Detailed Description

SPI class for access to SD and SDHC flash memory cards.

Member Function Documentation

void SdSpi::begin ( )

virtual

Initialize the SPI bus

Implements SdSpiBase.

void SdSpi::init ( uint8_t  divisor )

virtual

Set SPI options for access to SD/SDHC cards.

Parameters

[in]

divisor

SCK clock divider relative to the system clock.

Reimplemented from SdSpiBase.

uint8_t SdSpi::receive ( )

virtual

Receive a byte.

Returns

The byte.

Implements SdSpiBase.

uint8_t SdSpi::receive ( uint8_t *  buf, size_t  n  )

virtual

Receive multiple bytes.

Parameters

[out]	buf	Buffer to receive the data.
[in]	n	Number of bytes to receive.

Returns

Zero for no error or nonzero error code.

Implements SdSpiBase.

void SdSpi::send ( uint8_t  data )

virtual

Send a byte.

Parameters

[in]

data

Byte to send

Implements SdSpiBase.

void SdSpi::send ( const uint8_t *  buf, size_t  n  )

virtual

Send multiple bytes.

Parameters

[in]	buf	Buffer for data to be sent.
[in]	n	Number of bytes to send.

Implements SdSpiBase.

bool SdSpi::useSpiTransactions ( )

inlinevirtual

Returns

true - uses SPI transactions

Implements SdSpiBase.
