	// contains filtered or unexported fields
}

Device wraps an I2C connection to a BlinkM device.

func New

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

This function only creates the Device object, it does not touch the device.

func (*Device) Configure

func (d *Device) Configure()

Configure sets up the device for communication

func (Device) FadeToRGB

func (d Device) FadeToRGB(r, g, b byte) error

FadeToRGB sets the RGB color on the BlinkM by fading from the current color to the new color.

func (Device) GetRGB

func (d Device) GetRGB() (r, g, b byte, err error)

GetRGB gets the current RGB color on the BlinkM.

func (Device) SetRGB

func (d Device) SetRGB(r, g, b byte) error

SetRGB sets the RGB color on the BlinkM.

func (Device) StopScript

func (d Device) StopScript() error

StopScript stops whatever script is currently running on the BlinkM.

func (Device) Version

func (d Device) Version() (major, minor byte, err error)
