Raspi

This package contains the Gobot adaptor for the Raspberry Pi.

Getting Started

First you must install the appropriate Go packages

go get -d -u github.com/hybridgroup/gobot/... && go install github.com/hybridgroup/gobot/platforms/raspi

Cross compiling for the Raspberry Pi

You must first configure your Go environment for linux cross compiling

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

Then compile your Gobot program with

$ GOARM=6 GOARCH=arm GOOS=linux examples/raspi_blink.go

Then you can simply upload your program over the network from your host computer to the Raspi

$ scp raspi_blink pi@192.168.1.xxx:/home/pi/

and execute it on your Raspberry Pi with

$ ./raspi_blink

Example

package main

import (
        "time"

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

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

        r := raspi.NewRaspiAdaptor("raspi")
        led := gpio.NewLedDriver(r, "led", "7")

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

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

        gbot.AddRobot(robot)

        gbot.Start()
}
