CircleCI

CircleCI is a hosted cloud platform that provides hosted continuous integration, deployment, and testing to GitHub repositories.

CircleCI is configured by adding a file named circle.yml, which is a YAML format text file, to the root directory of the GitHub repository.

CircleCI automatically detects when a commit has been made and pushed to a repository that is using CircleCI, and each time this happens, it will try to build the project using platformio ci command. This includes commits to all branches, not just to the master branch. CircleCI will also build and run pull requests. When that process has completed, it will notify a developer in the way it has been configured to do so — for example, by sending an email containing the build results (showing success or failure), or by posting a message on an IRC channel. It can be configured to build project on a range of different Development Platforms.

Integration

Please make sure to read CircleCI Getting Started guide first.

dependencies:
    pre:
        # Install the latest stable PlatformIO
        - sudo pip install -U platformio

test:
    override:
        - platformio ci path/to/test/file.c --board=<ID_1> --board=<ID_2> --board=<ID_N>
        - platformio ci examples/file.ino --board=<ID_1> --board=<ID_2> --board=<ID_N>
        - platformio ci path/to/test/directory --board=<ID_1> --board=<ID_2> --board=<ID_N>

For more details as for PlatformIO build process please look into platformio ci.

Project as a library

When project is written as a library (where own examples or testing code use it), please use --lib="." option for platformio ci command

script:
    - platformio ci --lib="." --board=<ID_1> --board=<ID_2> --board=<ID_N>

Library dependecies

There 2 options to test source code with dependent libraries:

Install dependent library using Library Manager

dependencies:
    pre:
        # Install the latest stable PlatformIO
        - sudo pip install -U platformio

        # OneWire Library with ID=1 https://platformio.org/lib/show/1/OneWire
        - platformio lib -g install 1

test:
    override:
        - platformio ci path/to/test/file.c --board=<ID_1> --board=<ID_2> --board=<ID_N>

Manually download dependent library and include in build process via --lib option

dependencies:
    pre:
        # Install the latest stable PlatformIO
        - sudo pip install -U platformio

        # download library to the temporary directory
        - wget https://github.com/PaulStoffregen/OneWire/archive/master.zip -O /tmp/onewire_source.zip
        - unzip /tmp/onewire_source.zip -d /tmp/

test:
    override:
        - platformio ci path/to/test/file.c --lib="/tmp/OneWire-master" --board=<ID_1> --board=<ID_2> --board=<ID_N>

Custom Build Flags

PlatformIO allows to specify own build flags using PLATFORMIO_BUILD_FLAGS environment

machine:
    environment:
        PLATFORMIO_BUILD_FLAGS: -D SPECIFIC_MACROS -I/extra/inc

For the more details, please follow to available build flags/options.

Advanced configuration

PlatformIO allows to configure multiple build environments for the single source code using “platformio.ini” (Project Configuration File).

Instead of --board option, please use platformio ci --project-conf

test:
    override:
        - platformio ci path/to/test/file.c --project-conf=/path/to/platoformio.ini

Examples

  1. Custom build flags

dependencies:
    cache_directories:
        - "~/.platformio"

    pre:

        # pre-install PlatformIO development platforms, they will be cached
        - platformio platform install atmelavr atmelsam teensy
