  • Thanks again @biomurph. I'm starting to look like a real doofus missing these details! My bad!

  • Thanks @biomurph. I see the correct RFduino header and c/cpp files now.  Not sure how I overlooked them. Just a side note, it would be very helpful if you guys put together an API/SDK programming guide. This could encompass the custom RFduino libr…

  • That reference addresses the same exception type (NullPointerException), but at a completely different portion of the code. I downloaded and implemented this "Processing Debugger" to try to identify the source of the issue: http://debug.martinleop…
    in OpenBCI GUI a Blank Screen Comment by juderb April 2015
  • That did the trick! I have a Dell Inspiron 14z with Intel HD Graphics 3000. Just needed to head to intel and get the latest driver, ran no problem. I do get an extensive list of java exceptions when I start it though. I will investigate this f…
