Public Member Functions
void	begin (void)
	Initialize the SPI instance. More...
void	end (void)
	Deinitialize the SPI instance and stop it. More...
void	beginTransaction (SPISettings settings)
	This function should be used to configure the SPI instance in case you don't use the default parameters set by the begin() function. More...
void	endTransaction (void)
	settings associated to the SPI instance. More...
uint8_t	transfer (uint8_t _data)
	Transfer one byte on the SPI bus. More...
uint16_t	transfer16 (uint16_t _data)
	Transfer two bytes on the SPI bus in 16 bits format. More...
void	transferWrite (void *_buf, size_t _count)
	send several bytes. More...
void	transferRead (void *_buf, size_t _count)
	receive several bytes. More...
void	transfer (void *_buf, size_t _count)
	Transfer several bytes. Only one buffer used to send and receive data. More...
void	transfer (void *_bufout, void *_bufin, size_t _count)
	Transfer several bytes. One buffer contains the data to send and another one will contains the data received. More...
void	setBitOrder (BitOrder)
	Deprecated function. Configure the bit order: MSB first or LSB first. More...
void	setDataMode (uint8_t _mode)
