Hi @pushtheworld, I could make it work. It is not because of the processing program. It's because of the old version of the library LSLLink. I did find the newer one and updated it and it works. Thanks.

Hi @atom2626, I really would like to try your Matlab source code. However, the sourceforge link you provided is unavailable now. Could you share the code with me? Thanks, Anh

Hi @Gabelbagon, I am having the same as Katherine did now. I can be successful to open a LSL stream from OpenBCI_GUI using the Networking widget and receive the data in the terminal by running the python script ReceiveData.py. However, I canno…

Hi Everyone, I was successful to stream data using LSL protocol and receive it in the terminal using a python script. However, I still cannot receive the data in Matlab. The function inlet.pullsample() always return an empty vector [ ]. Could …

I am using Macbook Pro installed macOS Sierra. I would like to say that I could be successful to stream data now. I tried to download the LSLlink folder and paste it again into my library. As a result, the GUI did not freeze anymore and I can achi…

This is the screenshot of the preferences. https://drive.google.com/open?id=0B-t12XNu78ajNDJnaG1FT2VFbkk Could you point me to the place where I can download the latest lsllink folder? I am using the one downloaded from https://github.com/Ope…

Hi @pushtheworld, As running from Processing, it seems that I have a problem with the location of placing the file liblsl64.dylib. The screenshot of the error generated by Processing when I tried to start LSL streaming protocol is in the following…

It does not work in my case of Cyton board. I have left my problem in the discussion referred by wjcroft already. Hi @compmonks, which board are you using?

Hi Everyone, I have the same problem that the OpenBCI_GUI freezes when I try to stream with LSL protocol. It worked well in case of OSC and UDP protocols. I have a Cyton board and run the OpenBCI GUI on macOS Sierra. I read the thread but the …

Hi @mark.o.s, I think you could stream and parse the EEG directly in Matlab with the Cyton board without the use of LSL. Is it right? If yes, could you share with me how you did it? I am struggling to read the EEG from my Cyton board to Matlab. I…

Hi compmonks, I have the same problem when trying to use LSL protocol to read data from the board. Have you solved it?
-
Hi @wjcroft, I have nearly the same problem. At the beginning of running the board (of 8 channels only), all channels are railing. Could you explain what railing value means? I feel fatigue about its meaning.

I want to upload the firmware (with using SD card only) provided in Github (https://github.com/OpenBCI/OpenBCI_32-write-to-DS-only). I followed the instructions wrote in the website (http://docs.openbci.com/tutorials/02-Upload_Code_to_OpenBCI_Boar…

@yj Thanks so much, Yannick, for your promising conclusion I am excited to upload your firmware to my board, that I hope I will receive soon!

Hi Yannick @yj, Based on your calculation, I understand that "8 times faster and shorter @ 2kHz" is related to the speed of having available data but not the speed of writing the data from the Board to the SD card. Please correct me if I still mis…
-
Hi @hitheshaum, Thank you for your sharing of the code. As my understanding, doing interrupts helps reduce the time of getting the new data on the board. Would it help increase the speed of writing the data to the SD card when increasing the s…
-
Hi Yannick @yj, Does you mean that ... it always takes approximately 5 minutes to write 11.000 blocks without any concern on the sampling rate of @250Hz or @2kHz? How is a "BLOCK" defined here? Thanks.
-
Hi Yannick @yj, 1. The files were from the SD card (in form of hex value) 3. When mentioning the sampling rate, I actually concern on the writing speed because it has very slow writing speed (need approximately 1 minutes to write some seconds …
-
Hi Yannick @yj, I am working on increasing the sampling rate of the board as well as writing the data to the SD card only to speed up its current writing speed. So that I am interested in your work in this discussion. Could I ask you if the mo…

Thank you very much for your help since our research project needs to be reported in December and we cannot have the signal without your board.

I did re-install the driver. But still, the Dongle blue LED didn't light up when I plugged it in before and after re-installing the driver.
-
My order number is 1650 (Po #: 650 shipped on 09/30/2015). I haven't re-programmed the Dongle yet. In my opinion, there was something wrong with the Dongle because the PC cannot detect the Dongle anymore. I tried with different PCs as well as diff…

I simply changed the board firmware to test it by not writing the acceleration in the packet sent to the PC (OBCI.useAccel = false). That's all what I did. It still worked well for a while after that change.
