IoT with Esquilo and AngularJS
+
What is Esquilo?
● IoT connectivity + Arduino usability + KISS philosophy
● NOT a Linux & Arduino mashup
● NOT a cloud-controlled widget
● Complete IoT solution (hardware + software + cloud)
Everything is Built In
Web IDE
● Stored in flash
● Multi-file source editor
● Syntax highlighting
● Source level debugger
○ Breakpoints
○ Stepping
○ Watches
○ Backtrace
● File manager
● Live console
Squirrel Language
● Embedded application is programmed in Squirrel
● Very similar syntax to JavaScript or C++
● Includes hardware libraries plus Arduino emulation
● Your functions are callable as web services (from JavaScript,
Python, Java, C, etc.)
● Runs in isolated VM
Esquilo RPC
● Embedded functions are automatically brought out as web service
endpoints
● Data transferred in both directions with JSON
● Easy with any language that has an HTTP client (JavaScript,
Python, Java, C, Ruby, etc.)
Weather Station Demo
Weather Station Squirrel Code
Import sensor drivers
Create I2C instance on bus 0
Create sensor instances
getWeather() callable with POST
and GET automatically
Read sensors, populate return
object
Weather Station HTML
Weather Application
Controller
Gauge directive widgets
Weather Station App & Controller
Weather model
ERPC POST to call getWeather()
embedded Squirrel code
Returned as JSON object
Populate model - Angular data
binding takes care of the rest
