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...
STM32G473CCT uses the HAL library for writing flash pages.i have constructed some code to use the last FLASH page as NV memory.bool eeprom_write8(uint16_t address, uint8_t data) { return eeprom_write(address, &data, 1); } bool eeprom_write(uint16_...
I found a strange mismatch in the reference manual for the OTP memory size:Accordingly to the manual page 78 (https://www.st.com/resource/en/reference_manual/rm0385-stm32f75xxx-and-stm32f74xxx-advanced-armbased-32bit-mcus-stmicroelectronics.pdf) the ...

How can I connect external ram to stm32h743vit6? I need at least 2 MB of external memory for the display (800x480 16 bit color). SDRAM unfortunately this microcontroller does not support
How do i find an extensive example for read/write value in flash of STM32H7, for store of data to keep after powerloss or reboot? Thanks
