Dear all, i have a problem with my custom board based on STM32H745.I need to use core M4 with USB_HS host with mass storage class (a pen drive) at 12Mbit full speed (internal Phy transceiver).I have configured the processor as per attached file (core...
Hi everyone,I am using a STM32H563RG and I need the RTC to work even if the VDD is powered off. To do that, I am plugging a battery on the VBAT pin to power the RTC and the Backup domain. But I tested it and it seems the RTC is stopped and the backup...
We are using the STM32U5 MCU and its internal RTC in our project.We are facing an issue where the RTC time sometimes goes beyond 24 hours — for example, we observed a timestamp showing 37 hours. The RTC is configured in 24-hour format, and we have in...
Hello, I try to get data from a X-NUCLEO-53L8-A1 board connected to a Nucleo board and visualize it in my computer. If I use the VL53L8CX Gui and connect my COM port and click on the start button, it is working well. However, I would like to get dat...
I am using STM32 Nucleo-l476rg. I am trying to use the CAN peripheral and have tried every resource I came across. I am unable to send or receive messages:I have no filter, everything is wired correctly, what could be the issue? I even made it so tha...
I’m working on an STM32H7R7 project using SDMMC1 + FreeRTOS (CMSIS-RTOS v2) + FatFs, all generated with STM32CubeMX.I’m facing an issue where the system blocks inside f_open() and never returns, so the return value cannot be checked.A key aspect of t...
CNC material affects EMI, thermal dissipation, and grounding.I found this CNC material selection guide helpful:https://www.justway.com/blog/CNC_Machining/How_to_Choose_the_Perfect_Material_for_CNC_Machining_A_Comprehensive_Guide_fb9e953e.htmlHow do y...
Content:Hi,I am using UART on STM32G4 in interrupt mode (RXNEIE + NVIC enabled). I observed the following situation: 1. A byte is received → RXNE = 1 2. At that moment, UART interrupt is disabled (critical section) 3. Later I re-enable the UART inte...
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...
I am attempting to reconfigure Pin 8 (datasheet default assignments are PB6/PA14-BOOT0/PC15-OSCX_OUT) from PA14-BOOT0 to PB6 GPIO Output Open Drain (GPIO_MODE_OUTPUT_OD) a short time after start-up.My current attempt (code below) does not accomplish ...
