Arduino for STM32

In fact since IDE 2.3.x, the debug has been reworked by Arduino.
I'm currently working to support the new way to support debug svd files.

Simply create your main. Then the copy the setup. And finally the loop in an infinite loop. Copy the bsp files in your project and that all folks.

HAL_I2S_MODULE_ENABLED is defined by default. You should check the system core clock config to see of the I2S is correctly configured. Then you can simply call the HAL I2S API. Pay attention to the IRQ handler definition if you are in Cpp file, it have to be prefixed by extern "C". You can...

By default, the SPI instance is mapped to the SPI1, anyway, it is easy to override it to use the SPI2 and linked pins. You can read the wiki: https://github.com/stm32duino/Arduino_Core_STM32/blob/main/libraries/SPI/README.md#change-default-spi-instance-pins So first way is simply to change pins at r...

Bonjour Yves et bienvenue.
You can find here an example of cube project to Arduino.

So you used dfu? And you shorten the boot0 pin? Then press reset?
The STM32CubeProgrammer is well installed?
The bord is recognized as stm32bootloader ?

This board is supported since 2.7.0:
https://github.com/stm32duino/Arduino_C ... /pull/2108

Simply update to the latest core.

Why?

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?
