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...
Hi all,I'm using the STM32L452RET6P in my PCB design.I would like to use its USB Device feature and unlike some other STM32 i encoutered, it seems that here there is a special need in VDDUSB pin on the MCU.Can someone help me understand how to use th...
Hello everyoneI am trying to implement a simple soundcard from using STM32F407G-DISC1 board.It utilizes STM32F407. I am using CubeIDE version 1.10.1I configured the USB to be Full-speed Device Only. And I configured the middleware as Audio class.I se...
Hello, I want to try to use PTP in my project, but the lack of documentation took me into a dead point. I'm currently using an STM32H755 which support the protocol.I have a lot of question but as first thing I want to understand the faesability of th...
Hello,I am programming a USB device from scratch (for learning purposes) on a STM32F7 board.It is a simple HID mouse.Everything works great in the enumeration, my device is correctly recognized by the host (Windows PC) as a mouse. I've chose to use a...
After testing P-NUCLEO-USB002 kit with it's embedded demonstration example I try to use different example from en.STSW-STUSB010 examples- it seems like non of them support UART interface (CLI) as in P-NUCLEO-USB002 embedded demonstration example. my ...

Hello, I find there are a note for 'GP' version LQFP64 package.In blank of UCPD, which has the number "1" .The note is: One port with only one CC Line available(supporting limited number of use cases).Is that mean only one UCPD controller( UCPD1 or U...
We use the STUSB4500 in our design to negotiate with the Host the correct current. In our design we have no connection on the VBUS_VS_DISCH pin. Because of this issue, the PD-Chip does not start negotiation. Is there any way to disable the VBUS_VS_DI...
Hi every body, current we have a problem when make compatible between USB2.0 and type C on our devices.We don't want full type C's feature yet. We just wanted our firmware to be compatible with type C cable on some laptop which have only type C conne...
