HELP ME KINDLY.... I have a project demo tommorow i have developed a ssvep based command selection (4 basic frequecies) I used cyton board and dongle ** I use **filters and CCA to detect SSVEP PROBLEM IS THAT Most of the times... SSVEP is not se…

Ok got you point thankyou

I just needed impedence check..that why i didnot set the filter of 50hz

@retiutut said: Fp1 and Fp2 should have the lowest impedance. Also, can you do this in the OpenBCI GUI send a screenshot of the GUI before and during impedance check, so I can have a look at the raw signals. this is of impedence at FP1…

Thankx alot brother> @wjcroft said: Read this regarding how the high amplifier INPUT impedance (1 gigaohm), means that skin impedances in the ranges you mentioned, are not actually an issue of any importance. https://openbci.com/foru…

Thanku> @wjcroft said: Read this regarding why you may be having difficulty with SSVEP. It's because your screen flashing is not 100% accurate. Some tests are mentioned that you can perform with a photodiode and provided program. htt…

@wjcroft said: Did you try the test mentioned? This verifies that your wiring and connections are all good. You can check the validity of your impedance measurements, by using a glob of paste to connect one cup (say channel 1) with re…

sure brother... i will share with you...

@retiutut said: @hansi Please, let's focus on getting good impedance signals first. Thank you for the additional information though. Try checking impedance on the forehead: Fp1 and Fp2 first. These sites do not normally have hair. …

@retiutut said: @wjcroft I think @hasni is close. Can you recommend or rephrase a test that can be done to ensure the board is functional? @Hasni said: I have used silver and gold cup electrodes and also bought a fresh Ten20 Paste still…

@retiutut said: You can only check impedance on one channel at a time for Cyton due to a limitation of the ADS1299 chip, as it injects a small amount of current into the channel. Doing this for multiple channels will distort the impedance reading…

a friend of mine told that he used Unity to build that GUI using C# language and i donot how he was linking unity app to ** MATLAB processings** if any one knows how he could have linked matlab processings do share with me

@wjcroft said: Hasni, hi. Please consider using Brainflow instead of LSL. Also by avoiding streaming the data first through the GUI Networking Widget, latency is further reduced. https://brainflow.org/ William Thankyou

@retiutut said: You can use the GUI to find the name of the Cyton Dongle serial port on all OS. Plug in dongle -> Open OpenBCI GUI -> Control Panel -> Cyton -> Manual -> See list of all connected Cyton Dongles Thanky…

_Till here i have done.. after wards i know nothing.. kindly help... _

@wjcroft said: They are microvolts. https://openbci.com/forum/index.php?p=/discussion/201/large-millivolt-data-values-fbeeg-full-band-eeg Thankyou

@wjcroft said: Hasni, hi. The CSV data format in the GUI recording files, is described completely in the header comment lines. William are these voltages (ofcourse not) ? Then what these values of exg channel 0 1 2 3 4…
