The Intel Joule is a wifi and Bluetooth® enabled development platform for the Internet of Things.
For more info about the Intel Joule platform go to:
Setting up your Intel Joule
Everything you need to get started with the Joule is in the Intel Getting Started Guide located at:
https://intel.com/joule/getstarted
Don't forget to configure your Joule's wifi connection and update your Joule to the latest firmware image!
Example program
Save the following code into a file called main.go.
package main
import (
"time"
"gobot.io/x/gobot"
"gobot.io/x/gobot/drivers/gpio"
"gobot.io/x/gobot/platforms/intel-iot/joule"
)
func main() {
e := joule.NewAdaptor()
led := gpio.NewLedDriver(e, "103")
work := func() {
gobot.Every(1*time.Second, func() {
led.Toggle()
})
}
robot := gobot.NewRobot("blinkBot",
[]gobot.Connection{e},
[]gobot.Device{led},
work,
)
robot.Start()
}
You can read the full API documentation online.
Cross compiling for the Intel Joule
Compile your Gobot program run the following command using the command
line from the directory where you have your main.go file:
$ GOARCH=386 GOOS=linux go build .
Then you can simply upload your program over the network from your host computer to the Joule
$ scp main root@<IP of your device>:/home/root/blink
and then execute it on your Joule (use screen to connect, see the Intel setup steps if you don't recall how to connect)
$ ./blink
At this point you should see one of the onboard LEDs blinking. Press control + c to exit.
To update the program after you made a change, you will need to scp it over once again and start it from the command line (via screen).
Pin Mapping
The Gobot pin mapping for the Intel Joule uses the same numbering as the MRAA library does, as documented here:
https://software.intel.com/en-us/pin-mapping-for-carrier-board-joule
Of special note are the pins that control the build-in LEDs, which are pins 100 thru 103, as used in the example above.
The i2c interfaces on the Intel Joule developer kit board require that you terminate the SDA & SCL lines using 2 10K resistors pulled up to the voltage used for the i2c device, for example 5V.
