Standard Standalone? (y/n) Yes
What are you trying to achieve?:
Hi guys, it might be a board question but I am so struggling with to integrate Tobii spectrum with Psychopy. The software I am using to record is Tobii Pro Lab. I am a completely new beginner in terms of coding and eye tracking. Is there anyone who’s willing to share how they integrate Tobii with psychopy? Thanks in advance.

I triedTitta, but I got error message like this:

Hi! A late answer: You need to change the sampling frequency in the script breakout_tobii.py.
settings.SAMPLING_RATE = 300

You’re trying to use a frequency of 600 Hz, but only 300, 150, 120, and 60 Hz are supported by your Spectrum.
