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....
ST‑LINK Mini V3E not detecting STM32H7 (Core ID error, high current when VTARGET connected)I’m debugging an issue with a custom STM32H7 board and an ST‑LINK Mini V3E. The setup includes a main PCB and a separate power PCB. So far:Power & Basic Checks...
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...
Hi everyone,I'm working with an STM32F401CCU6 and trying to transmit 2 bytes over I2C3 using DMA1 Stream 5 Channel 6, which is the correct mapping according to RM0368 Table 28:DMA1 Channel 6 Stream 5 -> I2C3_TXThe DMA configuration appears correct, a...
Hello,I have a issue with my STM32U5G9. It does not go into standby or shutdown mode. I want to achieve a wake-up by the power button of my device. The powerbutton is connected to PWR_WKUP6 (pin PB5). The button has a 100k pull-up. I verified the vol...
Hello!I am writing a program for STM32F769I-DISCO board that uses FreeRTOS and LwIP to communicate with the server and send data to it. It generally works, but unplugging and plugging Ethernet cable (especially doing it several times within a few sec...
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...
