Types

type Device

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

Device is a handle to a BME280 device

func Open

func Open(conn *smbus.Conn, addr uint8, mode OpMode) (*Device, error)

Open opens a connection to a BME280 device at the given address.

func (*Device) Close

func (dev *Device) Close() error

func (*Device) Sample

func (dev *Device) Sample() (h, p, t float64, err error)

Sample returns the (compensated) Humidity, Pressure and Temperature data off the device.

type OpMode

type OpMode uint8

OpMode describes the operating modes of a BME280 device.

const (
	OpInvalid OpMode = iota
	OpSample1
	OpSample2
