   4 See defines in fat_opts.h:
   5
   6 FATFS_IS_LITTLE_ENDIAN  [1/0]
   7   Which endian is your system? Set to 1 for little endian, 0 for big endian.
   8
   9 FATFS_MAX_LONG_FILENAME [260]
  10   By default, 260 characters (max LFN length). Increase this to support greater path depths.
  11
  12 FATFS_MAX_OPEN_FILES
  13   The more files you wish to have concurrently open, the greater this number should be.
  14   This increases the number of FL_FILE file structures in the library, each of these is around 1K in size (assuming 512 byte sectors).
  15
  16 FAT_BUFFER_SECTORS
  17   Minimum is 1, more increases performance.
  18   This defines how many FAT sectors can be buffered per FAT_BUFFER entry.
  19
  20 FAT_BUFFERS
  21   Minimum is 1, more increases performance.
  22   This defines how many FAT buffer entries are available.
  23   Memory usage is FAT_BUFFERS * FAT_BUFFER_SECTORS * FAT_SECTOR_SIZE
  24
  25 FATFS_INC_WRITE_SUPPORT
  26   Support file write functionality.
  27
  28 FAT_SECTOR_SIZE
  29   Sector size used by buffers. Most likely to be 512 bytes (standard for ATA/IDE).
  30
  31 FAT_PRINTF
  32   A define that allows the File IO library to print to console/stdout.
  33   Provide your own printf function if printf not available.
  34
  35 FAT_CLUSTER_CACHE_ENTRIES
  36   Size of cluster chain cache (can be undefined if not required).
  37   Mem used = FAT_CLUSTER_CACHE_ENTRIES * 4 * 2
  38   Improves access speed considerably.
  39
  40 FATFS_INC_LFN_SUPPORT   [1/0]
  41   Enable/Disable support for long filenames.
  42
  43 FATFS_DIR_LIST_SUPPORT  [1/0]
  44   Include support for directory listing.
  45
  46 FATFS_INC_TIME_DATE_SUPPORT  [1/0]
  47   Use time/date functions provided by time.h to update creation & modification timestamps.
  48
  49 FATFS_INC_FORMAT_SUPPORT
  50   Include support for formatting disks (FAT16 only).
  51
  52 FAT_PRINTF_NOINC_STDIO
  53   Disable use of printf & inclusion of stdio.h
