The Professional Toolchain: arduino-cli, PlatformIO, Testing and CI

10 Lektionen in dieser Stufe

1. Building and Uploading from the Terminal with arduino-cli
   Install cores and libraries, compile and upload without the IDE. · Lab: Compile and upload a sketch for two different boards with one shell script.
2. Reproducible Builds: Pinning Core and Library Versions
   Record exact dependency versions so the same source gives the same binary later. · Lab: Create a build profile with pinned versions and rebuild on a second computer or clean folder.
3. PlatformIO Projects, Environments and platformio.ini
   Structure a project with several board environments and declared dependencies. · Lab: Convert a sketch into a PlatformIO project that builds for AVR and ESP32.
4. Compiler Warnings, Static Analysis and Automatic Formatting
   Raise warning levels, run a static analyser and apply a consistent code style. · Lab: Enable all warnings on an old project, fix every finding and format the code.
5. Separating Logic from Hardware for Testability
   Move decisions into plain C++ that does not depend on pins or timing functions. · Lab: Extract the thermostat decision logic into a hardware-free class.
6. Unit Tests on the PC with a Test Framework
   Write and run automated tests in the native environment. · Lab: Write ten tests for the extracted logic including edge cases and make them pass.
7. Fakes and Mocks for Sensors, Time and Buses
   Replace hardware and the clock with controllable stand-ins. · Lab: Test timeout behaviour by advancing a fake clock instead of waiting.
8. On-Target Tests and Hardware-in-the-Loop Rigs
   Run tests on the real board and let a second board stimulate and observe it. · Lab: Build a rig where one board presses the device's inputs and checks its outputs automatically.
9. Continuous Integration: Build and Test on Every Push
   Configure a hosted pipeline that compiles all environments and runs native tests. · Lab: Add a pipeline file, push a breaking change and watch it fail, then fix it.
10. Release Artifacts, Version Stamping and Build Metadata
    Embed version and commit identifiers in firmware and publish binaries from tagged builds. · Lab: Make the device report its version and commit over serial and produce a release binary from a tag.

Abschlussprojekt

A repository for one of your earlier projects that builds for two boards with pinned dependencies, runs unit tests on the PC and on the target and passes a CI pipeline on every push.
