package beaglebone

import "gobot.io/x/gobot/platforms/beaglebone"

Package beaglebone provides the Gobot adaptor for the Beaglebone Black/Green, as well as a separate Adaptor for the PocketBeagle.

Installing:

go get gobot.io/x/gobot/platforms/beaglebone

Example:

package main

import (
	"time"

	"gobot.io/x/gobot"
	"gobot.io/x/gobot/drivers/gpio"
	"gobot.io/x/gobot/platforms/beaglebone"
)

func main() {
	beagleboneAdaptor := beaglebone.NewAdaptor()
	led := gpio.NewLedDriver(beagleboneAdaptor, "P9_12")

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

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

	robot.Start()
}
