Hi everyone, I am new to Psychopy and have been trying to send a TTL signal. I know there is a parallel out component in the the builder. I did try to use it but my screen is closed automatically. Also, I need to send the TTL signal at the beginning of displaying the image. I am new to this, so do I need to find the address of my port? I need to send the signal through USB . Any help would be much appreciated.
Hi there - you can use the parallel class to send/receive triggers through a computer’s parallel port, but it sounds like you’re trying to send it out from a USB? Perhaps this forum post might be a good jumping point.
