Arduino for STM32

fpiSTM , if you care to look at the code, this is an issue in a file in Arduino_Core_STM32. https://github.com/stm32duino/Arduino_Core_STM32/blob/master/tools/platformio/platformio-build.py
is in your repository, so maintained by you I assume, and that sets a build flag for all cortex-m4 MCU's ...

OK, with the following change https://github.com/stm32duino/Arduino_C ... o?expand=1
I did manage to turn off the fpu stuff on from tools/platformio/platformio-build.py. Should I submit that as PR?

Awesome fpiSTM . Thanks so much. Haven't really had time to do anything with the stm32duino and my stm32wl55 board until today. Right now I am looking at getting it included in Platformio . I know you're not the one making the Platformio packages/framework definition, but I am running into an issue ...

Hey all, what are the chances of getting STM32WL support in the STM32Core?

unless you are using something truly bad, those crystals are spec'd to 20ppm and usually within 5ppm. so 5% is a little extraordinary.

I would first verify the cause. if it is indeed in the crystal, the hardware does allow LSE compensation - look to the reference manual. but unlikely to the ...

Hey all, I am using a custom board with an STM32F103C8 with an LSE and HSE clock using the STM32 core and the stm32duino RTC and LowPower libraries. I am putting my MCU to sleep using stop mode (deepsleep in stm32duino Low Power lingo) and wake up from an RTC alarm. Although the sensor says it will ...

Cool, thanks again for your help fpiSTM . I didn't know that doc existed. It helps a lot. But it turns out the IRQ was triggered by my STLink debugger. I am using it to upload the code. Even without actually debugging, it looks like after flashing the code, the STLink debugger triggers an interrupt ...

Ok, but can you elaborate a little on which registers I need to check? I am browsing through the STM32 reference manual and code, but there is so much of it that it's hard to figure out which ones I need to check, and how I can disable interrupts. Are there functions or specific registers that tell ...

Using the STM32 Arduino Core on an STM32F103C8, I am having an issue, probably with a 3rd party library, where some interrupt gets triggered, causing LowPower.deepSleep to wakeup straight away, instead of sleeping until the RTC alarm occurs. Is there a way to see what interrupts get triggered, and ...

To make the problem above clearer: In the small example that I gave, indeed issuing the Serial.flush() did solve the issue there, but in my real life code (too big to post here), I am making use of 3rd party libraries. There I have added Serial.flush() statements everywhere I debug print stuff, and ...
