I have never before given importance to graphics card drivers using linux. 

Yes, we are using 10 class Kingston 8 GB card which is working fine alone, i checked it by sending a, L , S, A and it start creating the file according to HEX name in EEPROM. I checked the schematic o

I'm not sure about recording higher frequencies to the SD card. Some previous threads on the forum here indicated that may not work as expected with the current firmware.

Dear OBCI Team;As we are working on custom cyton board i.e TI ADS1299-EVM board with chipkit dp32 with the openbci bootloader. Now we are trying to record data in sd card and everything is working fin

Respected Sir,I used 32 bit cyton board with WifFi shield. I want to used this unit for facial EMG signal detection. in many paper researcher used EMG signal of 50Hz to 500Hz bandwidth. in your GUI I

Hey William;As now we are working on chipkit-dp32 with ads1299 and using the defaultboard from openbci library. All the things working fine. I know the openbci and chipkit-dp32 pin_def.h have some cha

know a better way. I initially thought the Cyton card could be powering down from too much draw (??) when connected to this circuit but I get the same problems when I d/c this photoresistor circuit.

The cyton card is not recognized by the OpenBCI GUI...

/dev/ttyUSB0) and we write the data to the SD card for offline analysis. Now, the problem is that the system works generally fine, but in some sessions one channel suddenly is switched off (becomes z

just a glance at your code and i'm wondering if you are using hardware or software SPI because the spi runs at 4Mbps so I assume the bottleneck is the sd card. You schematic says "seeed microsd&q

We're sorry about the SD card situation, but you can read the details on the above link. The Simblee processor has limitations.

You can find arduinos writing to an sd card all over the web but you can't get your device to do it? I thought I get the firmware going in a few days but I assumed your device was working.

re: SD card on Ganglion. This is not supported in the firmware due to hardware restrictions of the Simblee processor discovered only after the SD card was initially tested. There are more details here

I also noticed that the sd card stores data in an ascii hexadecimal format but binary would be 1/2 the size. I have been alone for a long time now and spent a lot of time meditating. I have some inter

1- My code is working fine, the issue was sd card and accelerometer, I disabled all of two in code.

I found that restarting problem is due to sd card and accelerometer code so I disabled those things and now restarting problem has been solved. But unfortunately no signal on GUI  

Interferring with the data streaming should not be an issue as I will only be talking to the RTC just prior to streaming the data to the SD card.

Hmm, that sounds like a very high end graphics card. DId you say you checked around to see if there is a special graphics board driver compatible with OpenGL and your version of Linux? (What Linux?) I
