From e6cd91ca0b64800d365745cb0b767eff85feaf0f Mon Sep 17 00:00:00 2001 From: savelij13 Date: Thu, 11 Sep 2025 09:36:45 +0300 Subject: [PATCH] fatfs v0.07e Nov 03,2009: - Separated out configuration options from ff.h to ffconf.h. - Added a configuration option, _LFN_UNICODE. - Fixed f_unlink() fails to remove a sub-dir on _FS_RPATH. - Fixed name matching error on the 13 char boundary. - Changed f_readdir() to return the SFN with always upper case on non-LFN cfg. --- doc/00index_e.html | 30 +++-- doc/00index_j.html | 27 ++--- doc/css_e.css | 2 +- doc/css_j.css | 2 +- doc/en/appnote.html | 96 +++++++++++---- doc/en/chdir.html | 12 +- doc/en/chdrive.html | 10 +- doc/en/chmod.html | 10 +- doc/en/close.html | 8 +- doc/en/dinit.html | 2 +- doc/en/dioctl.html | 7 +- doc/en/dread.html | 2 +- doc/en/dwrite.html | 2 +- doc/en/fattime.html | 2 +- doc/en/filename.html | 14 +-- doc/en/forward.html | 9 +- doc/en/getfree.html | 15 ++- doc/en/gets.html | 9 +- doc/en/lseek.html | 50 ++++---- doc/en/mkdir.html | 10 +- doc/en/mkfs.html | 15 ++- doc/en/mount.html | 12 +- doc/en/open.html | 43 ++++--- doc/en/opendir.html | 12 +- doc/en/printf.html | 28 +++-- doc/en/putc.html | 10 +- doc/en/puts.html | 12 +- doc/en/read.html | 12 +- doc/en/readdir.html | 15 ++- doc/en/rename.html | 26 +++-- doc/en/sfatfs.html | 2 +- doc/en/sfileinfo.html | 2 +- doc/en/stat.html | 2 +- doc/en/sync.html | 10 +- doc/en/truncate.html | 10 +- doc/en/unlink.html | 18 ++- doc/en/utime.html | 12 +- doc/en/write.html | 13 ++- doc/ja/appnote.html | 89 +++++++++++--- doc/ja/chdir.html | 12 +- doc/ja/chdrive.html | 9 +- doc/ja/chmod.html | 14 ++- doc/ja/close.html | 8 +- doc/ja/dinit.html | 2 +- doc/ja/fattime.html | 2 +- doc/ja/filename.html | 14 +-- doc/ja/forward.html | 9 +- doc/ja/getfree.html | 15 ++- doc/ja/gets.html | 7 +- doc/ja/lseek.html | 31 ++--- doc/ja/mkdir.html | 12 +- doc/ja/mkfs.html | 7 +- doc/ja/mount.html | 6 + doc/ja/open.html | 39 ++++--- doc/ja/opendir.html | 14 ++- doc/ja/printf.html | 13 ++- doc/ja/putc.html | 8 +- doc/ja/puts.html | 8 +- doc/ja/read.html | 10 +- doc/ja/readdir.html | 21 +++- doc/ja/rename.html | 20 ++-- doc/ja/sfatfs.html | 2 +- doc/ja/sfileinfo.html | 6 +- doc/ja/stat.html | 12 +- doc/ja/sync.html | 9 +- doc/ja/truncate.html | 8 +- doc/ja/unlink.html | 16 ++- doc/ja/utime.html | 16 ++- doc/ja/write.html | 11 +- doc/patches.html | 18 --- doc/updates.txt | 13 ++- src/00readme.txt | 10 +- src/diskio.h | 2 +- src/ff.c | 264 ++++++++++++++++++++++-------------------- src/ff.h | 172 ++++----------------------- src/option/syncobj.c | 52 +++++---- 76 files changed, 918 insertions(+), 636 deletions(-) delete mode 100644 doc/patches.html diff --git a/doc/00index_e.html b/doc/00index_e.html index c32b9da..7eb4cd0 100644 --- a/doc/00index_e.html +++ b/doc/00index_e.html @@ -3,8 +3,7 @@ - - + ELM - FAT File System Module @@ -16,20 +15,21 @@

        Considerations on porting to various platform

        Basic considerations on porting

        The FatFs module is assuming following terms on portability.

        • ANSI C
          The FatFs module is a middleware that written in ANSI C. There is no platform dependence, so long as the compiler is in compliance with ANSI C.
        • Size of integer types
          -The FatFs module assumes that size of char/short/long are 8/16/32-bit and int is 16 or 32 bit. These correspondence are defined in integer.h. This will not be a problem on most compilers. When any conflict with existing definitions is occured, you must resolve it with care.

        How to port

        +

        You need to provide only low level disk I/O functions that required by FatFs module and nothing else. If a working disk module for the target is already existing, you need to write only glue functions to attach it to the FatFs module. If not, you need to port any other disk module or write it from scratch. All defined functions are not that always required. For example, disk write function is not required in read-only configuration. Following table shows which function is required depends on configuration options.

        The FatFs module supports long file name (LFN) from revision 0.07. The two different file names, SFN and LFN, of a file is transparent in the file functions except for f_readdir function. To enable LFN feature, set _USE_LFN to 1 or 2, and add a Unicode code conversion function ff_convert and ff_wtoupper to the project. This function is available in cc*.c. The LFN feature requiers a certain working buffer in addition. The buffer size can be configured by _MAX_LFN corresponding to the available memory size. The size of long file name will reach up to 255 characters so that the _MAX_LFN should be set to 255 for full featured LFN operation. When the size of working buffer is insufficient for the given file name, the file function will fail with FR_INVALID_NAME. When enable the LFN feature with re-entrant feature, _USE_LFN must be set to 2. In this case, the file funciton allocates the working buffer on the stack. The working buffer occupies (_MAX_LFN + 1) * 2 bytes so that the caller's stack must be a sufficient size considering the working buffer.

We are the Japanese, Chinese and Korean have tens of thousands of characters. Unfortunately, it requires a huge OEM-Unicode bidirectional conversion table and the module size will be drastically increased that shown in the table. As the result, the FatFs with LFN will not able to be implemented to most 8-bit microcontrollers including AVR. This is the reason why I had not been interested in implementing the LFN feature for a long time :-)

Description

-

The f_sync function performs the same process as f_close function but the file is left opened and can continue read/write/seek operations to the file. This is suitable for applications that open files for a long time in writing mode, such as data logger. Performing f_sync of periodic or immediataly after f_write can minimize risk of data loss due to a sudden blackout or an unintentional disk removal. However f_sync immediataly before f_close has no advantage because f_close performs f_sync in it. This function is not available in read-only configuration.

    説明

    f_mkfs関数はFATファイル・システムをドライブ上に作成します。リムーバブル・メディアのパーテーショニング・ルールとしてはFDISK形式とSFD形式があり、メモリ・カードではFDISK形式が普通です。この関数は複数区画には対応していないので、その物理ドライブの既存の区画は全て削除され、全体が一つの区画になります。

    FATタイプ(FAT12/FAT16/FAT32)は、その論理ドライブ上のクラスタ数によってのみ決定される[FAT仕様書より]決まりになっていて、それ以外の要因はありません。したがって、どのFATタイプになるかはドライブ・サイズと指定されたクラスタ・サイズに依存します。クラスタ・サイズは大きくするほど性能が上がり、逆にディスク利用効率は落ちます。
