Macros | |
| #define | _FFCONF 80960 |
| #define | _FS_TINY 0 |
| When _FS_TINY is set to 1, FatFs uses the sector buffer in the file system object instead of the sector buffer in the individual file object for file data transfer. This reduces memory consumption 512 bytes each file object. More... | |
| #define | _FS_READONLY 0 |
| Setting _FS_READONLY to 1 defines read only configuration. This removes writing functions, f_write(), f_sync(), f_unlink(), f_mkdir(), f_chmod(), f_rename(), f_truncate() and useless f_getfree(). More... | |
| #define | _FS_MINIMIZE 0 |
| The _FS_MINIMIZE option defines minimization level to remove API functions. More... | |
| #define | _USE_STRFUNC 1 |
| To enable string functions, set _USE_STRFUNC to 1 or 2. More... | |
| #define | _USE_MKFS 1 |
| To enable f_mkfs() function, set _USE_MKFS to 1 and set _FS_READONLY to 0. More... | |
| #define | _USE_FASTSEEK 0 |
| To enable fast seek feature, set _USE_FASTSEEK to 1. More... | |
| #define | _USE_LABEL 0 |
| To enable volume label functions, set _USE_LABEL to 1. More... | |
| #define | _USE_FORWARD 0 |
| To enable f_forward() function, set _USE_FORWARD to 1 and set _FS_TINY to 1. More... | |
| #define | _CODE_PAGE 1252 |
| The _CODE_PAGE specifies the OEM code page to be used on the target system. Incorrect setting of the code page can cause a file open failure. More... | |
| #define | _USE_LFN 0 |
| The _USE_LFN option switches the LFN feature. More... | |
| #define | _MAX_LFN 255 |
| Maximum LFN length to handle. More... | |
| #define | _LFN_UNICODE 0 |
| To switch the character encoding on the FatFs API to Unicode, enable LFN feature and set _LFN_UNICODE to 1. More... | |
| #define | _STRF_ENCODE 3 |
| When Unicode API is enabled, character encoding on the all FatFs API is switched to Unicode. This option selects the character encoding on the file to be read/written via string functions, f_gets(), f_putc(), f_puts and f_printf(). This option has no effect when _LFN_UNICODE is 0. More... | |
| #define | _FS_RPATH 0 |
| The _FS_RPATH option configures relative path feature. More... | |
| #define | _VOLUMES 1 |
| Number of volumes (logical drives) to be used. | |
| #define | _MULTI_PARTITION 0 |
| When set to 0, each volume is bound to the same physical drive number and it can mount only first primaly partition. When it is set to 1, each volume is tied to the partitions listed in VolToPart[]. More... | |
| #define | _MAX_SS 512 |
| Maximum sector size to be handled. Always set 512 for memory card and hard disk but a larger value may be required for on-board flash memory, floppy disk and optical disk. When _MAX_SS is larger than 512, it configures FatFs to variable sector size and GET_SECTOR_SIZE command must be implemented to the disk_ioctl() function. More... | |
| #define | _USE_ERASE 0 |
| To enable sector erase feature, set _USE_ERASE to 1. Also CTRL_ERASE_SECTOR command should be added to the disk_ioctl() function. More... | |
| #define | _FS_NOFSINFO 0 |
| If you need to know the correct free space on the FAT32 volume, set this option to 1 and f_getfree() function at first time after volume mount will force a full FAT scan. More... | |
| #define | _WORD_ACCESS 0 |
| The _WORD_ACCESS option is an only platform dependent option. It defines which access method is used to the word data on the FAT volume. More... | |
| #define | _FS_REENTRANT 1 |
| The _FS_REENTRANT option switches the re-entrancy (thread safe) of the FatFs module. More... | |
| #define | _FS_TIMEOUT 1000 |
| Timeout period in unit of time ticks. | |
| #define | _SYNC_t void * |
| O/S dependent type of sync object. e.g. HANDLE, OS_EVENT*, ID and etc.. | |
| #define | _FS_LOCK 8 |
| To enable file lock control feature, set _FS_LOCK to 1 or greater. The value defines how many files can be opened simultaneously. More... | |
