Raspberry pi 4?

Hi all,

I am planning on interfacing RPi4 with PsychoPy to use them for psychophysics experiments. I’d need good timing with the RPi4 and PsychoPy and am planning on testing the screen trigger using the photodiode and comparing it with the TTL signal.

Does anyone have any insight/experience with using PsychoPy with raspberry pi devices? I saw that Raspberry pi was usable with psychopy but was not sure if the timing has ever been tested.
