How to get the compiled HEX?

[TomasHubelbauer]

Hello, is it possible to get the compiled HEX from the sketch?

Hi @TomasHubelbauer. Yes, you can do this.

The action's cli-compile-flags input allows you to pass arbitrary flags that will be used in the arduino-cli compile command that compiles the sketches. You can learn about all the available flags here:
https://arduino.github.io/arduino-cli/latest/commands/arduino-cli_compile/#options

There is an example of a configuration that uses arduino-cli compile's --export-binaries flag here: #18 (comment)

I tried this:

    - name: Compile the sketch
      uses: arduino/compile-sketches@v1 # https://github.com/arduino/compile-sketches
      with:
        sketch-paths: |
          - .
        cli-compile-flags: |
          - --output-dir="$PWD"

But it did not work. I am not sure if I need to use --build-path maybe or instead of $PWD use ., in any case, I found this worked:

cp /tmp/arduino-sketch-*/sketch-name.ino.hex sketch-name.hex

I added it to a script step and it works well enough for now until I figure out cli-compile-flags.
