Thanks Ray, this is helpful. I’m using OpenSprinkler fork based on 2.0.
I have a quick question for you – why there is a limit of 2GB on microSD card and FAT16? Standard Arduino SD library seems to handle well big cards (I’m using 32GB card) and FAT32 with no problems. Is it a hardware or software restriction?
