Detailed Description

Holds the address and temperature for a single DS18B20 the 1-wire bus.

This hold the address, the last temperature, and whether the last retrieval was valid or not.

Constructor & Destructor Documentation

DS2482Device()

DS2482Device::DS2482Device

(

const DS24821WireAddress &

addr

)

Constructs a DS2482Device object from a 1-wire address DS24821WireAddress.

Member Function Documentation

getTemperatureC()

float DS2482Device::getTemperatureC ( ) const

inline

Gets the temperature in degrees Celsius.

Note that the resolution depends on the conversion bit settings. It ranges from 1/2 degree (9-bit) to 1/16 degree (12-bit)

getTemperatureF()

float DS2482Device::getTemperatureF ( ) const

inline

Gets the temperature in degrees Fahrenheit.

The DS18B20 uses Celsius internally, so the resolution is reflected in that. The degrees F is the actual converted value and may have more decimal places.

getValid()

bool DS2482Device::getValid ( ) const

inline

Gets the valid flag for this temperature reading.

When getting a list of temperatures using DS2482GetTemperatureForListCommand, it's possible that not every sensor will return a value. The getValid allows you to figure out which ones are valid.

setAddress()

void DS2482Device::setAddress ( const DS24821WireAddress &  addr )

inline

Sets the 1-wire address.

Parameters

addr	The address to set.

The addr is copied, so it does not need to be preserved after this call completes.

setTemperatureC()

void DS2482Device::setTemperatureC ( float  value )

inline

Sets the temperature in degrees Celsius.

Parameters

value

Temperature in degrees Celsius (as a float)

toString()

String DS2482Device::toString

(

)

const

Returns a string representation of this object including the address, temperature, and valid flag.
