I need to shut down the SD card that I am using to copy data from a SARA 412 AFF.
I had some problems with the power draw in the sleep mode. I have managed to localize the problem on the SD card. I use the SD.h library.
I find that using the SDfat.h could possibly reduce the power consumption. BUt i can’T get it to identify any card. The call to SD. begin() never ends
HAs anyone succeeded in using SdFat.h with Sara 412 AFF? Thank you
