How difficult would it be to program the Cyton to start writing directly to the SD card when you power on the board instead of having to interface with the computer, and to have the LED flash indicati

I have now acquired a SanDisk microSD card and will be testing this shortly.

After playing around with permissions and drivers I get a blue light on the USB dongle, a working /dev/ttyUSB0, a successful connection to the Cyton card, and even raw data via OpenBCI_Python.  Howeve

Hello,thanks for the amazing dev on the card and the shield.

Re: SD Card - did you test with a different card? I verified SD works for at least the 14second write.

The SD card on Cyton is for recording directly to a file on the SD, not for program storage. I don't think Ganglion has record capability yet. Best way to control your external remote device is with a

I also believe the SD card writing is "buffered", that is, data is streamed into a temporary array, then written to the card only as the buffer fills up. So the bursts of higher current woul

What is the amount of current consumed by the cyton board with SD Card. It is writtten in this blog http://eeghacker.blogspot.ch/2015/01/estimating-openbci-battery-life.html that it consumes 40mA with

Hello, I am trying ask via python to record on sd card at 1kHz, using v3.0.0

Highlighted in yellow is the SD-card holder. I am uncertain as to where to get this. Digikey has a bunch of SD-holder components, but I have not yet figured out if they are directly compatible re e.g.

I've been trying to get my Ganglion Board to write to SD Card with no success. I've tried updating the firmware with the current version on github (https://github.com/OpenBCI/OpenBCI_Ganglion_Library)

I want to connect my STM32 Discovery Microcontroller board with the Cyton board and I am not sure if we can do it via the SPI pins given for the daisy chain module. I want to extract data from the SD

@tskips were you able to try with a different SD card? 

v2.0.1 is stable... There may be an issue with your SD card. Nothing really significant changed here and the SD code should work. Has anyone else been able to get SD working with v2.0.1? Or 3.0.0?

I would like to use the SD card for the EEG recordings with the ganglion board, nevertheless while the BLE is working in parallel to the SD card a noise is created which I would like to omit. 

Thanks William, since I need to execute the experiment within two weeks I'll skip the development option and explore the SD card one, if none is good I'll end up carrying a laptop in a backpack  

Ok this is great. I will try to find an SD card and reproduce and put a patch out for beta7. Thanks! 

I was wondering if a python plugin could access the SD card read and write features of the board?If so, is there a scaffolding or a template similar to the provided python plugins one could start with

which makes me wonder whether the cause is actually something about the sd-card... (my current one is a 16 gb samsung, class 10, uhs speed 1)
