i m implementing my own USB VCP on a USB port (STM32 USB Virtual COM Port (VCP) )

https://medium.com/@pasindusandima/stm32-usb-virtual-com-port-vcp-bc7cb1bd5f5

i m using H734 Nucleo...

Hi,

the VCP driver :

https://www.st.com/en/development-tools/stsw-stm32102.html

should not be needed, as win10 + 11  have driver in system included - so maybe your enumeration going wrong...

or try thr driver - if you want.

yes, thats the website i downloaded, but STM Virtual Com port not appearing at device manager when plug usb cable into H743 Nucleo. Do you hav any idea what went wrong? 

How should i know, what you doing ? (wrong or right...)

So verify you using a data cable,  not a charger cable. :)

Then (which cpu ?) try a standard VCP , using HAL, just to see: it works - or not.

hello... anyone can help ???

 

Look for CDC device example in the Cube example projects for STM32H7, adapt it for your board.

You don't need a VCP driver for late windows 8 forward. It just shows up as a COM port.

If your device isn't showing up, I'd suggest that there is something incorrect with your program running on the H7. You do have a program running on the H7, don't you? You have to provide a program that implements the device side of the VCP, it's not built into the H7.
