What is FS.h and why do i need to use it with SD.h?
i trying out SD.h and i was using this tutorial and its says that i need 2 additional libs to use SD.h,
spi.h and fs.h
i understand why i need spi.h ( its api for spi protocol) but why do i need fs.h?
what does it do?
i tried to find some kind of documentation but i could find any.
i have few questions:
- what fs.h do
- why do i need it to use sd.h
- is there any good source where i could learn about file system on arduino?
