Detailed Description

Contains the configuration data for a VMXResource whose VMXResourceType is SPI.

Constructor & Destructor Documentation

SPIConfig() [1/2]

SPIConfig::SPIConfig ( uint32_t  bitrate )

inline

SPIConfig constructor; initializes bitrate, sets remaining value to defaults.

Parameters

bitrate

The SPI Clock Bitrate

SPIConfig() [2/2]

SPIConfig::SPIConfig ( uint32_t  bitrate, uint8_t  mode, bool  cs_active_low, bool  msbfirst  )

inline

SPIConfig constructor; initializes values with the provided input parameters *.

Parameters

bitrate	The SPI Clock bitrate
mode	The SPI Mode (0-3)
cs_active_low	true if the SPI CS signal is active low; false if SPI CS signal is active high
msbvirst	true if the most significant Bit is transmitted first, false if the least-significant bit is transmitted first

Member Function Documentation

Copy()

virtual bool SPIConfig::Copy ( const VMXResourceConfig *  p_config )

inlinevirtual

Copies the contents of the source VMXResourceConfig object into this object.

NOTE: The source object's VMXResourceType must match this object's VMXResourceType.

Parameters

[in]

p_config

The source VMXResourceConfig object from which to copy configuration data into this object.

Implements VMXResourceConfig.

GetCopy()

virtual VMXResourceConfig* SPIConfig::GetCopy ( ) const

inlinevirtual

Instantiates a copy of the configuration data.

NOTE: The caller is responsible to delete the object returned from this method.

Implements VMXResourceConfig.

SetMode()

void SPIConfig::SetMode ( uint8_t  mode )

inline

Sets the configured SPI mode, which must be a value from 0-3.

Invalid mode input values are coerced to a value from 0-3.
