Arduino for STM32

Hi IMESHPEIRIS About the Serial, it misses the "Serial.begin(9600);" val1 is never reset to false ? Which board you used ? Hard to help without check which pin you used. I've made the test with a Nucleo F446RE with this sketch and it works as expected including the serial: int val = 0; #define ...

Yes but it has its own definition:
https://github.com/stm32duino/Arduino_C ... xx/WL5MOCH
and it is actually not supported.
Maybe it could work with WL55JC definition but which one you used the Nucleo? The generic ?

Which board you select? This mcu is not supported yet.

Hi,
in theory you could using the generic:

You don't enable the HAL_COMP_MODULE_ENABLED

The sketch is a cpp file not an header file. See the wiki and the HAL module management using hal_conf_extra.h.

This one is not added. You can add it following the wiki.
I don't understand why you "replaced" the ldscript as it doesn't exist.

One more detail: I'm actually using the ST-LINK_gdbserver, not openOCD. Not sure if that matters or not. OK so we do not talk about debugging STM32U0 thanks the Arduino IDE or you made a customization. About openOCD STM32U0xx support, a review is ongoing to add it: https://review.openocd.org/c ...

With Arduino IDE you have to enable the "optimize for debugging".
Anyway the openocd version included with the stm32 core does not support the U0. So you can't debug it.

I modified the "pins_arduino.h" file located in folder ..\Arduino15\packages\STMicroelectronics\hardware\stm32\2.8.1\cores\arduino You should avoid to change core's file. Next time you will update you will loose your change moreover it impact all other variants. Simply use the API to change the ...
