Types

type Config

type Config struct {
	Address uint8
}

Config is the configuration for the TMP102.

type Device

type Device struct {
	// contains filtered or unexported fields
}

Device holds the already configured I2C bus and the address of the sensor.

func New

func New(bus drivers.I2C) Device

New creates a new TMP102 connection. The I2C bus must already be configured.

func (*Device) Configure

func (d *Device) Configure(cfg Config)

Configure initializes the sensor with the given parameters.

func (*Device) Connected

func (d *Device) Connected() bool

Connected checks if the config register can be read and that the configuration is correct.

func (*Device) ReadTemperature

func (d *Device) ReadTemperature() (temperature int32, err error)

Reads the temperature from the sensor and returns it in celsius milli degrees (°C/1000).
