Greetings!I have the following system:STM32U073CCVBAT pin is connected to a super-cap, and it's voltage was measured to be above the required minimum.During system reset (NRST) it behaves according to my expectations, the RCC_BDCR remains unchanged, ...
Hi, I am using the STM32H755ZIT6 dual-core microcontroller.The internal Flash memory has a sector size of 128 KB and a page size of 4 KB. In my application, I perform erase and write operations on a specific Flash sector. If a power failure occurs wh...
Hi everyone!Could someone help me to understand a problem with STM32G070.We have deployed approx. 50-60 devices with stm32g070 MCU that saves some parameters in FLASH every 24 hours. I know that according to datasheet FLASH memory endurance for this ...
Hi, I'm currently working on a project with an H755 board.The project uses UART communication. I'm developing it on a Windows 11 computer, and it generally works fine on that computer. So far, there are no issues.However, after completing the project...
1.AN5959 for STM32H523 has a note PB8/PB9 Not available for LQFP48, UFQFN48, WLCSP39.LQFP64 is not mentioned there but it has only PB8 pin and no PB9 pin. That makes it unusable by boot loader. So why it is not included in the note?My question is if ...
Hi,Few days ago i've encountered a strange behavior of the comparator at STM32G4. I investigated the problem under controlled conditions (used Nuclo kit instead application PCB) and the result is startling.Comparator 4 configured to get positive inpu...
Hi all,I am working on firmware that involves SPI communication using a Nucleo board (Nucleo-L4R5ZI-P) with an STM32L4ZIT6 microcontroller.I am trying to establish communication with an SPI slave device. The chip select (NSS) signal is expected to be...
Hi,I am unable to flash or erase two of my STM32G030F6P6 boards. The issue started after I tried to configure the PA14 pin as GPIO_EXTI14 in CubeMX. (on two boards)After flashing the binary I was not able flash the MCU anymore. I get the error "Error...
Hi, I am trying to reset HRTIM on an external event using TIM1 TRGO as a reset event. I am trying to make a single pulse every 200ms (5Hz) because I want to make a single puls test. However, I also need a high resolution so I can vary the on time and...
In RM0316 rev.10, in Table 109. COMP register map and reset values, bit 1 of COMP2_CSR is marked COMP2_INP_DAC, whereas the STM32F303 are not supposed to have this bit (only STM32F301/302x6/8 do) - probably a copy/paste artefact/relict.Can ST please ...
