Spark

The Spark Core contains a Wi-Fi connected microcontroller. Once it connects to a Wi-Fi network, it automatically connects with a central server (the "Spark Cloud") and stays connected so it can be controlled from external systems, such as a Gobot program. To run gobot programs please make sure you are running default tinker firmware on the Spark Core.

How to Install

Installing Gobot with Spark support is pretty easy.

go get github.com/hybridgroup/gobot && go install github.com/hybridgroup/gobot/platforms/spark

How to Use

package main

import (
	"time"

	"github.com/hybridgroup/gobot"
	"github.com/hybridgroup/gobot/platforms/gpio"
	"github.com/hybridgroup/gobot/platforms/spark"
)

func main() {
	gbot := gobot.NewGobot()

	sparkCore := spark.NewSparkCoreAdaptor("spark", "device_id", "access_token")
	led := gpio.NewLedDriver(sparkCore, "led", "D7")

	work := func() {
		gobot.Every(1*time.Second, func() {
			led.Toggle()
		})
	}

	robot := gobot.NewRobot("spark",
		[]gobot.Connection{sparkCore},
		[]gobot.Device{led},
		work,
	)

	gbot.AddRobot(robot)

	gbot.Start()
}

Documentation

Overview

Package spark provides the Gobot adaptor for the Spark Core.

Installing:

go get github.com/hybridgroup/gobot && go install github.com/hybridgroup/gobot/platforms/spark

Example:

package main

import (
	"time"

	"github.com/hybridgroup/gobot"
	"github.com/hybridgroup/gobot/platforms/gpio"
	"github.com/hybridgroup/gobot/platforms/spark"
)

func main() {
	gbot := gobot.NewGobot()

	sparkCore := spark.NewSparkCoreAdaptor("spark", "device_id", "access_token")
	led := gpio.NewLedDriver(sparkCore, "led", "D7")

	work := func() {
		gobot.Every(1*time.Second, func() {
			led.Toggle()
		})
	}

	robot := gobot.NewRobot("spark",
		[]gobot.Connection{sparkCore},
		[]gobot.Device{led},
		work,
	)

	gbot.AddRobot(robot)

	gbot.Start()
}

Types

type Event

type Event struct {
	Name  string
	Data  string
	Error error
}

type SparkCoreAdaptor

type SparkCoreAdaptor struct {
	DeviceID    string
	AccessToken string
	APIServer   string
	// contains filtered or unexported fields
}

func NewSparkCoreAdaptor

func NewSparkCoreAdaptor(name string, deviceID string, accessToken string) *SparkCoreAdaptor

NewSparkCoreAdaptor creates new spark core adaptor with deviceId and accessToken using api.spark.io server as default

func (*SparkCoreAdaptor) AnalogRead

func (s *SparkCoreAdaptor) AnalogRead(pin string) (val int, err error)

AnalogRead reads analog ping value using spark cloud api

func (*SparkCoreAdaptor) AnalogWrite

func (s *SparkCoreAdaptor) AnalogWrite(pin string, level byte) (err error)

AnalogWrite writes analog pin with specified level using spark cloud api

func (*SparkCoreAdaptor) Connect

func (s *SparkCoreAdaptor) Connect() (errs []error)

Connect returns true if connection to spark core is succesfull

func (*SparkCoreAdaptor) DigitalRead

func (s *SparkCoreAdaptor) DigitalRead(pin string) (val int, err error)

DigitalRead reads from digital pin using spark cloud api

func (*SparkCoreAdaptor) DigitalWrite

func (s *SparkCoreAdaptor) DigitalWrite(pin string, level byte) (err error)

DigitalWrite writes to a digital pin using spark cloud api

func (*SparkCoreAdaptor) EventStream

func (s *SparkCoreAdaptor) EventStream(source string, name string) (event *gobot.Event, err error)

EventStream returns a gobot.Event based on the following params:

* source - "all"/"devices"/"device" (More info at: http://docs.spark.io/api/#reading-data-from-a-core-events) * name - Event name to subscribe for, leave blank to subscribe to all events.

A new event is emitted as a spark.Event struct

func (*SparkCoreAdaptor) Finalize

func (s *SparkCoreAdaptor) Finalize() (errs []error)

Finalize returns true if connection to spark core is finalized successfully

func (*SparkCoreAdaptor) Function

func (s *SparkCoreAdaptor) Function(name string, args string) (val int, err error)

Function executes a core function and returns value from request. Takes a String as the only argument and returns an Int. If function is not defined in core, it will time out

func (*SparkCoreAdaptor) Name

func (s *SparkCoreAdaptor) Name() string

func (*SparkCoreAdaptor) PwmWrite

func (s *SparkCoreAdaptor) PwmWrite(pin string, level byte) (err error)

PwmWrite writes in pin using analog write api

func (*SparkCoreAdaptor) Variable

func (s *SparkCoreAdaptor) Variable(name string) (result string, err error)

Variable returns a core variable value as a string
