Arduino for STM32

No it is not yet released, will come in the coming weeks.
Anyway you can use the GitHub repository: https://github.com/stm32duino/Arduino_C ... repository

Post have hidden links. That's why I deleted the user and the post.

If you select the generic target, the default Serial pins are not PA9/PA10 but PA2/PA3:

You can change it at sketch level using the setRx ...

FIXED IT!!!

If you used the generic and not a dedicated variant then you can use the build_opt.h or the hal_conf_extra.h

Simply redefine it in your variant*.h file

Hi again new issue so new thread. we have USART3 on PC10/PC11 for debug output. But for some reason its outputting garbage.

I created a hello world in cubeIDE and it works fine there.
I am using the same clock config as cubeIDE so I know its not some strange clock sync issue.


Is it using HSE ...

Great. Could you share your code?
Here an example how to convert a cube example:
viewtopic.php?t=110

By default HSE_VALUE is 8MHz.
https://github.com/stm32duino/Arduino_C ... ault.h#L86

You have to define it to 25MHz.

About pin issue you probably made a mistake in your changes.

And use pin number PE14, PD13 and PD3 (no _) instead of pin name PE_14, PD_13 and PD_3.
