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 guys i have a nucleo h7A3Zi-q dev board . i am trying to receive CAN messges sent from ESP32 borads . esp is sending can frame by using SN65HVD232D. and i configured the FDCAN to receive the can messages . esp can is set at 500 kbits , and my stm...
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 There,So, I got some of the STM32C011J6 MCUs for my simple project of reading sensors data and generating an interrupt.But I am in a dilemma, that the MCU's has I2C Pins, SWD Pins for programming, GPIO pins to act as interrupt but how to initializ...
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 ...
I am having a custom board having STM32N657I0H3Q interfaced with quad flash MX25R6435FM2IL0. I am unable to access (both read and write) to the flash MX25R6435FM2IL0.I have attached Saleae capture (configured the flash in single mode only for Saleae ...
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 ...
Hello,I'm using the STM32H723 (at 550MHz) to generate pulses on a GPIO output at a certain frequency (around 4KHz)I'm generating the pulses with assembly code. I've stopped systick and interrupts. However, looking at the signal with a scope, I'm disc...
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...
