Logging parallel port triggers

Builder
1

Hi all,

I’ve been creating my experiment mostly using builder mode. However, I’d like to be able to save the timings of my parallel port triggers in the log file. Is there a piece of code that I can add in order to do that?

Best wishes,
Ashley

I hadn’t actually thought about the fact that parallel port functions aren’t currently auto-logged. We should change that.

You can add arbitrary messages to the log files using the logging module:

But also, if your trigger is tied to the frame flip (e.g. because it tags the onset of a visual stimulus) then you’d be better to use the win.logOnFlip() and the trigger should be sent using win.callOnFlip():

That’s great. Thank you!

Auto-logging triggers would be very useful though, good idea.

In the end what is the code that you used? It would be super useful to know :grinning:
