FatFs - Generic FAT File System Module


layer

FatFs is a generic FAT file system module for small embedded systems. The FatFs is written in compliance with ANSI C and completely separated from the disk I/O layer. Therefore it is independent of hardware architecture. It can be incorporated into small microcontrollers with limited resource, such as AVR, 8051, PIC, ARM, Z80, 68k and etc. Also Petit FatFs module for tiny microcontrollers is available here.

Features

Application Interface

FatFs module provides following functions to the applications. In other words, this list describes what FatFs can do to access the FAT volumes.

Device Control Interface

Since the FatFs module is a file system layer, it is completely separated from physical devices, such as memory card, harddisk and any type of storage devices. FatFs accesses the storage device via a simple interface described below. The low level device control module is not a part of FatFs module. It is provided by implementer. Also sample implementations for some platforms are available in the downloads.

Resources

The FatFs module is a free software opened for education, research and development. You can use, modify and/or redistribute it for personal projects or commercial products without any restriction under your responsibility. For further information, refer to the application note.
