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 An example of glue function to attach existing disk I/O module to FatFs.
|
|
integer.h Integer type definitions for FatFs.
|
|
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.
