# Beaglebone

The BeagleBone is an ARM based single board computer, with many different GPIO interfaces built in.

For more info about the BeagleBone platform click [here](http://beagleboard.org/Products/BeagleBone+Black).

## How to Install
```
go get -d -u github.com/hybridgroup/gobot/... && go install github.com/hybridgroup/gobot/platforms/beaglebone
```

## Cross compiling for the Beaglebone Black
You must first configure your Go environment for arm linux cross compiling

```bash
$ cd $GOROOT/src
$ GOOS=linux GOARCH=arm ./make.bash --no-clean
```

Then compile your Gobot program with

```bash
$ GOARM=7 GOARCH=arm GOOS=linux go build examples/beaglebone_blink.go
```

If you are running the official Angstrom or Debian linux through the usb->ethernet connection, you can simply upload your program and execute it with

```bash
$ scp beaglebone_blink root@192.168.7.2:/home/root/
$ ssh -t root@192.168.7.2 "./beaglebone_blink"
```

## How to Use

```go
package main

import (
	"time"

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

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

	beagleboneAdaptor := beaglebone.NewBeagleboneAdaptor("beaglebone")
	led := gpio.NewLedDriver(beagleboneAdaptor, "led", "P9_12")

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

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

	gbot.AddRobot(robot)

	gbot.Start()
}
```
