@yj, thanks for having a look.  Yes, even recording to SD, channels 9-16 are all 0 for all frequencies 250-2k.  

to use several of the channels from the daughter card for EMG data using electrodes on the forearm. Is this plausible, given the relatively long cable run from the OpenBCI board and down the arm?  Wo

But since I do not use a daisy card ,  I did not bothered about adverse consequences...

"we are sending data packet at the same rate of 250SPS, and alternating sample packets between the on Board ADS1299 and the on Daisy ADS1299. The method takes an average of the current and most r

At 250Hz , it can be used with the "Processing's OBCI_ GUI"    but to record at higher sample rates on a SD you should use the Arduino "Serial Monitor". (Reset the card  before...)

I am trying to make a purchase but have to break it up over 2 Visa gift cards. It looks like the shopping cart only allows me to use 1 credit card as a payment method. What are my options? Does the Op

One issue is that we have an upper limit on the over-the-air data rate, so the higher sample rates are useful only if you're going to use the SD card for local storage, and then down-sample over the a

One test you could do is to record the data to an SD card, and then compare that data to the GUI or VIBE recorded data to see if there is some difference.

I'm interested in any means to increase the sample rate of OBCI.  The application is real-time neurofeedback, so I'm unsure that any solution involving an SD-card, e.g. http://openbci.com/forum/index.

So if I set up a separate power supply for the ADS daughter card and give the pin connections as mentioned above with a level shifter and flash chips code to my arduino uno it should work straightaway

You will need to mod your firmware to use the button, switch, or external io pins to control starting / stopping your sd card data collection. Perhaps you could usurp the PC / BLE switch to control th

data gets stored in the SD Card. Having done that, it will eliminate the need

Here is a similar recording saved to the SD card:

with a y-cable.  When saving the data to the SD card, the amplitude of the signal recorded on the daisy channels (9-16) are ~45 times higher compared to the channels on the main board (1-8).  This do

Have you started the SD card code for Simblee yet?

@jussijaatinenAt higher sample rates, the data needs to be sent to the SD card. You can down-sample to the computer.

good components that are working on your 8-bit card. Or just forget the 32-bit board until you have more experience with the 8-bit. It was not that long ago that your other thread was encountering ma
