Shinichiro Nakamura / Mbed 2 deprecated SDCARD_PFF

This is Petit FAT File System Module for mbed NXP LPC1768. The ported library from http://elm-chan.org/fsw/ff/00index_p.html made by Mr. ChaN. The connection is same as SDCard library here http://mbed.org/projects/cookbook/wiki/SDCard . If you need change a pin, You can find the definition at libpff/connect.h :)

Dependencies: mbed
