-FILES

-

-  ffconf.h   Configuration file for FatFs module.

-  ff.h       Common include file for FatFs and application module.

-  ff.c       FatFs module.

-  diskio.h   Common include file for FatFs and disk I/O module.

-  diskio.c   Skeleton of low level disk I/O module.

-  integer.h  Alternative type definitions for integer variables.

-  option     Optional external functions.

-

-  Low level disk I/O module is not included in this archive because the FatFs

-  module is only a generic file system layer and not depend on any specific

-  storage device. You have to provide a low level disk I/O module that written

-  to control your storage device.
