- 4. CEO of
- 5. Disclaimer Focus my talk on Arduino
- 6. allow me to talk about my credentials So, you know who’s talking in front of you :)
- 8. Start coding in QBasic in 1997
- 9. My first computer IBM XT 286 circa 1997
- 10. Been coding in awesome languages/Frameworks QBasic, Pascal, c, C++, Java, PHP, Bash, C#, Visual Basic, HTML, JavaScript, Python, Objective-C, Swift .NET, Qt/QML, Java ME/EE/SE, Android SDK, iOS SDK, Node.js, Arduino
- 11. 8 years in a row
- 12. The first & largest iOS & OSX developer community in Indonesia ID-Objective-C I’m the president of
- 13. 100+ Software Projects & Products
- 14. Good enough for me To Talk about software development :) ?
- 15. Disclaimer but I do have a bit of electronics background
- 16. My high school is Vocational School - Aviation Electronics
- 17. I took physics Major in ITB- Instrumentation sub major My Final project is about smart home - in 2003
- 18. As software developer, what do I learn when developing for hardware? Hopefully you will learn it too…
- 19. better “Integrated development Environments” As software developer, I want
- 20. vs Arduino IDE Sublime TexT with Stino
- 21. vs Arduino IDE Visual Studio with VS Micro
- 23. Demo
- 24. Implement Software engineering best practices As software developer, I do
- 25. Writing thousands LoC in one .ino file kinda sucks, right?
- 26. Multiple .ino files? Still doesn’t feels right It’s hard to reuse code
- 27. Arduino language is based on Wiring framework. Arduino IDE is based on Processing (in Java). Arduino language is implemented in C++ Arduino supports latest major C++ standard, C++11 DID YOU KNOW?
- 28. OOP the keyword is… Object-oriented Programming
- 29. C++ is OOP Language and…
- 30. OOP Inheritance Polymorphism Class & Object Constructor Destructor Operator overloading Encapsulation Composition Message Passing Interface Abstraction Method overriding Overloading
- 31. So this thousands LoC in main .ino, with the help of OOP, can become…
- 32. 29 LoC (including #includes) Not bad, no?
- 33. Highly readable code Highly modular and reusable code Highly maintainable code Teamwork-friendly
- 34. Abandon Arduino/Wiring framework! If you wanna really go full-pledge OOP for Arduino development,
- 36. void setup() { pinMode(13, OUTPUT); } void loop() { digitalWrite(13, HIGH); delay(1000); digitalWrite(13, LOW); delay(1000); } #include "Cosa/OutputPin.hh" #include "Cosa/Watchdog.hh" OutputPin ledPin(13); void setup() { Watchdog::begin(); } void loop() { ledPin.on(); delay(1000); ledPin.off(); delay(1000); } vs Arduino Cosa
- 37. Demo
- 39. Software Design Pattern Adapter Facade Singleton Decorator Filter Observer State Machine Builder Flyweight Factory Composite MVC DTO DAO Memento Mediator
- 40. Do in Software as much as possible As software developer, I will
- 41. Still swiTch off your raspberry Pi manually, without clean shutdown? Let’s take a look this case
- 42. Let’s create intelligent Shutdown button
- 43. As hardware engineer, you’ll create this
- 44. Or this… Pi Supply circuit
- 45. I’ll do this…
- 46. And a bit of code
- 47. Arduino Pro Mini $2 Relay module $2 Cables + switch $0.5 Total $4.5 Total Cost
- 48. Or you can buy one of these modules… Mausberry $14 Pi Supply €15
- 49. Leverage Cloud as much as possible As software developer, I will
- 50. MQTT MQTT Web app MQTT Broker Data storage & analytics Example scenario MQTT Web Socket Device Web dashboard Smartphone Cloud
- 51. MQTT MQTT Web app MQTT Broker Data storage & analytics Real example - our HomeX Smart Home Platform MQTT Web Socket HomeX Smart Stuff HomeX Dashboard HomeX App HomeX Cloud
