Hi @bsatrom, thanks for the PR. Shouldn't a proper variant be added to https://github.com/stm32duino/Arduino_Core_STM32 in the first place?

@valeros 🤦 yep, you are correct. I will take care of that first and let you know when it's done.

PR submitted here: stm32duino/Arduino_Core_STM32#1987

@valeros PR above is approved and set to merge pending CI results. Slated for the 2.6.0 release.

@bsatrom @valeros hi, so it seems the current version of platform-ststm32 still doesn't support sparkfun micromod stm32f405 chips, is there any issue regarding Brandon's work to be merged here?
Sparkfun micromod STM32 boards are supported in:
https://github.com/stm32duino/Arduino_Core_STM32#sparkfun-boards

Brandon, I've tried your fork with the following setting in my platformio.ini:

platform = https://github.com/bsatrom/platform-ststm32.git
board = sparkfun_micromod_f405
framework = arduino

But a simple blink example build fails by complaining it can't find variant_SPARKFUN_MICROMOD_F405.h. Is there anything else I need to install?

Hey @diplodocuslongus I suspect that there needs to be an additional change to this PR to support Arduino core 2.6.0, see here for the 2.5.0 bump. I'll update this, but if you want to try yourself, open platform.json and change line 195 to

"version": "~4.20600.0"

Thanks for the PR, merged.
