Developer Kit JavaScript Tools

• mraa – open source library for Galileo/Edison used API similar to the *MBED api (Intel Iot Devkit )

• io-js- open source library for Galileo/Edison used API similar to the Arduino API (Intel Labs China )

• johnny-five – Open source I/O library with plugins for various boards including Galileo (Gen2 demo upstairs)

• on/off – open source i/o library that can be used to manipulate ‘raw’ GPIO/PWM via sysfs interface

• i2c – node.js i2c library (uses sysfs)

• .

Raw filesystem IO using Bash.

• Not for the faint of heart.

• GPIO filesystem mappings vary from board to board.

• Pin Direction, Drive , Value all need to be set for each pin.• # Initializing digital output pin number 8

• echo -n "26" > /sys/class/gpio/export

• echo -n "out" > /sys/class/gpio/gpio26/direction

• echo -n "strong" > /sys/class/gpio/gpio26/drive

• echo -n "0" > /sys/class/gpio/gpio26/value

• echo -n "26" > /sys/class/gpio/unexport

Overview of

“libmraa” and

“libupm”

17

Libmraa

Defines the capabilities of GPIO pins,

Autodetection of Gen 1, Gen 2 and

Edison Arduino boards

Libupm

Defines the interaction of high level

sensors.

Buttons, Buzzers, LCD, LED, Light

Sensor, Servos, Rotary Angle Sensor,

Relays, Sound Sensors, temperature

sensors … more are added continually.

Purpose of Each Library

18 18

Libmraa – Object API (node.js)

Playing with GPIO is easy

var m = require("mraajs") # Import maajs module

var x = new m.Gpio(8) # Create a GPIO object for pin 8

x.dir(m.DIR_OUT) # Set GPIO direction to output

x.write(1) # Write to GPIO
