Arduino for STM32

I've tested with a disco F407, LSE is not fitted so PC14 and PC15 are free.
Using default blink sketch using those pins and it works.
Maybe pio do some extra config preventing to use them...
Test with Arduino IDE.

Which board you select to build?
Code?

My guess is it support libmaple core and not the stm32 core. https://github.com/DCS-Skunkworks/dcs-b ... d-Hardware

So a port should be done to support the stm32 core.

It will be called automatically as it replace the weak function.

Simply redefine the system core clock config:

@stevestrong This menu is part of the libmaple core: https://github.com/rogerclarkmelbourne/Arduino_STM32/blob/master/STM32F1/boards.txt#L446 That is true, just that STM32F1XX/GD32F1XX Boards by stm32duino. is not known. Guess it is linked to dandrown package json file. @fpiSTM could you eventually...

Unfortunately not. This menu is not in the stm32 core.

Thanks @stevestrong nice to see you back

Did you evaluate to use other boards which are supported: - STM32WB5MM-DK : BLE supported thanks STM32duinoBLE - NUCLEO-WL55JC: LoRa supported thanks STM32LoRaWan or RadioLib Adding the WBA general purpose to Arduino should not be so hard as I provide a script to add a new serie. The main drawback i...
