[StanJerm]

hello, where can i download win11 STM virtual com port?  i install both VCP_V1.5.0_Setup_w7_x64_64bits and W8_x86_32bit all not working ! i din see

STM Virtual Com port at device manager! only STM STLink visual com port appear ...

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.

[StanJerm]

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? 

[AScha.3]

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.

[StanJerm]

its data cable...not charger cable i m sure...wats try standard VCP ?  i try this HAL la..

  CDC_Transmit_FS((uint8_t *) charData, strlen(charData));

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.
