After attempting to run the Python code user.py (which has now been updated and runs a little better, thank you), I get an error about not being able to stream data because there is no SD card install

and should easily be handled by any class10 SD card,Also admin verified 512 byte block writes in the range of 0.0007 secs ~ 0.731428 MBps with a class10 card, which I still feel is slow given these c

Dhruv, I just merged your new topic / question "MicroSD write speed" with the previous thread.

Hi,Sorry, I have not looked into the assembly code yet, but I was wondering what would be the speed requirement for the microSD card.

That said, it would be possible to run the 32 channel system that you envision while storing the data to the on-board SD card.

The 8bit board uses an ATmega328P with Arduino UNO bootloader. The ATmega is an 8bit microcontroller with 32K bytes of code space, 1K of EEPROM, and ~2K of RAM. We're using ~25K of flash, and we have

I updated the drivers for my graphics card and that seemed to get the

(2) OpenGL errors usually indicate your graphics card drivers / software may not be up to date.  Or your graphics hardware does not support OpenGL at all.  Find out what hardware you have and visit th

plug it in but it does nothing. I have the 8-bit card. I've checked the device manager and can find nothing there either for the dongle. I have 3 USB ports on my computer and I've tried it in all 3,

Hi,<br />I'm coming to this discussion alittle late, but here you go.<br />There are issues writing to the SD card using the high level SDFat tools, for one.<br />Also, it make a big

Chip and William<br />I am starting on the SD card read with the RTOS system. I do not know witch of the variants I will use. There is a NillRTOS that is very small and may work.<br />At

William<br />Thanks. One of the libraries I am looking at essentially sets up an OS which does as you suggest. One thread services the Uart and the other services the sd card. This is new gr

Hi,<br />I've not yet used a phone to log data. I think that it would work great, though.<br />Again, in this context, I down think that the relative slowness of SD is due to the card its

TI hardware is actually two boards...a daughter card with the ADS1299 and a generic main board with a microcontroller to interface to the PC. I think that I've heard of people lifting off the ADS129

Hi there,<br />I wrote some (much?) of the OpenBCI code on the Sourceforce/Github repository. We/I did not use an SD card in any of our work to date. We've always just streamed data to the PC

one with an Arduino Uno and write the data to a SD card. Issue is I am using the Arduino SD library and it does not write fast enough. Data comes in every 2 ms but it takes the card 20 ms or more t
