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’m working on an STM32H7R7 project using SDMMC1 + FreeRTOS (CMSIS-RTOS v2) + FatFs, all generated with STM32CubeMX.I’m facing an issue where f_mount(opt=0) works, but the system blocks inside f_open() and never returns, so the return value cannot be...
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...
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 ...
Hi everyone,I’m working with an STM32L5 USART and trying to clarify a point about parity vs. MSB-first transmission.From the reference manual (USART parity control / frame formats), when parity is enabled the frame formats are shown as:M=00, PCE=1: S...
I'm reading RM0492 Rev 3 about I2C's controller transmitter. The original words on the page of 1185 areWhen RELOAD = 0 and the number of data bytes defined in NBYTES[7:0] is transferred: • In automatic end mode (AUTOEND = 1), a STOP condition is auto...
Hello,I am using STM32H750VBT6 to perform microSD card write operations. After a number of writes, the CPU sometimes resets during a write operation. At the same time, the Vcore (1.13V) rail shows a voltage drop. The issue is random, but the higher t...
Dear STM32 users and developers, This new thread is back and is dedicated for our technical developers community to share last STM32 updates, the first part will be products documentation news such as datasheets, Erratas, Applications notes followed...
Hello everyone,I’m working on a control unit board based on the STM32F407VETx (LQFP100) microcontroller. During development I noticed that some pins configured as external interrupts (rising edge) were being triggered more often than expected.To bett...
