The Idea
Please, don’t do it again... I would like to make a monitoring application which can transfer data
- ver the cloud,
for example Temperature, Humidity, Alarms
Develop and Deploy IoT Application ...Demystified... The Idea I - - PowerPoint PPT Presentation

Ingredients
- Embedded-side application (HW + SW) to collect and
upload data
- Server-side application to temporarily store in transit
data
- (Different) Client-side applications to retrieve and
consume data

System Architecture
SLIDE 5
Embedded Side: Hardware
- The Platform, in this case, is the electronic object that
will embed our application
- IoT = Internet Of Things
- In many cases “Small Things”...
- Not much space… we have to make it as small as
possible
- Use a Microcontroller
SLIDE 6
What About TCP/IP Interface?
- TCP/IP is a pretty much complicated protocol
- It has been developed during ‘70 by a group of
engineers
- You don’t want to do it again...
- Use a specialized Module
- Wiznet W5100

HW Setup (Demo)
Wiznet Microcontroller LEDs Sensors
SLIDE 8
Embedded Side: SW
- Lots of IDE for Microcontroller C code development
○ Not easy to use and understand ○ C language is pretty complex
- What about a Graphic Environment? It will reduce code
- verhead and simplify application development :-)
○ Yes, it is scalable if you use it in the right way… ○ Yep, it could be debugged like a text based… ○ Yeah, it can be simulated as well…

What is This?
- We are going to use Flowcode
- Flowcode is a Graphic Integrated Development
Environment
- It looks like a flowchart, but allow you to program
Microcontrollers
SLIDE 10
Using a Component
- Inside Flowcode a lot of complex problems could be
easily solved using a component
- A component is a set of APIs that allow you to interface
a complex peripheral inside your flowchart
- In Flowcode, CAN, USB, Ethernet are all components
- Besides APIs, components require also an initial
configuration, in the form of, so called, “extra properties”
- A component is added to a project simply
Dragging&Dropping it inside the project itself

Server Side: Dweet.io
- M2M server for IoT application
- Does not require any setup or sign on, you
just need to push data
- Free for public data, 1,99$/month for locking
a dweet (plus 30 days of storage)
- Basically like twitter for devices (things)
