Function Documentation

SBC_SPI_INIT()

uint8_t SBC_SPI_INIT

(

void

)

IMPORTANT! THIS METHOD HAS TO BE DEFINED BY THE USER.

     The function has to initialze the SPI of the uC and will be called once during SBC_Init().
     In case, the SPI hardware is already initialized by some other code before, it can be left blank.

Return values

Method

has to return 0 if initialization was successful.

SBC_SPI_TRANSFER16()

uint16_t SBC_SPI_TRANSFER16	(	uint8_t	Upper,
		uint8_t	Lower
	)

IMPORTANT! THIS METHOD HAS TO BE DEFINED BY THE USER.

     The function will be called by the library everytime when a SPI communication is needed.
     The function proceeds a bidirectional 16-bit transfer to/from the SBC  .
     As some UCs only supports 8-Bit transfers, the input arguments are split in two 8-bit arguments.
     For further implementation details have a look at datasheet chapter 13.1 or at the Arduino-examples.

Parameters

Upper	The first 8 bit to transmit to the SBC.
Lower	The second 8 bit to transmit to the SBC.

Return values

The	function will return all 16 bits received from the SBC. Bit[15:8] are the first 8 bits received (Status-Information-Field). Bit[7:0] is the data-field transmitted of the SBC.
