  • Hello William. You can close this thread. I have everything working fine now. The only remaining question is if someone remembers what is the difference between the raw serial output on Serial0 of thr Cyton and the actual data received by the UA…
  • Dear William. I have new PIC32 running with the defaultBoard.ino sketch compiled and uploaded using Arduino IDE. I have the correct message at the UART and respnses to commands like // or ?. However, I do not have the Accelerometer circuit install…
  • Thank you William I did install the BrainFlow on my Rasperry 4 successfuly. Tomorrow I will try some examples. Will keep you updated. Have a great afternoon. Nelson
  • AH. Understood. It is fine for me. BTW, I runned a very basic test at the Hospital last Friday. We took an EEG on a patient using bipolar montage 5 electrodes each hemisphere. I finally used my WiFi shield version and the OpenBCI_GUI V.5 running on …
  • Hi William: Is there any reason a BDF File can not be played back ? I get the message Playback does not contain the desired header data. Recorded using OpenBCI_GUI 5.0 I was able to read the file with EDFbrowser without any conversion. So I assum…
  • OK. I understand now. I need to do more testings. This was just a go/no-go primary testings. Again, my WiFi shield with a nodeMCU versio 0.9 is as reliable as a poor quality chinesse of the shelves piece of junk. So, I do not give a dime for it... I…
  • Yes, I did it. But GUI 4.2 scanner function showed the SSID of my WiFi shield and I did not care about the IP address. GUI 5.0 does not show the WiFi SSID but knowing the WiFi address I was able to connect without any problem. This is the only diffe…
  • OK. Direct mode with WiFi shield default IP 192.168.4.1 works (so far). I need to review why commands from Hardware Setting screen takes so long to execute. Also I have to explore why the stream coming from the WiFi is a little bit "jumpy". Like it …
  • Will test it and let you know. I will use the WiFi shield in the mode of AP, connect my Windows directly to the NodeMCU and try Richard's suggestion.
  • Cyton-Original form openBCI. Rfduino dongle-Original from openBCI. WiFi-NodeMCU ver 0.9 flashhed with openBCI firmware. All the stuff runs OK with OpenBCI_GUI 4.20. I also have a GUI (4.20) version with LSL support for receiving the stream, Cyton c…
  • William: I removed my WiFi connection, restarted everything and ver. 5.0 is up and running ha´ppy with the RFduino dongle. First impression is that the overall performance is notably better than ver 4.20. So.... CONGRATULATIONS ! Once WiFi become…
  • I am also testing with a 5 volt 20.000 mAh battery pack (used for cell phones). This provides a fantastic regulation and very long time of continuous use. Will see...
  • The testing with the Cyton and the WiFi shield are still going ON! It worked fine, and yes, I used separate set of batteries and I am using the Ultimate Lithium batteries for the 6V pack and a separate set for the WiFi nodeMCU. Will keep testing ! T…
  • Great! Unfortunately I do not have a Ganglion board with me. But there are some other issues involved in my investigation. Number of channels, sampling speed (overriding the USB RFDuino dongle), and other considerations makes the Ganglion+WiFi shiel…
  • Dear William: I am testing and experimenting different options. So far, WiFi Shield works but it is quite erratic. The hardware involved, ESP8266 is sensible to its manufacturing origin. Some of them works better, some of them are horrible. In sum…
  • Dear William. There are several aspects that makes this idea interesting to be explored. I can have my computer running OpenBCI_GUI connected to my home AP as well as the Raspberry in a different place, not limited by the BLE range. Other interes…
  • Hi Max. I've found no better answers than experimentation. I did make the NodeMCU work as a WiFi shield for the CYTON board, and the final results shows: 1) it works as expected. 2) the stability in terms of data transfer between the CYTON and Node…
  • Dear All. Thanks a lot. The information provided is highly valuable! Will post my results once ready.
  • Glad to hear that! Unfortunately I was not able to port the firmware to the chipKit u32 yet. The problem is I can not manage to use the DAISY board as main ADC via SPI. I have added the DRDY pin from the ADS chip to the chipKit and feeded the DAIS…
  • Dear William. My question could be b etter understood with an example. Suppose I have the normal setup. CYTON+Dongle+GUI using RFduino BLE. I would like to add a second communication channel (lets say Serial1) connected to a different PC and use t…
  • I apologize for my lack of professionalism. Due to the annoying circumstances (covid-19) i am working alone at home and the challenge of having a CYTON under test for further approval in a real Hospital, requieres a great effort. I can not manage…
  • Hello ! Still fighting.. What exactly means the RAILED message ? Why I see (randomly) channels going to RAILED while no signal is applied? Does the GUI reads the default settings from the CYTON ? Thanks
  • Hello. I modified the W_TimeSeries.pde as per your instructions. I need to write "Fp1-F3" Text, and so on. How do I increase the WIDTH of the Button Cell to accommodate the longer text? Thank you . Nelson
  • I am facing some stability issues with my solution using NodeMCU as WiFi shield. Main issue, the module hardly turns into AP mode, it insist on logging to my home WiFi router. Is there any way I can launch the WiFi shield in the AP mode? I do no…
  • Miscellaneus question. Why the WiFi shield firmware starts searching for my home wifi network and only after succesful log in it switches to the AP mode to allow data from/to CYTON to PC?? Why not start in AP mode ? Thanks. Nelson.
  • dear All. Fantastic support ! I have all the stuff under control now. My next step, I will try to run CYTON firmware on different PIC which is already available of the shelves in Argentina and along with ESP8266 Module (also available here) I will b…
  • Dear William. I was diving into the .pde's --- No way to touch nothing there. I am alone at home, the magnitude and complexity of the whole software architecture is overwhelming and impossible to be addressed by a single human being. So far, I will…
  • Sorry for becoming a pest. Did you think about running the CYTON design on a different micro? Perhaps we can get better performance on 16 or even more channels... Food for thought. So far, the PIC32MX250 128 seems to be doing happily the task, but f…
  • Hi William. BTW, thank you for your directions on OpenBCI-GUI. With reference to powering NodeMCU I am exploring a couple of options. My first attempt will be to use only the ESP8266 module and power the whole system with a "D" type Alkaline battery…
