Are Arduino generic boards supported by platformio?

#1

I am considering using the STM32G030F6 MCU and I see that it’s supported as a generic board by android. GitHub - stm32duino/Arduino_Core_STM32: STM32 core support for Arduino

How do I select this generic board when defining a new platformio project? I don’t see it in the list of supported boards.

#2

It’s missing the board definitions, but they are in Add support for STM32G030 targets by brainelectronics · Pull Request #622 · platformio/platform-ststm32 · GitHub.

#3

Thanks @maxgerhardt, I will try to incorporate it in my project.

Are there similar files for STM32G070CBT6 ? This is another MCU I consider to use, with more ROM/RAM.

#4

You would just need to modify / duplicate the previous board JSON and modify the MCU, max flash and RAM and variant attributes to match what’s available in STM32Duino, aka for that MCU STM32G0xx/G070CBT.

Thanks @maxgerhardt. I found the RB file ./platforms/ststm32/boards/nucleo_g070rb.json and changed it to a CB version in the ‘boards’ directory of my project. it builds and I am waiting for the board to test it.
