Are you the architect of Fat16 library? I am new to Arduino....Love Arduino, but puzzle by SD.h
I look at the examples included and header file
class is defined as SDClass and later renamed as SD?
if card, volume and root are to be used, why declared as private?
anyhow, does your Fat16 library work with Adafruit MicroSD?
SD is a wrapper for SdFat. When I wrote SdFat I designed three main classes, Sd2Card, SdVolume, and SdFile.
The Arduino group wrote a wrapper class to simplify I/O to SD cards that contains the three classes.
Since they correctly made these members private:
// These are required for initialization and use of sdfatlib
You can't easily integrate the functionality of both in one sketch.
You might want to look at SdFat without the wrapper since the version of SdFat in SD.h is very old. SdFat is here http://code.google.com/p/sdfatlib/downloads/list and betas/extras are here http://code.google.com/p/beta-lib/downloads/list.
