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.

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 @DmitryR
Indeed, the function calls might differ from those generated on my target. This discrepancy could be due to the fact that some lines were released at different times. Additionally, STM32U5 uses the USBX native library, whereas H7 relies ...
Hi @Schenna10
Any 5V tolerant pin with external interrupt functionality can be used with an external resistor divider, to fulfill AMR conditions. In this case, the recommended values are 2x100 kOhms.
The software needs to handle VBUS presence events...
Hi @petertan
Yes, it's one of the reasons, we reduced TCPC support because we had internal UCPD in the STM32. AFAIK, FUSB30x doesn't refresh to support latest PD releases. Also, because of responsiveness and speed of I2C, we cannot have more than 3 ...
