#define FAT_DATETIME_SUPPORT   0

Controls FAT date and time support.

Set to 1 to enable FAT date and time stamping support.

Definition at line 54 of file fat_config.h.

#define FAT_DELAY_DIRENTRY_UPDATE   0

Controls updates of directory entries.

Set to 1 to delay directory entry updates until the file is closed. This can boost performance significantly, but may cause data loss if the file is not properly closed.

Definition at line 72 of file fat_config.h.

#define FAT_DIR_COUNT   2

Maximum number of directory handles.

Definition at line 111 of file fat_config.h.

#define FAT_FAT32_SUPPORT   SD_RAW_SDHC

Controls FAT32 support.

Set to 1 to enable FAT32 support.

#define FAT_FILE_COUNT   1

Maximum number of file handles.

#define fat_get_datetime	(	year,
		month,
		day,
		hour,
		min,
		sec		)	get_datetime(year, month, day, hour, min, sec)

Determines the function used for retrieving current date and time.

Define this to the function call which shall be used to retrieve current date and time.

Note:

Used only when FAT_DATETIME_SUPPORT is 1.

Parameters:

[out]	year	Pointer to a uint16_t which receives the current year.
[out]	month	Pointer to a uint8_t which receives the current month.
[out]	day	Pointer to a uint8_t which receives the current day.
[out]	hour	Pointer to a uint8_t which receives the current hour.
[out]	min	Pointer to a uint8_t which receives the current minute.
[out]	sec	Pointer to a uint8_t which receives the current sec.

#define FAT_LFN_SUPPORT   1

Controls FAT long filename (LFN) support.

Set to 1 to enable LFN support, set to 0 to disable it.
