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...
Hi,I have implemented CDC USB device on my custom board using STM32C071CBT6. When i connect USB cable to host PC then I can see Virtual COM Port on PC as 'USB Serial Device (COMxx)' However, I tried transmitting some data which I could not receive on...
Hi everyone! I’ve been diving into the AXI4 protocol for a small design exercise, and while I’m making progress, I’m still trying to build a solid intuition for the VALID/READY handshake, especially on the less 'visible' channels like the Write Respo...

I would like to use the single USB internal PHY on the STM32H735 to connect to a 2 port hub chip (like the Microchip USB2422) so that I can connect to both a USB stick for firmware upgrades as well as a cellular module. I started connecting everythi...
I've seen that, trying to download the STM32CubeH7RS Firmware Package from CubeMX, I'm seeing the latest version is 1.3.0.On the actual documentation and GitHub repository https://github.com/STMicroelectronics/stm32h7rsxx-hal-driver I'm seeing that t...
Hello,I am trying to get the audio data from ADF1. Therefore I use the GPDMA as shown in this example: https://github.com/STMicroelectronics/STM32CubeU5/tree/main/Projects/STM32U575I-EV/Examples/MDF/ADF_AudioRecorder. I am developing on a B-U585I-IOT...
Hello guys,I am using Ethernet and USB together. Ethernet in rmii mode without RTOS and Using USB as cdc,after flashing the program it runs normally but when i ping or Access the IP from web :spider_web: it goes to hard fault handler If USB init ...
Hello,I am currently working on a project with an HTTP server, successfully implemented using FreeRTOS. In this setup, I handle client requests for opening and collecting data from the client side. However, since I need to display real-time data on a...
Dear allI am relatively new to STM32, using STM32H563 as an SPI slave to receive data and send some feedback data as same time, The SPI master is a Tiva MCU form Ti, as data is relatively long, I need to use DMA, I tried to find an example for it, b...
I am migrating from STM32L431 to STM32L471. After migration, the function relating to internal flash writing does not work any more. The problem is when I programmed internal flash with HAL_FLASH_Program(FLASH_TYPEPROGRAM_DOUBLEWORD, address, data), ...
