Member Function Documentation

void modm::I2cDevice< I2cMaster, 10 , I2cWriteReadTransaction >::attachConfigurationHandler ( I2c::ConfigurationHandler handler )

inheritedinline

Attaches a configuration handler, which is called before a transaction, whenever the configuration has to be changed.

bool modm::I2cDevice< I2cMaster, 10 , I2cWriteReadTransaction >::isTransactionRunning ( )

inheritedinlineprotected

Returns: true when transaction is busy.

template<class I2cMaster >

modm::mcp990x< I2cMaster >::Mcp990x	(	Data &	data,
		uint8_t	address = `0x4d`
	)

Parameters

address I2C address, MCP990xT-1: 0x4c, -2: 0x4d, -A: adjustable, see datasheet

template<class I2cMaster >

bool modm::mcp990x< I2cMaster >::readExternalDiodeTemperature ( ExternalDiode diode )

Read external diode temperature sensor

Precondition: sensor is succesfully initialized

template<class I2cMaster >

bool modm::mcp990x< I2cMaster >::readInternalTemperature ( )

Read internal temperature sensor

Precondition: sensor is succesfully initialized

void modm::I2cDevice< I2cMaster, 10 , I2cWriteReadTransaction >::setAddress ( uint8_t address )

inheritedinline

Sets a new address of the slave device.

Parameters

address the slave address not yet shifted left (address < 128).

template<class I2cMaster >

bool modm::mcp990x< I2cMaster >::setExternalDiodeIdealityFactor	(	ExternalDiode	diode,
		uint8_t	idealitySetting
	)

Set external diode ideality factor See datasheet for values

bool modm::I2cDevice< I2cMaster, 10 , I2cWriteReadTransaction >::wasTransactionSuccessful ( )

inheritedinlineprotected

Returns: true when transaction did not return an error.
