Dear Community,

Happy holidays everyone! Just wanted to let you know that STM32 (bluepill and blackpill) support has been added to the development branch.

It's based on latest STM32Duino platform and unlocks usage of the STM32 architecture beyond the legacy STM32F1 (older hardware) that MySensors had over the last years. BlackPill hardware is more recent and improved and with the STM32Duino base, we have a future-proof dependency.

Enjoy!
Many thanks to tekka and fallberg for support and code reviews!

@buxtronix thanks for the effort! Why not make a PR? 433MHz is a quite unique value proposition of MySensors. I'd recommend a quick search through the open issues on MySensors github, maybe some CC1101 support was requested already. In any way, I'd encourage to raise a PR to the development branch. Who knows, if we get some people engaged, maybe we can release a new official version of MySensors with improved hardware support.
Thx, Dirk.

@goblin feel free to share concrete error messages or questions. We might be able to help on well-described problems. Otherwise - hope ChatGPT can help you ;-)

Hi goblin, so you got MySGW compiled successfully now using the development branch in git? That's great to hear! I do not have experiences with RPi gateways, neither Domoticz. But I believe choosing the Ethernet option is the easiest to configure (see Domoticz). Does that work for you?

@goblin said in mysensors on rpi with NRF2401 with Domoticz:

fatal: destination path 'MySensors' already exists and is not an empty directory

Seems like you're trying to clone the MySensors git repo but there's already an existing MySensors folder. This is a typical git error message.

If you haven't given up yet, you could rename the Mysensors folder to something else and git-clone the development branch as advised by @mfalkvidd.

(As a general advise, if you are unsure, it might be an option to just ask ChatGPT about the error messages, describing your scenario. It knows git and Mysensors ;-))

@tnick I know this is an old post, but if it helps you - I've created support for STM32 based on latest STM32duino here. It's currently made to be backward compatible for the existing STM32F1 support, which is what you are struggling. But with a small change you can use the new STM32 HAL support. Let me know if you are interested to give it a try.
The longer term plan is to remove the existing (old) STM32F1 support in favor of the new and more general STM32 support. (If @mfalkvidd agrees ;-))
