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 cheap microcontrollers, such as 8051, PIC, AVR, SH, Z80, H8, ARM and etc..., without any change. Petit FatFs module is also available here.
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 the 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.
