I have to perform EEG of sleep in 5 different mammals of the Madrid Zoo for research on REM sleep. The device will be the Cyton board of OpenBci. In the first phase of the study I worked on the method

time working to get the Cyton to write to SD card - this captures the road I

Trying to playback data from SD card - using the following process:

2) Capture EEG signals via the SD Card

I want to use the SD card feature, but I cannot convert the

Now it has occurred to me that this is indeed an analog circuit (brain waves generating the initial AC voltage) feeding into 3.5mm headphone cables and then the PC sound card for digitization. To me,

Hi the v3.2.0 has been released! SD card writing is working great.

ok. release 3.2.0 with SD card  writing were made...

and ALL available commands for SD card ? i intend to use simple 'echo' commands for controlling the SD card params writing + time markers

ok, still problems with SD card writing/reading

I need the recorded files on the SD card, with correct time stamps recorded on the AUX channels.

I may have missed the link, though i looked around and found some tips about how to test noise, check the "square wave" signal on SD card (for cross-checking the sampling?).

the version of gui 2.1.2 records correctly in the Sd card but the new verrsion 3.1 does not record any file into sd card by performing the same steps. I am doing something wrong?

I don't think to make the SD card start writing automatically is going to be hard! You could for sure write a little code to make the control commands get sent to the sdProcessChar() function, then wi

Data is written to the SD card at 250Hz for the Cyton with Daisy even though the data is sent out over bluetooth at 125Hz.

Sample rate, SD card? That was it right?

My Cyton recorded fine last night, but I wanted to change the firmware to use the LED to ensure me it was still writing to the SD card and had not crashed.

I've now been able to acquire data on the SD-Card, and convert them using the OpenBCI GUI.

My Cyton board just stopped writing data to SD card.  It initiates and you can see the data stream in the GUI, but no SD file is created.  I tried multiple cards and none of them work.  Has anyone els

You'd also need to have a signal to stop your recording and flush the remaining buffer to the SD card. Seems like you could use one of the pushbuttons for this(?)
