23 Dec 2009 Added Software SPI capability. See Sd2Card.h Defining MEGA_SOFT_SPI allows an unmodified Adafruit GPS Shield to be used on Mega Arduinos. Software SPI works well with GPS Shield V1.1 but many SD cards will fail with GPS Shield V1.0. Added file ArduinoPins.h for pin definitions. More error printout in examples. 25 Nov 2009 Added new functions for SdFile class: dateTimeCallback(), dirEntry(), isRoot(), isSubDir, ls(), makeDir(), printDirName(), printFatDate(), printFatTime(), printTwoDigits(), rmDir(), and rmRStar(). Added new examples to test and illustrate use of new functions. Removed sdCard() from SdFile class. Fixed several bugs. 12 Nov 2009 Major rewrite of the version of SdFat that was included with the WaveRP library. This is a preview that is being released to obtain comments from several colleagues and future users.
