Hi, I have a doubt about interrupt priority.Let's say we have two ISRs for two interrupts: interrupt A and interrupt B, where A has a higher priority than B.If the ISR of B is running and an interrupt A arrives, then the ISR B is interrupted, that of...
We are currently seeing issues while trying to get UART communication working : we have have 2 stm32h7 (STM32H753) boards connected via RS-232. On board 1 we are sending 4kB of data each second and on board 2 we are receiving this data.Tx on board 1 ...

Hi everyone,I using STM32L443 MCU . If we write 0xFF again on the page we have cleaned, can I not write the 0xBC parameter of the example we want on it? Do I have to clear the address I want to write before writing, even if it is 0xFF?
Is there a rule where to put code into main.c so that it stays there permanently? It happended to me now a couple of times that I added an interrupt callback function which suddenly disappeared. Are there areas in main.c where to safely put those?
Why?What happens if the respective pin is set as Push-Pull? And what happens if only the internal pullup is enabled and there's no external pullup?And there's no point to tell that the pin has to be set as "alternate function" - of course. That ST c...
