Where can I find documentation on the features of OpenBCI_GUI?

Hi, 

I'm sure I'm missing something right under my nose, but I've been looking for over a week for any documentation of the features and settings inside the GUI, and everything seems to stop after the installation is done. Specifically, I need to know what the output format is for the feed exports in OSC, serial, etc. for each data type.

I also haven't found anything explaining what the time plot is representing. I am a total beginner here, but I think I understand that it must be a monopolar plot, but I'm curious about this and wonder if this is the only plot the GUI can do? 

Even the most simple feature description would give me more than I know by guessing. Can anyone point me in the right direction? I have read everything on the docs site, and I feel like I've read half the forum at this point. 

Thank you...
Ali

    Anyone? 
    Is there really no documentation other than the setup tutorials? 

    Thank you.

    I have the same question.
    Can anyone please comment, even if saying "no, that's all the documentation there is" or "I've looked pretty hard too, and that's all I can find too".

    Not to de-rail from Ali's questions, but:
    (I'm strong in hardware, wimpy in software/firmware)
    In my case, by looking at the SPI SCK signal with a scope, I'm pretty sure the Ganglion default sample rate is 200 samples per second.
    I'm hoping that without writing firmware, and just with Bluetooth, I can use the GUI to change it to something somewhat faster.
    And I don't need all 4 channels, though I'm OK if I can't reduce the number of channels.
    If I knew GUI features, I may want to take advantages of those too.
    For example, I wonder whether the period of the SCK clock can be increased.

    In case it can't be done with the GUI:  if firmware has been written to accomplish higher sample rate, a pointer to it might help me enough.

    Thanks.

    Bruce, hi.

    The Ganglion is sample rate limited by the Bluetooth Low Energy radio bandwidth (at 200 Hz). It's already heavily compressed, but you could experiment with (as you say) only using 1 or 2 channels by changing the firmware. I have heard that AJ's Wifi Shield will work with both Ganglion and Cyton, so that might be the easiest way to get higher sample rates. See the Category in the right column for Wifi Shield.

    Ali,

    You are correct, the only documentation is on the Docs site,


    But the individual source code repositories do sometimes have additional documentation files,


    Regarding your plea for specific documentation on the GUI Widget output formats, please log an issue here,


    Regards,

    William
