I have a question I'm trying to figure out. I want to collect ambulatory EEG data for a longer period of time and store it continuously to the SD card, but would like to be able to check in occasional

(Some SD cards that perfectly work on your P.C., will not be usable on the OBCI Card)

I'm trying to increase the sampling rate, store all the samples in the SD card and send every 8th sample to PC. For this I have done the following:

@Winslow_Strong's usb communication and @yj's SD card only methods eliminate the RFduino and allow for higher sample rates. Is there any other similar work/attempt? What is the current situtation/sta

- SD card is not supported yet (only dummy functions in firmware).

     If the sound track of the video is not already used, if you can associate some sounds to the images then you could use the sound card output of the  P.C. to "trigger , mark , tag" a sig

We are not using the SD card  and do not have a SD card inserted into our 32-bit board -- we are only streaming to the dongle.

With the V1 firmware it's noted in several other threads on the forum here, that long sessions (thru the dongle) are problematic in terms of freezing up or glitching. V1 firmware does allow long SD ca

P.S. : I am not sure but nearly sure that a very very  few  people use the SD card which blocks interrupt usage. (This blocking is to be checked...)

The original signal is not actually available over the radio link, as described on the docs link above. An averaging process is involved. The original signal IS available if recording to SD card.

My last suggestion is if you're building a prototype with little hardware/software knowledge, base it on a current revision. The 8bit board, as you said is deprecated. There's a lot more support and s

re: your custom SD card firmware. You can make this operate as you describe, since you have total control of the firmware you upload.

I am looking for the basic firmware I have to install on the ATmega328P-AU to get my board running. I want the SD card and especially the RFDuino 22301 module to activate so I can start working with t

My question is more: Is it possible to put a SD card in the board, mold it into our polymer and start it through the software (when we were able to connect the hardware to the software through the fir

it be to perform a training session on the PCB (SD) for example a swimming training and after coming out of the water sending the data to the software (or any software) and analyze it. We can't have

If you can live with collecting your samples to the SD card, not needing the real-time data stream to the computer -- then YJ's mods can do that,

Do not fret because of my stupidity. I first used the Arduino. I want to record 1-minute to SD card with Sample Rate 500Hz, I need to write these commands? Please help me. Thanks a lot.

You will not "see" the 2kHz it has to be recorded on the SD card...

On my 32bit v3, I often get the init timeout error when selecting the "write to sd" option.  I have to repeat the initialization several times to get it to work.  This never happens when I a
