VCP for STM32F3

I'm trying to implement Virtual Com Port on STM32F3. I use IAR.

I've included all files from a demo project.

However I have numerous errors while compiling the project. Struggling for hours I came to this question

Is there any compiled project with VCP for STM32F3?

It seems my English is very bad;). Yes, I know what the VCP is.

The working assumption on discovery boards is that they do not have vcp. There are some discovery boards introduced later, I think some of the f4 boards are like that, that do have vcp. Those are St link v2(b?).

Technically only stlink v2-1 boards are capable of vcp.

This may help you get it going:

Again, I think we are confusing a VCP provided by the target chip itself, with the VCP provided by (some versions of) the ST-Link.

We need the OP to clarify the requirement ...

'I need it as a demo project for a user connectivity, not to program/debug with ST-LINK.'

Maybe you are right. Maybe the author of this post needs connectivity through the USB/CDC

I mean directly ti the target MCU.

Just to echo the other poster, if you are looking for a stm32 board with vcp, the nucleo boards are the obeivious way to go, not the discovery boards.

Why not the discovery? I have plenty of Discovery boards with VCP

I think I have to clarify things. I want to connect my PC's USB to USB on a board  and use it as UART terminal.

So select the Discovery or Nucleo model:

Look at price, sensors, displays, arduino connectors (can add extra HW  - arduino shields). All new boards supports VCP - Virtual COM emulated by the ST-LINK programmer / debugger.

Also boards equipped with the second USB port (Some if not all Discovery boards)  can use USB CDC  - direct connection from the MCU to the PC without ST-LINK.

Hi Bogdan,

I perfectly understand that all boards supports VCP. I have no problem with the hardware. The problem I didn't found any compiled VCP  example.

My English too bad? It's hard to understand what I want? I start to panic.
