Cedrus pad device object

A cedrusPad object is optional. You only need to make one if you want to change a property from default.

An object of type cedrusPad provides options for a Cedrus response pad, e.g. for use by a cedrusPress element. You can have multiple cedrusPad objects in an experiment. In an experiment script you can make one outside trials with the command cedrusPadObject and add it with addToExperiment.

Input properties


No default

A string that is name of the serial port the pad is on, 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.


Default: full baud

By default the pad connection runs at 115.2k baud. If you set fullBaud = <cd>false<cd>, it reduces to 57.6k. Maybe helpful if pad connection/operation is unreliable on your system at the full rate.
