This GitHub Action allows STM32 firmware binaries to be built from TrueSTUDIO C/C++ projects.

Note: By using TrueSTUDIO, you agree to its EULA.

• project: The path to one or more directories containing a TrueSTUDIO .project file, relative to the repository root. Bash pattern matching operators (including globstar) can be used to match multiple locations. By default, this is set to the repository root.
• build: [Project name]/[Build configuration] to build. Both the project name and build configuration can be regular expressions. If this input is set to all, all configurations for all projects are built. By default, this is set to all.

When a new GitHub release is created, build all firmware projects under the firmware directory of the repository, then upload example-project's firmware binary as a release asset:

name: Upload Firmware Release Asset

on:
  release:
    types:
      - created

jobs:
  build:
    name: Upload Firmware Release Asset
    runs-on: ubuntu-latest
    steps:
      - name: Checkout code
        uses: actions/checkout@v2
      - name: Build with TrueSTUDIO
        uses: carlalbrecht/atollic-truestudio-action@v1
        with:
          project: firmware/*
          build: .*/Debug
      - name: Upload firmware release asset
        uses: actions/upload-release-asset@v1
        env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
        with:
          upload_url: ${{ github.event.release.upload_url }}
          asset_path: ./firmware/example-project/Debug
          asset_name: example-project.hex
          asset_content_type: binary/octet-stream

Build outputs are located in the same directories as when the project is built through the TrueSTUDIO desktop interface - in a child directory inside the project directory, whose name matches the build configuration used.
