LITTLEFS_FILE_BUFFER_SIZE

#define LITTLEFS_FILE_BUFFER_SIZE   (0)

File buffer size, if 0, dynamic allocation is used.

If set, only one file can be used at a time, must be program size (mtd page size is used internally as program size)

LITTLEFS_LOOKAHEAD_SIZE

#define LITTLEFS_LOOKAHEAD_SIZE   (128)

Default lookahead size.

Definition at line 43 of file littlefs_fs.h.

LITTLEFS_MIN_BLOCK_SIZE_EXP

#define LITTLEFS_MIN_BLOCK_SIZE_EXP   (-1)

The exponent of the minimum acceptable block size in bytes (2^n).

The desired block size is not guaranteed to be applicable but will be respected.

Definition at line 69 of file littlefs_fs.h.

LITTLEFS_PROG_BUFFER_SIZE

#define LITTLEFS_PROG_BUFFER_SIZE   (0)

Prog buffer size, if 0, dynamic allocation is used.

If set, it must be program size

LITTLEFS_READ_BUFFER_SIZE

#define LITTLEFS_READ_BUFFER_SIZE   (0)

Read buffer size, if 0, dynamic allocation is used.
