Sending triggers to Nexus Trigger Interface via serial port
I'm Laura and I'm working on building an experiment that records heart rate variability and changes in skin conductance while certain sounds are presented. For that, I'm trying to use a Mind Media NeXus Trigger Interface. But it doesn't seem to work. I'm new to OpenSesame and uncertain about what I'm doing wrong and even what exactly the errors mean, that appear.
and in the trial
My loop table looks like this
And I keep getting the error messages:
- exception message: an integer is required (got type Serial)
TypeError: unicode strings are not supported, please encode to bytes: 'M'
Can somebody help me? Any help is appreciated!
Thank you in advance and best regards!
