FatFs is a generic file system module to implement the FAT file system to small embedded systems. The FatFs is written in compliance with ANSI C, therefore it is independent of hardware architecture. It can be incorporated into cheap microcontrollers, such as 8051, PIC, AVR, SH, Z80, H8, ARM and etc..., without any change.
FatFs module provides following functions.
Since the FatFs module is completely separated from disk I/O layer, it requires following functions to lower layer to read/write physical disk and to get current time. The low level disk I/O module is not a part of FatFs module and it must be provided by user. The sample drivers are also available in the resources.
The FatFs module is a free software and is opened for education, research and development. You can use, modify and/or republish it for personal, non-profit or commercial use without any restriction under your responsibility.
