static uint8_t* SdVolume::cacheClear |
( |
void |
| ) |
[inline, static] |
Clear the cache and returns a pointer to the cache.
Used by the WaveRP recorder to do raw write to the SD card. Not for normal apps.

( |
void |
| ) |
const [inline] |
- Returns:
- The total number of clusters in the volume.
Definition at line 459 of file SdFat.h.
uint8_t SdVolume::clusterSizeShift |
( |
void |
| ) |
const [inline] |
- Returns:
- The shift count required to multiply by blocksPerCluster.
Definition at line 461 of file SdFat.h.
uint32_t SdVolume::dataStartBlock |
( |
void |
| ) |
const [inline] |
- Returns:
- The logical block number for the start of file data.
Definition at line 463 of file SdFat.h.
uint8_t SdVolume::fatCount |
( |
void |
| ) |
const [inline] |
- Returns:
- The number of FAT structures on the volume.
Definition at line 465 of file SdFat.h.
uint32_t SdVolume::fatStartBlock |
( |
void |
| ) |
const [inline] |
- Returns:
- The logical block number for the start of the first FAT.
Definition at line 467 of file SdFat.h.
uint8_t SdVolume::fatType |
( |
void |
| ) |
const [inline] |
- Returns:
- The FAT type of the volume. Values are 12, 16 or 32.
Definition at line 469 of file SdFat.h.
uint8_t SdVolume::init |
( |
Sd2Card & |
dev | ) |
[inline] |
uint8_t SdVolume::init |
( |
Sd2Card * |
dev | ) |
[inline] |
Initialize a FAT volume.
Try partition one first then try super floppy format.
- Parameters:
-
[in] | dev | The Sd2Card where the volume is located. |
- Returns:
- The value one, true, is returned for success and the value zero, false, is returned for failure. Reasons for failure include not finding a valid partition, not finding a valid FAT file system or an I/O error.

| [inline] |
uint8_t SdVolume::init |
( |
Sd2Card * |
dev, |
|
|
uint8_t |
part |
|
) |
| |
Initialize a FAT volume.
- Parameters:
-
[in] | dev | The SD card where the volume is located. |
[in] | part | The partition to be used. Legal values for part are 1-4 to use the corresponding partition on a device formatted with a MBR, Master Boot Record, or zero if the device is formatted as a super floppy with the FAT boot sector in block zero. |
- Returns:
- The value one, true, is returned for success and the value zero, false, is returned for failure. Reasons for failure include not finding a valid partition, not finding a valid FAT file system in the specified partition or an I/O error.

uint32_t SdVolume::rootDirEntryCount |
( |
void |
| ) |
const [inline] |
- Returns:
- The number of entries in the root directory for FAT16 volumes.
Definition at line 471 of file SdFat.h.
uint32_t SdVolume::rootDirStart |
( |
void |
| ) |
const [inline] |
- Returns:
- The logical block number for the start of the root directory on FAT16 volumes or the first cluster number on FAT32 volumes.
