virtual void SPISoft::begin ( )

virtual

begin(): Initializes the SPI bus by setting SCK, MOSI, and SS to outputs, pulling SCK and MOSI low, and SS high.

Implements SPIBase.

virtual void SPISoft::beginTransaction ( SPISettings mySettings )

inlinevirtual

beginTransaction(): Initializes the SPI bus using the defined SPISettings.

Implements SPIBase.

virtual void SPISoft::end ( )

inlinevirtual

end(): Disables the SPI bus (leaving pin modes unchanged).

Implements SPIBase.

virtual void SPISoft::endTransaction ( )

inlinevirtual

endTransaction(): Stop using the SPI bus. Normally this is called after de-asserting the chip select, to allow other libraries to use the SPI bus.

Implements SPIBase.

void SPISoft::setDelay ( uint8_t dly )

inline

Set microsecond delay for the SCK signal. Impacts SPI speed.

unsigned char SPISoft::transfer ( unsigned char val )

inlinevirtual

transfer(), transfer16()

SPI transfer is based on a simultaneous send and receive: the received data is returned in receivedVal (or receivedVal16). In case of buffer transfers the received data is stored in the buffer in-place (the old data is replaced with the data received).

    receivedVal = SPI.transfer(val)
    receivedVal16 = SPI.transfer16(val16)
    SPI.transfer(buffer, size)

Implements SPIBase.
