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...
I am using the ST Host library version 3.54 on an STM32F769 device, supporting HID devices. I am using the internal Full Speed phys.I have a USB mouse connected and all works fine, however I would like to save power when the mouse is not being used ...
Hello, I wonder that examples could apply Nucleo-H753ZI board... There are some examples about H743 or another one but no example for Nucleo-H753ZI board. I understand 48k-2channel-16bit can be implemented easily, But I wonder that Nucleo-H753ZI c...
Hello everyone,I’m working with the STM32U5G9J-DK2 and trying to implement a Bootloader + XIP (Execute-In-Place) application architecture using the external flash.Target setup:A minimal bootloader running from internal flashThe main application linke...

We are starting to develop a new hardware platform and are currently evaluating the STM32H7R/S series for the main controller.The question now is which RTOS is best suited here in terms of long-term support from ST. We're going to use a lot of commun...
I am using the STM32U585RIT6 microcontroller with the B-U585I-IOT02A development kit. I need to implement USB functionality using an interrupt-based approach. In my project, I have configured USB_OTG_FS in Device-only mode, enabled the NVIC global in...
When using the STM32H743ZI Nucleo board as the I²C master and two STM32 Blue Pill boards as I²C slaves with different addresses, the master requests data from the slaves and the slaves respond accordingly. However, I²C communication is unreliable d...
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...
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...
