Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
Dear STM32 Community, We believe that the example projects provided for the STM32Cube embedded software are a valuable resource when developing projects. We would like to better understand how developers use these examples in their workflow and e...
Hello everyone,I'm working on a project using a NUCLEO-H7S3L8 board, and I have run into a very persistent and unusual problem involving FreeRTOS and a HAL function that I hope the community can provide some insight into.My aim is to build an event-d...
Split from https://community.st.com/t5/stm32-mcus-boards-and-hardware/nucleo-h563zi-as-usb-host/td-p/646056 Hi, I am New here.I was trying to connect the USB Barcode scanner to this Nucleo Board. Did you guys find any solution to make the board act a...
Hey everyone, I'm working on a project where I'm implementing an algorithm on an STM32H7. As part of the algorithm, I need to compute the square root of a matrix using Cholesky decomposition. I noticed that the CMSIS-DSP library includes a function c...
Hi, i have been developing custom bootloader with start address at 0x08000000 and a main application at address 0x08003800 were i planned 14KB for bootloader and next 40kb for main app.i can see the bootloader works fine, but bootloader doesnt trigge...
Hello ST Community,I’m currently developing on the STM32H743 using STM32CubeIDE, with the following configuration:FreeRTOS v1 (CMSIS v1 style tasks)LWIP stack configured in RAW API mode (not using netconn or socket layers)Network communication is up ...
Hello, I'm working on a project using the STM32F401RE board to perform real-time fault diagnosis on machinery.The board receives vibration data in real-time via a USB-type accelerometer (Digiducer 333D01), and a lightweight deep learning model runnin...
Hi, my name is Zaeem Ahmed.I'm currently digging into the STM32F1 HAL and trying to understand it at a deeper level. I'm intentionally not using STM32CubeMX — not because I have anything against it (it’s a great tool) — but because I want to read the...
Hi everyone,I'm working on an STM32H7RS project (NUCLEO-H7S3L8) with the following setup:Bootloader in internal flash (0x08000000)Application in external OSPI flash (XIP) at 0x70000000Using FreeRTOSUsing TIM6 as the HAL time base (not SysTick)Configu...
Hello , I am working with the STM32H755ZI-Q board and configuring it as a USB Host. I’ve successfully tested the USB Host functionality using standard USB devices such as a keyboard and a mouse, both of which are recognized correctly by the host. How...
I am trying to perform USB enumeration on an STM32H503. I am using HAL_PCD_SetupStageCallback inside of the USB interrupt, which is working perfectly: when I plug in the USB cable to the Nucleo board, the interrupt triggers and I can see that the ca...
