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...
When using USB CDC to communicate via USART, and interacting with USART data, in code is it recommended to interact with it at the USB side, or to interact with it at the USART side?From what I can tell, both offer both polling and interrupt methods....
From what i've seen the Rust programming language is becoming more and more popular and since it does not rely on a virtual machine, like java or python, it could be a good option for embedded development and other low-level programs. I know that the...
Post Edited by ST moderator to apply source code formatting Hi ST Community,I am using STm32U575VGTX. I configure RTC as default, enable RTC non-secure interrupt, activate alarm A trigger each 10 seconds as below: *******************************...
Hello,in our application, running on a H533RET6 and with no TZ enabled, we need to close debug ports in production.I preliminarly did some tests using CubeProgrammer: I generated password-based credentials (obk+bin files, which as far as I understand...
I'm trying to enable USART transmission (TX only for now) via DMA, but when I call HAL_UART_Transmit_DMA, the transfer doesn't seem to start at all and HAL_UART_TxCpltCallback is never called.I've configured everything through CubeMX: enabled USART w...
Hello,I am implementing a USB Audio Class 1.0 microphone on an STM32 (Full-Speed only).The device enumerates correctly on Windows and appears as a 4-channel microphone in the Sound Control Panel, but no WASAPI-based application can open the input str...
Hello ST Team, I developed a custom USB DFU HOST class on an STM32F446ZE. I soldered a USB-C cable directly to the D+/D-, 5V and GND pins. The Problem: The stack works correctly for transfers up to 128 bytes. However, when I set phost->Control.setu...
Hello everyone, I'm having some trouble implementing I3C communication and would like to ask for some help. I am using the NUCLEO-H503RB board as my main controller. For the target devices, I have the NUCLEO-IKS01A3 expansion board and the TSC1641 (C...
helloDescription:I'm currently working with the STM32U585 and encountered an issue related to USART3Most of the time the code works fine, but it occasionally gets trapped in HAL_UART_IRQHandlerI am using the DMA Receiver Timeout (RTO) and DMA TX, may...
I want to make a pedometer app that would count steps and display the number of steps on an LCD screen. I have tested my functions for the screen (ILI9341 SPI), and they work successfully. I tested the LCD code by initializing a timer that incremente...
