I want to do an EEG experiment with Psychopy and Brainvision software (through BrainVision Triggerbox). I know how to use Builder but I am pretty amateur in coding. Since I must use a serial port for sending triggers, I could not use the Builder. My planned experiment is to playing sounds as the stimulus and sending the time of the stimulus to the EEG recording system. For a test of sending triggers, I just created a simple version of the experiment like this:
I have found this code suggested:
import serial import time import threading Connected = True PulseWidth = 0.01 def ReadThread(port): while Connected: if port.inWaiting() > 0: print "0x%X"%ord(port.read(1)) # Open the Windows device manager, search for the "TriggerBox VirtualSerial Port (COM6)" # in "Ports /COM & LPT)" and enter the COM port number in the constructor. port = serial.Serial("COM6") # Start the read thread thread = threading.Thread(target=ReadThread, args=(port,)) thread.start() # Set the port to an initial state port.write([0x00]) time.sleep(PulseWidth) # Set Bit 0, Pin 2 of the Output(to Amp) connector port.write([0x01]) time.sleep(PulseWidth) # Reset Bit 0, Pin 2 of the Output(to Amp) connector port.write([0x00]) time.sleep(PulseWidth) # Reset the port to its default state port.write([0xFF]) time.sleep(PulseWidth) # Terminate the read thread Connected = False thread.join(1.0) # Close the serial port port.close()
But to be honest, I could not find in which section I should use it.
I would be happy if someone helps me.
