3. Agenda → Swift in Embedded Systems → How to setup your RaspberryPi → Adding Swift to your Pi → Swift with Pins → Demo → Lessons learned
4. Swift in Embedded Systems
5. Evolution of Swift
6. Enter... the Raspberry Pi
7. How to setup your RaspberryPi
8. Choosing the Operating System
9. ⚠
10. Adding Swift to your Pi
11. !
12. Setting up Swift → Download the Swift 3.1.1 binaries → Check the Swift version using swift —-version
13. Swift with pins
14. How to lay out our circuit?
15. ⚠ → To verify your connection use sudo apt-get install wiringpi → To setup the pin as an output we do gpio mode 13 out → To switch it on we do gpio write 13 1
16. Disclaimer
17. SwiftyGPIO // swift-tools-version:3.1 import PackageDescription let package = Package( name: "TestProject", dependencies: [ .Package(url: "https://github.com/uraimo/SwiftyGPIO.git", majorVersion: 0) ] )
18. Setting up the Led import SwiftyGPIO import Foundation class PinService: NSObject { private let gpios: [GPIOName: GPIO] private let selectedPin: GPIO override init() { self.gpios = SwiftyGPIO.GPIOs(for: .RaspberryPi3) guard let pin = gpios[.P27] else { fatalError("Unable to initialise the GPIO pin") } self.selectedPin = pin self.selectedPin.direction = .OUT } }
19. Switching ON/OFF func switchLed(status: String) -> Int { if status == "ON" { selectedPin.value = 1 } else { selectedPin.value = 0 } return selectedPin.value }
20. Led on/off
21. Berlin Train System
22. Setting up Vapor
23. Demo !
24. What have we done?
25. Lessons learned → You can connect your RPi to your computer and share the internet via Ethernet cable.
