment first!) Place a copy of all of these in the same folder as your PsychoPy experiment file (the one with the. In the unzipped folder, find and copy the files “inpout圆4.dll” and “inpout圆4.lib” from the 圆4 folder, and then the file “inpout32.h” from the Win32 folder. This will be called something like “InpOutBinaries_1501.zip”. The correct folder to select is shown here. You need to use the “Binaries only - x86 & 圆4 DLLs and libs” option under the Download Links subheading near the bottom of the page: We’re going to pre-empt that error by downloading and installing the correct drivers now.ĭownload the InpOut圆4.dll and InpOutx32.dll files from here. For Windows users, a common error when trying to communicate via a Parallel Port component is that certain drivers are not found. ![]() If you’re using a Mac, it’s recommended that you skip this step. Step two: Make sure you have the correct drivers installed ¶ The correct port address will now appear in the drop down menu in the Hardware tab of the Parallel Port component. So if your port address appears in Device Manager as “0378-037F” for example, in PsychoPy this would be written as “0x0378”. ![]() We tell PsychoPy to read it as such by prefixing with “0x”. The parallel port address is usually a hexadecimal address. Now we set that condition by inserting the following code: In the Basic tab, we’ll choose to start our trigger when a condition is met by selecting condition from the Start drop down. Also, this doesn’t help us if we want to send our trigger to indicate something with variable timing, such as when a response is made.įor maximum precision, we’ll set the trigger to be sent when the status of our stimulus is set to started: But this is not the most precise way to do this. We could do this by simply setting the onset time of the trigger to match that of our stimulus. Now, imagine we want our trigger sent to indicate stimulus onset. Select the Parallel Port component from the I/O or EEG component drop-down menus. If you’d like to use a Parallel Port to record responses (for example from a button box) please read this excellent thread from our Discourse Forum user jtseng.Īdd your Parallel Port component to your routine in the same way that you would with any other component: This component supports both traditional parallel ports and USB devices. This can be found in the I/O component drop down. PsychoPy has a Parallel Port component in Builder view. Although these guides will talk you through how to communicate with EEG hardware, they can really be used to communicate with any device that is connected via the same method:Ĭommunicating with Emotiv please also see this video tutorial.Ĭommunicating via a Parallel Port ¶ Step one: Set up your Parallel Port component in Builder ¶ Communicating with EEG ¶īefore getting started with an EEG study in PsychoPy, we highly recommend reading relevant information on how to measure and understand Timing Issues and synchronisation. The page is being updated regularly so if you don’t see your device listed here please do post in the forum as we keep an eye on commonly-faced issues (and solutions!) there. This page provides step-by-step instructions on how to communicate with some of the more commonly used hardware. PsychoPy is able to communicate with a range of external hardware, like EEG recording devices and eye trackers.
