portSender

 elements

Sends data from a serial port when the element starts, then registers a trigger and ends on its own (so you don't need to set property end unless you want it to end earlier). You can set elements in the trial to start/end from trigger (element properties start/end fields trigger/triggerBy). You can also set later trials to start at fixed times from trigger (trial object property start).

Trigger value recorded in record property trigger is a row vector of bytes (integers 0–255) sent. Trigger time recorded in triggerTime is time send completed relative to trial 1 start.

If you want to set options for the port, you can use pb_prefs → "Other" tab. Or to set for only the current experiment, make an object of type port and set its properties. Typically you don't need to.

Currently portReceiver elements only work with serial ports.

For each trial you define in an experiment script, you can make one or more

Input properties

Adjustable properties

You can allow the subject to adjust the following input properties of an object of this type during the experiment using an adjuster element. If you need to make other properties adjustable, you can copy the element type using newPbType and edit it.

position
nn_eyes
rotation
opacity

portName

No default

A string that is name of the serial port, as accepted by Psychtoolbox IOPort('OpenSerialPort'). From Psychtoolbox documentation: On Windows this could be, e.g. <cds>"COM1"<cds>, <cds>"COM2"<cds>, etc.; on Mac it is a path to a BSD device file, e.g. <cds>"/dev/cu.usbserial-FT3Z95V5"<cds> for a serial-over-USB device with unique ID FT3Z95V5; on Linux e.g. <cds>"/dev/ttyS0"<cds> for the first real serial port, <cds>"/dev/ttyUSB0"<cds> for the first serial-over-USB device, etc.

Record properties

PsychBench uses record properties to record information during experiments. You can't set record properties but you can see them in experiment results using input property report.
