2. ABOUT SPEAKER
3. KOTLIN WITH IOT APPLICATIONS • Popular use case of Kotlin for Android app development • Extended use case to have Kotlin run on Backend, just like Java language based on JVM • What else? KOTLIN WITH IOT APPLICATIONS • Popular use case of Kotlin for Android app development • Extended use case to have Kotlin run on Backend, just like Java language based on JVM • What else?
4. DISCLAIMER
5. KOTLIN NATIVE How about having Kotlin to run on device like Raspberry Pi?
6. NOT KOTLIN NATIVE
7. WITH KOTLIN NATIVE Kotlin Source Code Kotlin/Native Compiler Intermediate Representation LLVM BINARY 0100101.. Frontend Backend
8. WHAT TO BUILD? • A lighthouse device. • Read the status of CI pipeline. • Display the CI status of trunk branch: GREEN (passed), YELLOW (running) and RED (failed). Example for Build light indicator
9. LET’S DO THIS
10. TERMS konanc: Kotlin/Native compiler cinterop: Kotlin/native interoperability – create Kotlin binding for native lib armhf: Raspberry PI 3 B model architecture
11. RUN THE APP
12. VERIFY
13. CROSS- PLATFORM COMPILING
14. CROSS- PLATFORM COMPILING
15. RUN ON THE PI
16. MANIPULATE THE HARDWARE
17. WHAT I HAVE LEARNED You need to learn a bit about hardware along the way Not so much tutorials on this topic yet Controlled experiment
