It seems that using the comparators with interrupts on the stm32f373 series with HAL drivers blocks the program in infinite loop.
I attach the full code as a file and the relevant part here - for the evaluation board STM32373C-EVAL in which the red LED blinks a few times until the comparator is activated and blocks the execution.Is there a workaround to make the comparator work...
Empty check flag on STM32F030 (option bytes)
Hello,I have a problem when flashing my MCU (STM32F030CCT).After flashing, a Power On reset is always needed to start my SW (to reload the option bytes due to the "empty check flag").From manual: On STM32F070x6 and STM32F030xC devices only, internal ...
RM0440 Rev. 2: Number of significant bits in FLASH_WRPxxR apparently wrong.
RM says for both Cat. 2 and Cat. 3 devices all WRPxxR have 7 significant bits, and production values for option bytes starting at 0x1FFF7818 are 0xFF*0*0FFFF.This suggests that bit 7 in WRP_xxR reads '0''.However, actual G431RB has only 6 significant...

Resolved! STM32F030RCT6 and STM32F030CCT6 don't reset after being programmed from blank flash.
Hi guys, We have 2 different boards with STM32F0 processors, STM32F030RCT6 and STM32F030CCT6. Both boards work well, we are able to program, reset, run the code etc. However there is 1 conditions that leave the board in a unknown state and it's repro...
ADC self calibration, needed or not ?
Hello,I have a project where my ADC channels will be calibrated end of line using a calibration bench. I will directly calibrate the physical measurements (voltage and current). My question is: do I need to implement the ADC self-calibration sequence...
Resolved! How to set ADC SOC at half of duty cycle Ton?
Hi,I'm designing a power supply using a stm32F334R8 Nucleo board. For the application is interesting to trigger the ADC SOC at half the Ton (In order to measure average current).I am using STM32CubeIde. I have read the reference manual and the HRTIM ...
Why FMC bus turnaround time is so long in mode D on STM32F303?
I'm using STM32F303ZE MCU's FMC(FSMC) to communicate with a special chip. FMC is cofigured in NOR/PSRAM mode, asynchronous, non multiplexed, timing mode D (see attached FMC configuration in CubeMX). FMC clock is equal to AHB MCU clock that is 70MHz. ...
LPUART does not work
Helloi am using STM32 NECLEO-L010RB here i use low power uart (LPUART) so i try to send string on the terminal but i get garbage on the terminal so please provide me some example code.Thanks.
