void error

(

uint8_t

code

)

[inline]

Set SD error code.

Parameters:

[in]

code

value for error code.

int errorCode

(

)

const [inline]

Returns:

error code for last error. See Sd2Card.h for a list of error codes.

int errorData

(

)

const [inline]

Returns:

error data for last error.

bool init	(	uint8_t	sckRateID = SPI_FULL_SPEED,
		uint8_t	chipSelectPin = SD_CHIP_SELECT_PIN
	)

Initialize an SD flash memory card with default clock rate and chip select pin. See sd2Card::init(uint8_t sckRateID, uint8_t chipSelectPin).

Returns:

true for success or false for failure.

bool readBlock	(	uint32_t	block,
		uint8_t *	dst
	)

bool readCID

(

cid_t *

cid

)

[inline]

Read a card's CID register. The CID contains card identification information such as Manufacturer ID, Product name, Product serial number and Manufacturing date.

Parameters:

[out]

cid

pointer to area for returned data.

Returns:

true for success or false for failure.

bool readCSD

(

csd_t *

csd

)

[inline]

Read a card's CSD register. The CSD contains Card-Specific Data that provides information regarding access to the card's contents.

Parameters:

[out]

csd

pointer to area for returned data.

Returns:

true for success or false for failure.

bool readData

(

uint8_t *

dst

blockNumber

)

bool readStop

(

)

bool setSckRate

(

uint8_t

sckRateID

)

int type

(

)

const [inline]

Return the card type: SD V1, SD V2 or SDHC

Returns:

0 - SD V1, 1 - SD V2, or 3 - SDHC.
