Member Function Documentation

virtual bool BaseBlockDriver::readBlock	(	uint32_t	block,
		uint8_t *	dst
	)

pure virtual

Read a 512 byte block from an SD card.

Parameters

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

Returns: The value true is returned for success and the value false is returned for failure.

Implemented in SdBlockDriverEX.

virtual bool BaseBlockDriver::readBlocks	(	uint32_t	block,
		uint8_t *	dst,
		size_t	nb
	)

pure virtual

Read multiple 512 byte blocks from an SD card.

Parameters

[in]	block	Logical block to be read.
[in]	nb	Number of blocks to be read.
[out]	dst	Pointer to the location that will receive the data.

Returns: The value true is returned for success and the value false is returned for failure.

Implemented in SdBlockDriverEX.

virtual bool BaseBlockDriver::syncBlocks ( )

pure virtual

End multi-block transfer and go to idle state.

Returns: The value true is returned for success and the value false is returned for failure.

Implemented in SdBlockDriverEX.

virtual bool BaseBlockDriver::writeBlock	(	uint32_t	block,
		const uint8_t *	src
	)

pure virtual
