Code for Serial Event Marker via serial port

[jarrod hollis]

I am using Emotive EPOC  EEG with their testbench software  which  collects event codes sent via a COM port.  (see screenshot for  settings)

Can I send a numeric code for a visual stimulus  from Psychopy  to  the serial COM  port?    What code would I need  for this?

I am new to programming   so any help would be greatly appreciated.

Should be possible, see http://www.psychopy.org/api/serial.html

Read the full documentation on serial.Serial() here: http://pyserial.sourceforge.net/pyserial_api.html

As you can see, you can specify all the parameters in the dialogue in your screenshot. Hope this helps!

Best,

Jonas

Thanks for the links...I have tried them  but I am still struggling a bit.  I have tried  to load  the pyserial   from the link below  but this will not load on my PC  (I am using win7 64bit)    I get an error saying I dont have Python on my system.

In Psychopy  I have placed the code into a simple script at the point where the stimulus is presented.....Is this the correct thing to do?? My output is on COM7 virtual COM port, my baud rate is 9600  have I missed anything I need??

pyserial is included in the standalone distribution of psychopy - no need to install it separately.

Also, in version 1.79.01 you'll find a component for parallel port outputs in the builder (using pyserial behind the scenes).
