Types ¶

type Device ¶

type Device struct {
	Address uint16
	// contains filtered or unexported fields
}

Device wraps an I2C connection to a BlinkM device.

func New ¶

func New(bus drivers.I2C) Device

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)

Version returns the version of firmware on the BlinkM.
