Petit FatFs: Tiny FAT Filesystem

lbuild module: modm:fatfs.petit

Petit FatFs is a sub-set of FatFs module for tiny 8-bit microcontrollers. It can be incorporated into the tiny microcontrollers with limited memory even if the RAM size is less than sector size.

See http://elm-chan.org/fsw/ff/00index_p.html.

Configuration

To configure Petit FatFs for your project, create a <pffconf_local.h> file, which is included at the beginning of the config, thus overwriting the default settings. Please see the modm/ext/fatfs-petit/pffconf.h file for the available configuration options and their default values.

Example <pffconf_local.h> configuration:

// Enable directories: pf_opendir(), pf_readdir()
#define PF_USE_DIR 1

// Enabling writing: pf_write()
#define PF_USE_WRITE 1

// Use FAT12 file system
#define PF_FS_FAT12 1
#define PF_FS_FAT16 0
#define PF_FS_FAT32 0
