# psychopy.serial - functions for interacting with the serial port¶

PsychoPy is compatible with Chris Liechti’s pyserial package. You can use it like this:

import serial
ser = serial.Serial(0, 19200, timeout=1)  # open first serial port
#ser = serial.Serial('/dev/ttyS1', 19200, timeout=1)#or something like this for Mac/Linux machines
ser.write('someCommand')
line = ser.readline()   # read a '\n' terminated line
ser.close()


Ports are fully configurable with all the options you would expect of RS232 communications. See http://pyserial.sourceforge.net for further details and documentation.

pyserial is packaged in the Standalone (Windows and Mac distributions), for manual installations you should install this yourself.
