You'll have to check the firmware code, this feature is only intended for the firmware developers, not end users. I believe that once you have switched the Cyton mainboard to use the 'debug mode', it may then abandon sending on the normal pathway. P…
-
The packet format, end codes, etc., that you see in debug mode, may differ from what is documented. Because in the normal case the packets are buffered by the RFduino's and they do some massaging of the packet format. But another question that se…

I'm not clear that using that data stream is going to allow you to talk to the board via Brainflow. At a minimum, you would need to change the Brainflow 'device' code. I also believe there may be added bytes that the onboard or dongle RFduino interc…

Correct. But is 'debug mode' what you are looking for? You would still need to make substantial firmware changes.

Hi @shaluska, I may have created some confusion by pointing to the 'standard' link for loading the GUI in Processing: https://docs.openbci.com/Software/OpenBCISoftware/GUIDocs/#running-the-openbci-gui-from-the-processing-ide That 'standard'…

Hello Day, I believe your proposed project would be a valuable open source contribution, so please continue. I suggest you turn your post above into a pdf and post it (along with some introductory comments) on the NeuroTechX Slack, where many mor…

Mentioning Richard @retiutut, who is an expert on Max / PD. And the developer for the GUI.

@smanne said: Thank you for the detailed advice! I really appreciate it William. I require for this project to be bare-metal, and BrainFlow requires an OS to run, so I'm trying to find a way around it. I see these possibilities: I'm u…

@smanne said: ... Thanks for the response. Does this mean I cannot directly communicate with the Cyton over UART, and instead have to communicate over the Brainflow library? Correct. The UART ports you see on the dongle are NOT availab…
-
Hi SManne, Have you considered using a Raspberry Pi, such as models 4 or 5, which have USB host ports that the dongle can plug into? The Brainflow library is designed to interface via the dongle. https://brainflow.readthedocs.io/en/stable/Supp…

If you checked some of the 'Community' page links I gave two days ago, and the page 'layout' seemed wonky. Check again, the Wordpress bugs have been fixed. Regards,

Hi, The BCI 'paradigm' you refer to: smoothly moving a mouse cursor via signal processing of scalp detected EEG, is generally considered difficult, if not impossible. HOWEVER, it would be possible to have a monitor display presented to your subje…
-
Have you experienced 'shifts in consciousness' or perception, following such neurofeedback? What have been the results so far? So you are up-training coherence? Sometimes brain maps show 'too much' coherence, and training should be in the opposite d…

Sorry for my confusion regarding your app language. When you said 'browser-app' I assumed you were using javascript or typescript. I now see your app is entirely Python based, so obviously those are the examples you want to view.
-
I took a very brief look at your paper. I see the correlations you are trying to make. Can you summarize what practical applications might result from your research? For example in neurofeedback, BCI, EEG medical diagnosis, implications regarding mo…

Hi Michael, Have you looked at the Brainflow / Typescript example codes? https://brainflow.readthedocs.io/en/stable/Examples.html#typescript-get-data-from-a-board I notice all those are using the simulated 'synthetic' board type. But it is …

On the TI ADS1299, SRB2 is a 'bus' (common connection) for all the positive pins, IN1P IN2P IN3P IN4P IN5P IN6P IN7P IN8P. https://openbci.com/forum/index.php?p=/discussion/2095/srb-and-references Thus connecting the scalp electrodes to the ne…

I suggest sending an email to Customer Support: (contact at openbci.com) and include a link to this thread. It seems possible that the build instructions no longer work with the referenced libs.
-
The '(Fall 2016)' post was made in that time frame. So that explains the old IDE version reference.
-
Are you following the build instructions? The build doc asks for Arduino IDE v1.8.19. https://docs.openbci.com/Cyton/CytonRadios/ https://github.com/OpenBCI/OpenBCI_Radios There are some other references to the custom GZLL protocol (supplied …

Apologies, I forgot to mention the GUI Marker widget. I was unclear from your initial post if you were using the GUI. You mentioned both the LSL LabRecorder and Brainflow. The fewer software / hardware components involved, the less the latency. You …

@cgontier said: ... Sorry for the naive question, but can I do it without LSL, i.e. can triggers from an external software be directly sent to the Cyton board (for instance via the USB dongle)? The Cyton dongle or mainboard cannot receive…

This Forum is good for networking and finding inspiration from other related projects. But for actual hardware or software failures you are seeing (even when following directions), then getting expert advise from the engineers at customer support wi…

The Cyton external trigger pins are intended to be used with a source of DIGITAL input levels. https://docs.openbci.com/Cyton/CytonExternal/#adding-trigger-markers-from-external-sources In the diagram there, the 'External Trigger' 'Signal' and…

One consideration to note with the dongle. If the table or surfaces near the dongle are METALLIC, then this can attenuate and distort the transmitted / received radio signals. This is why the usb extension can help. If you use the extension to posit…

Have you emailed to customer support? Send to (contact at openbci.com). This will create a ticket so the engineers can take a look. Has your Cyton board EVER worked correctly? If not, it is possible your mainboard or dongle is defective.
