Member Function Documentation

uint32_t SdCard::cardSize

(

void

)

Determine the size of a standard SD flash memory card

Returns:

The number of 512 byte data blocks in the card

uint8_t SdCard::init

(

void

)

Initialize a SD flash memory card.

Returns:

The value one, true, is returned for success and the value zero, false, is returned for failure.

uint8_t SdCard::readBlock	(	uint32_t	blockNumber,
		uint8_t *	dst
	)			[virtual]

Reads a 512 byte block from a storage device.

Parameters:

[in]	blockNumber	Logical block to be read.
[out]	dst	Pointer to the location that will receive the data.

Returns:

The value one, true, is returned for success and the value zero, false, is returned for failure.

Reimplemented from BlockDevice.

uint8_t SdCard::writeBlock	(	uint32_t	blockNumber,
		uint8_t *	src
	)			[virtual]

Writes a 512 byte block to a storage device.

Parameters:

[in]	blockNumber	Logical block to be written.
[in]	src	Pointer to the location of the data to be written.

Returns:

The value one, true, is returned for success and the value zero, false, is returned for failure.

Reimplemented from BlockDevice.
