Can RP2040 build environment be supported?

[RobTillaart]

Is it possible to support the RP2040 build environment?

Would be appreciated

Found how to do it.

.arduino-ci.yml

platforms:
  rpipico:
    board: rp2040:rp2040:rpipico
    package: rp2040:rp2040
    gcc:
      features:
      defines:
        - ARDUINO_ARCH_RP2040
      warnings:
      flags:

packages:
  rp2040:rp2040:
    url: https://github.com/earlephilhower/arduino-pico/releases/download/global/package_rp2040_index.json


compile:
  # Choosing to run compilation tests on 2 different Arduino platforms
  platforms:

    # - due
    # - zero

Tested and it works

If this is a popular board, I wouldn't mind adding it to https://github.com/Arduino-CI/arduino_ci/blob/master/misc/default.yml

[RobTillaart]

Think it is pretty popular as there are several devboards and variations.
For me the yml file is also a 'guide' how other boards can be added, so no need to add it to default.yml imho.

It would be interesting to know what are the top 15 boards used.

[ianfixes]

My high level goal isn't necessarily to represent the most popular board, just to have enough boards defined that any given library developer will find at least one working arduino_ci platform for their library, out of the box.

[RobTillaart]

Imho you have enough boards supported. The ones I could think of

• AT TINY series (most interesting as these have very little RAM etc)
• NANO BLE
• RP2040
• Teensy

That said, when compiling the examples, is it possible to get info about sketch size and RAM usage?

When developing libraries I often want to know if code increases or decreases and by how much.
This is mostly an AVR thingy as these are the most limited wrt RAM.
( no this is not a request for a new feature, as I investigate this locally before pushing code )

Hi, I will test with STM32.
We had lot of librairies.

STM32 +1

@RobTillaart

This is my idea with the ARDUINO_CI_POST_UNIT_TEST_RUN_SCRIPT hook script that enables you to for instance capture build results by running avr-size and append the result to a csv file/send an email/push a chat message/etc (or maybe even just print to the screen).

This is present on my scripts branch pending a merge of #320.

@hlovdal on my local branch I've started reporting the "free bytes" (in the message at the end of each compilation step) to the test output, but I can see that we're getting to the point where machine-readable output is necessary.

Can you open an issue to track this idea? It sounds like you'd like a report of things that are more informational than pass/fail. Sizes and compilation times are 2 things that jump out at me there.

Regarding your issue about the hooks, I think it's a great idea! My first step for it is figuring out how to do it in a generic way. Happy to continue the discussion on that other issue
