I was planning to make SD card automatically record when I turn on the board for my application. I intended to build off of one of the examples given and not the DefaultBoard. I also don’t need to use

* SD card

Also, I haven't seen the EMG data in real-time with the GUI because I'm collecting data at 500Hz, which doesn't stream over Bluetooth (only saves to SD card). For this next test I'll switch to 250Hz a

I scaled the data from the SD card according to this page. I used the wrong gain (24 instead of 1) and scaled it to uV, which is why the y-axis is too large.

I'm using a Cyton+Daisy board to record EEG and EMG data at 500Hz to an SD card while study participants walk on a treadmill.

I've got a Cyton + Daisy board with 16 channels. I used this code here (https://github.com/OpenBCI/OpenBCI_Cyton_Library/pull/96) to update the board firmware to save directly to an SD card, which let

thanks for the quick reply and ideas! So far, I don't see a relationship between SD card capacity and the recording loss. I am using four boards for the experiment and mostly 32gb SD cards (same model

Is there any correlation to the type or capacity of SD card being used? There is some speculation that larger capacity SD cards may have less reliability.

I am currently running a study with the Cyton+Daisy combo, in which participants wear sensors over the course of a workday. To record data continuously, I am writing the recordings to SD cards. The pr

Looking at the Cyton schematic, it seems as if the PIC32 uses SPI to communicate with the ADS1299, accelerometer, SD card, and Daisy bus. But on the PIC32's datasheet, it tells me that there are only

Thank you for the helpful and timely feedback. The new 16GB card I purchased arrived late yesterday and appears to be working just fine.

The threshold between SDXC (64GB and above) and SDHC (below 64GB), should allow you to use any sub 64GB card.

Thank you for the feedback. I have two boards in my possession. ! was successfully used with an older SD card in the past few months. Unfortunately no one seems to know where that card is at the momen

This may explain why the 64GB card uses a different standard, SDXC vs SDHC for the smaller cards.

Your output above seems to have some correlation to issues with the OpenGL, graphics library. This library depends upon having up to date graphics / card / chip drivers installed on your laptop. Pleas

I think we should update the Doc to say this information. I can confirm that these scale factors are declared in GUI 5.0.4 but aren't used for live data. It must be taken into account in BrainFlow. In

I just setup my cyton+daisy with the EEG electrode cap for the first time. I followed all the instructions from the website very carefully. When I click the "Start Data Stream" button, the T

CSV values are stored to SD card on the device itself. This is separate from how/where the GUI saves playback files based on data received from the device.
