This repository contains the FatFs library, developed by ChaN (Website), for use in hhuOS. The source code has not been changed in any way, except for ffconf.h, which contains the following changes:
# Disable real time clock functionality
sed -i "s/#define FF_FS_NORTC 0/#define FF_FS_NORTC 1/g" "source/ffconf.h"
# Set code page to 437 (U.S.)
sed -i "s/#define FF_CODE_PAGE 932/#define FF_CODE_PAGE 437/g" "source/ffconf.h"
# Enable LFN support
sed -i "s/#define FF_USE_LFN 0/#define FF_USE_LFN 1/g" "source/ffconf.h"
# Enable f_mkfs() function
sed -i "s/#define FF_USE_MKFS 0/#define FF_USE_MKFS 1/g" "source/ffconf.h"
# Set the amount of volumes to 10 (maximum)

| ff.c | FatFs module. |
| ffconf.h | Configuration file of FatFs module. |
| ff.h | Common include file for FatFs and application 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. |
| ffunicode.c | Optional Unicode utility functions. |
| ffsystem.c | An example of optional O/S related 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 it does not depend on any specific storage device. You need to provide a low level disk I/O module written to control the storage device that attached to the target system.
