External triggering on Cyton 32-bit board
in Cyton
I am trying to do a P300 test so that I can try to figure out the exact delay of the trigger for my group's design project, but I'm unclear about the directions listed on the external triggering page from OpenBCI: http://docs.openbci.com/Tutorials/06-External_Trigger_Cyton_Example
I'm pretty sure we have a 3.x.x firmware since we ordered and received the board in December 2017, although I'll try to make sure by checking the version via terminal emulator (once I learn how to use that). What section of that page should we be following? EXTERNAL TRIGGERING THE HARDER WAY (FIRMWARE 1.X.X)? We have an optoisolator and will be using a computer that has a parallel port with pins that emit a voltage of 0.3 V from the P300 paradigm loaded on the computer. Do I need to be loading the sample code or do I just have to put in the pins into the digital inputs and the board will automatically switch to the correct input mode?
As I'm a novice with this, I'm also not sure what the following means: "allowing you to simply read from the analog input (sending
/2) or digital input (sending /3) with the type of a command. The default board is activated by default, but can always be achieved again by sending a /0." From what program are we supposed to send /2, /3, or /0?

Hi,
Can you please give the permission for the work:" https://docs.google.com/document/d/1rdp4mJKKu5mBQRHH0cVUDW4-uLGTncGEp0tp2nXT6yE/edit#heading=h.a8ayp95sr5wc"

@faheemersh, hi. If you right-click on your Google Drive file (external triggering guide), then select Share. You can click options that will "allow anyone with link" to access the document. Without needing to grant access to each person individually.
@wjcroft, Hi! I actually closed off that document since it was unorganized and incomplete. I tried to track down wherever I posted that link and instead placed a link to my github, which has all of that information and more: https://github.com/faheemersh/Senior_Design_Dry_EEG_BCI/wiki/Overview
How can I find my Google Drive file (external triggering guide) ?
As I mentioned, you can find this information on my github: https://github.com/faheemersh/Senior_Design_Dry_EEG_BCI/tree/Validation
