1FatFs Module Source Files R0.10b (C)ChaN, 2014
6 ffconf.h Configuration file for FatFs module.
7 ff.h Common include file for FatFs and application module.
8 ff.c FatFs module.
9 diskio.h Common include file for FatFs and disk I/O module.
10 diskio.c An example of glue function to attach existing disk I/O module to FatFs.
11 integer.h Integer type definitions for FatFs.
12 option Optional external functions.
14 Low level disk I/O module is not included in this archive because the FatFs
15 module is only a generic file system layer and not depend on any specific
16 storage device. You have to provide a low level disk I/O module that written
17 to control your storage device.
23 FatFs module is an open source software to implement FAT file system to
24 small embedded systems. This is a free software and is opened for education,
25 research and commercial developments under license policy of following trems.
