Introduction
This article is a step-by-step guide on how to implement an STM32 application as a USB device. This device should combine human interface device (HID) and device firmware upgrade (DFU) functionalities into a composite USB device. This al...
Introduction
VCONN is a dedicated power supply pin in the USB Type-C® connector. It provides power to the cables electronics, such as e-markers (EMC), long cables with data repeaters, and VCONN-powered USB devices. It ensures proper power supply ...
Introduction
The USB Type-C® and USB PD specifications revolutionized device connectivity by merging data transfer and power delivery for up to 240 W (with EPR in USB PD 3.1). A key feature, fast role swap (FRS), allows a power supplying device quic...
While the STLINK-V3 is compliant with USB 2.0 and exhibits reliable USB performance across various platforms since several years, the USB communication may fail between an STLINK-V3 and some recent computers.

The root cause comes from...
Introduction
The article provides a comprehensive guide on selecting suitable endpoints for USB applications using STM32 microcontrollers. This involves understanding the types of data transfers required by the application and determining suitable en...
Hi @danielspronk9
I guess STEVAL-2STPD01 manages only USB power delivery negotiation. I would suggest using STM32H7RS for power delivery negotiation and data communication concurrently.
Hi @PPate.1
The compilation errors are caused by the missing driver files. Ensure your CubeIDE properly includes drivers and middleware files.The connector used can have a crucial impact on the enumeration phase. It’s also recommended to use properl...
Hi @RJain.1
Only STMicroelectronics COM ports are authorized.
In your specific case of a USB UART converter that appears as a COM port to the PC, it is excluded from the list of potential COM ports by the STM32CubeMonitor-UCPD. Otherwise, any compet...
