Detailed Description

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

Member Function Documentation

virtual void SdSpiBase::begin ( uint8_t  chipSelectPin )

pure virtual

Initialize the SPI bus.

Parameters

[in]

chipSelectPin

SD card chip select pin.

Implemented in SdSpiSoft< MisoPin, MosiPin, SckPin >.

virtual void SdSpiBase::beginTransaction ( 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 in SdSpiSoft< MisoPin, MosiPin, SckPin >.

virtual void SdSpiBase::endTransaction ( )

virtual

End SPI transaction.

Reimplemented in SdSpiSoft< MisoPin, MosiPin, SckPin >.

virtual uint8_t SdSpiBase::receive ( )

pure virtual

Receive a byte.

Returns

The byte.

Implemented in SdSpiSoft< MisoPin, MosiPin, SckPin >.

virtual uint8_t SdSpiBase::receive ( uint8_t *  buf, size_t  n  )

pure 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.

Implemented in SdSpiSoft< MisoPin, MosiPin, SckPin >.

virtual void SdSpiBase::send ( uint8_t  data )

pure virtual

Send a byte.

Parameters
