Thanks for the contribution.

Did you intend to add support for the STM32F3xx series in MicroPython? Are there particular F3 MCUs that you need support for?

Yeah Im intending support of STM32Fxxx series. There are all cards and specifications. I just add with way you provided in Readme file.

All files are provided from STMicroelectronics github repository https://github.com/STMicroelectronics/STM32CubeF3 version 1.11.2

I quoted all family devices because if they will publish new devices, I can see which devices are absent in next releases then I can also add them.

I just wanna add this devices and I mentioned, because of supply conductivity.

Note that adding the CMSIS and HAL code here is just part of adding support for STM32F3xx in MicroPython. There's still quite a bit of work that needs to be done in MicroPython's stm32 port to make it all work.

[Zaryob]

If there is a way to testing it and make it fully working i can do it. But I dont know how it would be actually.

[Zaryob]

And also I can import other cards that i use if I get it.

To get an idea of what's required to add support for a new MCU series, see here: micropython/micropython#6911

got it. Gonna test it then reply as nearly as possible.

Closing because this MCU is old and we do not want to support it in MicroPython. See further details at comment here: micropython/micropython#6955 (comment)
