OS: Win 10
PsychoPy version: 2022.2.4
Standard Standalone? (y/n): Y
What are you trying to achieve?: I am trying to send triggers to ActiView (Biosemi) using the beta serial port component in the builder. My hardware setup is exactly as the one shown here: Serial Port EEGbiosemi
What did you try to make it work?:
I followed the instructions on this page: Sending triggers via a Serial Port — PsychoPy v2022.2.4
I created a test experiment to check if the digital signal is being sent from the stimulus presentation laptop to the EEG recording laptop.
What specifically went wrong when you tried that?:
The first error I received was:
ValueError: Not a valid parity: None
I fixed this temporarily by choosing “Off” instead of “None” in the drop down selection:
Then my test experiment run ok, no errors, the serial port COM3 was opened successfully I believe because otherwise, I would get an error.
No signal was received on the EEG laptop. I tried connecting the Biosemi USB Trigger Interface to different USB sockets as well to check whether it would make a difference but it did not.
I noticed a number of warnings in the terminal output:
2142.7694 WARNING Parameter baudrate has unrecognised inputType "int" 2142.7730 WARNING Parameter bytesize has unrecognised inputType "int" 2142.7760 WARNING Parameter stopbits has unrecognised inputType "int" 2399.9703 WARNING Parameter baudrate has unrecognised inputType "int" 2399.9731 WARNING Parameter bytesize has unrecognised inputType "int" 2399.9763 WARNING Parameter stopbits has unrecognised inputType "int"
Any hints on how to fix this?
