Repeated serial out

PsychoPy version (e.g. 2024.2.4 Py 3.8): 2025.2.0

I want to send a signal with a serial out to Biopac for two types of situation :

  • To signal the start and the end of a stimuli (video) –> I succed, wich means all my devices are working
  • To signal each time a participant click on ‘h’. I think it isn’t possible with builder only to send many triggers with the same serial out. But I didn’t find how to code ?

Does someone already had to do something similar ? The notice on psychopy are different from the 2025.2.0 version… Thank you so much for your help
