2 years ago Sure, here is the below logic which I have implemented for firmware change.
For 5 min, in firmware count of 11000 is mentioned, but currently this records for only 3 mins, so that means 3 mins represents 11000, so for 1 min it will be 11000/3, and for 5 min it will be (11000/3)*5 = 11000 *(5/3)
5 mins represents 3 mins ----> 11000 ----> then for 1 min ----> (11000/3) ----> for 5 mins ----> (11000/3)5 = (11000)(5/3)
15 mins represents 9 mins ----> 33000 ----> then for 1 min ----> (33000/9) ----> for 15 mins ----> (330000/9)15 = (33000)(5/3)
30 mins represents 18 mins ----> 66000 ----> then for 1 min ----> (66000/18)----> for 30 mins ----> (66000/18)30 = (66000)(5/3)
Same will continue for 15 mins, and other time intervals.
The above image contains the modified part, this is the only place where the firmware is modified, the commented part is the actual OpenBCI firmware, where as the top one without comments is modified by multiplying 5/3 to each time interval.It looks like this fix will need to be resolved in the firmware. Keeping this thread active until it is resolved and a new firmware version is released. Removing the 5.1.0 tag for this issue.
This issue is under active development and investigation by OpenBCI team.

2 years ago Even much of the current SD card doc text is not entirely correct. It looks like many of the files from the past don't have the correct footer.

2 years ago We have realized that there is a line of GUI code that must be incorrect in DataSourceSDCard.pde where is assumes Cyton+Daisy SD card file sampling rate is 125Hz . Cyton+Daisy, while limited to streaming 125Hz, seems to be saving to SD card at 250hz. The Docs have been updated to say this, but it now requires a change in the GUI to correct this.
We have ongoing work to fix the Cyton SD card functionality at the Firmware level.

1 year ago User requesting the "offline mode" for SD card. Example: start streaming data with the GUI and walk away from the computer. Entire recording should still be saved to SD card even though the GUI will throw popup saying no new data in X seconds.

Deploying fix for this to development branch now.

https://openbci.com/forum/index.php?p=/discussion/2552/recording-crashes-with-sd-card-and-other-issues#latest
This could be a firmware issue or maybe the wrong commands are sent to the board from the GUI. This is worth looking into to determine the root cause.
Expected
Record SD card files with maximum file size specified in Control Panel. Files should have no errors and playback fine in GUI v5.
