The SD card mode works similarly to the FRAM Log Mode, except that the temperature and voltage data are stored into .txt files on the SD card. Each time the SD card log mode is started, a new LOG_#.TXT (# increments for the next file) is created under /root/DATA_LOG/.
Enter and exit SD card log mode the same way that you enter and exit FRAM log mode. Click Show SD Card Data to transfer the data from the most recently created LOG_#.TXT to the PC.
The super cap cannot power the SD card log mode for long periods of time, because the SD card consumes significantly more power.
