Classes
class	SPI::SPISettings
	A class that binds settings for configuring SPI transmissions. More...

Namespaces
	SPI
	This namespace bundles an interface to the SPI hardware subsystem on the AVR ATMega328p (Arduino Uno) and ATMega2560 (Arduino Mega) microcontrollers. It provides logical cohesion for functions implement the Master portion of the SPI protocol and prevents namespace collisions.

Enumerations
enum	SPI::ByteOrder { SPI::kLsbFirst, SPI::kMsbFirst }
	An enumeration that defines the byte order for multibyte SPI transmissions. More...
enum	SPI::SpiMode { SPI::kSpiMode0, SPI::kSpiMode1, SPI::kSpiMode2, SPI::kSpiMode3 }
	An enumeration that defines the modes available for SPI transmissions. More...

Functions
void	SPI::enable ()
	Enable the SPI subsystem for transmission. More...
void	SPI::disable ()
	Disable the SPI subsystem, precluding further transmissions. More...
void	SPI::configure (SPISettings settings)
	Set the configuration of SPI subsystem to match the needs of the system you are going to communicate with. More...
uint8_t	SPI::transmit (uint8_t data)
	Transmit a single byte using the SPI subsystem. More...
uint16_t	SPI::transmit16 (uint16_t data)
	Transmit a word-sized integer (two bytes) using the SPI subsystem. The order in which the bytes are sent is determined by the bit order configuration that has been set. More...
uint32_t	SPI::transmit32 (uint32_t data)
	Transmit a long-word-sized integer (four bytes) using the SPI subsystem. The order in which the bytes are sent is determined by the bit order configuration that has been set. More...
void	SPI::transmit (uint8_t *buffer, size_t count)
	Transmit an array of bytes using the SPI subsystem. The bytes are transmitted in array order. More...
