Before using this library on OSX, you'll need to install the libusb and libusb-compat libraries.
This is easily done using the Homebrew OSX package manager. (Other OSes will need similar installation using their respective package managers)
brew install libusb libusb-compat$ go get github.com/hink/go-blink1const (
USBVendorID = 10168
USBProductID = 493
)USB IDs
var OffState = State{Duration: time.Duration(10) * time.Millisecond}OffState helper
type Device struct {
Device *libusb.Device // USB device
DefaultFadeTime time.Duration // Default time to fade between states
CurrentState State // Current state of the Blink(1)
}Device Thingm Blink(1) USB device
func OpenNextDevice() (device *Device, err error)OpenNextDevice opens and returns the next available Blink(1) device
func (b *Device) Close()Close communication channel to Blink(1)
func (b *Device) RunPattern(pattern *Pattern) (err error)RunPattern executes a predefined pattern
func (b *Device) SetState(state State) (err error)SetState sets the blink(1) to a specific state
type Pattern struct {
Repeat uint // How many times to repeat
RepeatDelay time.Duration // Delay between repeats
States []State // Slice of states to execute in pattern
}Pattern is a Blink(1) blink pattern
type State struct {
Red uint8 // Red value 0-255
Green uint8 // Green value 0-255
Blue uint8 // Blue value 0-255
LED uint8 // which LED to address (0=all, 1=1st LED, 2=2nd LED)
FadeTime time.Duration // Fadetime to state
Duration time.Duration // Duration of state after FadeTime
}State is a Blink(1) light state
const (
LEDAll uint8 = iota
LED1
LED2
)
LED helper constants, used to target specific LED's on the sides of Blink(1).
