Detailed Description

template<typename SI, typename SO, typename SCK, typename CE, unsigned numNops>
class miosix::SoftwareSPI< SI, SO, SCK, CE, numNops >

Software implementation of the SPI protocol mode 0 (CPOL=0, CPHA=0 mode)

Parameters

SI	an instance of the Gpio class indicating the SPI input pin
SO	an instance of the Gpio class indicating the SPI output pin
SCK	an instance of the Gpio class indicating the SPI clock pin
CE	an instance of the Gpio class indicating the SPI chip enable pin
numNops	number of nops to add to the send loop to slow down SPI clock

static void miosix::SoftwareSPI< SI, SO, SCK, CE, numNops >::ceHigh ( )

inlinestatic

Pull CE high, indicating transmission end.

template<typename SI , typename SO , typename SCK , typename CE , unsigned numNops>

static void miosix::SoftwareSPI< SI, SO, SCK, CE, numNops >::ceLow ( )

inlinestatic

Pull CE low, indicating transmission start.

template<typename SI , typename SO , typename SCK , typename CE , unsigned numNops>

static void miosix::SoftwareSPI< SI, SO, SCK, CE, numNops >::init ( )

inlinestatic

Initialize the SPI interface

template<typename SI , typename SO , typename SCK , typename CE , unsigned numNops>

unsigned char miosix::SoftwareSPI< SI, SO, SCK, CE, numNops >::sendRecvChar ( unsigned char  data )

static

Send a byte and, since SPI is full duplex, simultaneously receive a byte

Parameters

data

to send

Returns

data received

template<typename SI , typename SO , typename SCK , typename CE , unsigned numNops>

unsigned int miosix::SoftwareSPI< SI, SO, SCK, CE, numNops >::sendRecvLong ( unsigned int  data )

static

Send an int and, since SPI is full duplex, simultaneously receive an int

Parameters

data

to send

Returns

data received

template<typename SI , typename SO , typename SCK , typename CE , unsigned numNops>

unsigned short miosix::SoftwareSPI< SI, SO, SCK, CE, numNops >::sendRecvShort ( unsigned short  data )

static

Send an unsigned short and, since SPI is full duplex, simultaneously receive an unsigned short

Parameters

data

to send

Returns

data received
