Types

type Device

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

func New

func New(i2c *machine.I2C, addressBits uint8) *Device

New returns ADT7410 device for the provided I2C bus and address. The ADT7410 has a default address of 0x48 (1001000). The last 2 bits of the address can be set using by connecting to the A1 and A0 pins to VDD or GND (for a total of up to 4 devices on a I2C bus). Also note that 10k pullups are recommended for the SDA and SCL lines.

func (*Device) Configure

func (dev *Device) Configure() (err error)

func (*Device) ReadTempC

func (d *Device) ReadTempC() float32

ReadTempC returns the value in the temperature value register, in Celcius

func (*Device) ReadTempF

func (d *Device) ReadTempF() float32

ReadTempF returns the value in the temperature value register, in Fahrenheit

func (*Device) ReadTemperature

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

ReadTemperature returns the temperature in celsius milli degrees (°C/1000)

type Error

type Error uint8

const (
	ErrInvalidID Error = 0x1
)

func (Error) Error

func (e Error) Error() string
