Variable Documentation

FNAME_FLAG_LC_BASE

const uint8_t FNAME_FLAG_LC_BASE = FAT_CASE_LC_BASE

Filename base-name is all lower case

FNAME_FLAG_LC_EXT

const uint8_t FNAME_FLAG_LC_EXT = FAT_CASE_LC_EXT

Filename extension is all lower case.

FNAME_FLAG_LOST_CHARS

const uint8_t FNAME_FLAG_LOST_CHARS = 0X01

Derived from a LFN with loss or conversion of characters.

FNAME_FLAG_MIXED_CASE

const uint8_t FNAME_FLAG_MIXED_CASE = 0X02

Base-name or extension has mixed case.

FNAME_FLAG_NEED_LFN

const uint8_t FNAME_FLAG_NEED_LFN

Initial value:

=
  FNAME_FLAG_LOST_CHARS | FNAME_FLAG_MIXED_CASE

LFN entries are required for file name.
