USB Virtual COM Port for STM32F4xx devices - http://stm32f4-discovery.com/2014/08/library-24-virtual-com-port-vcp-stm32f4xx/.

With this library, your STM32F4xx will be seen to your computer as Virtual COM Port (VCP). To be able to work, you have to install ST's VCP Driver, from link below:

 http://www.st.com/web/en/catalog/tools/PF257938

This library can work in 2 ways. First and default is Full-Speed mode, second option is High-Speed mode. Also, different modes have different pinouts.

In default settings, USB FS mode is selected.

STM32F4-Discovery has USB connected to FS mode, but STM32F429-Discovery has connected it to USB HS in FS mode. But if you have cable, like me, USB->4wires, you can connect Data+ and Data- to any pin on Discovery board. I did this, to check, if both mdoes work on bots discovery boards and yes, it worked. For security reasons set 22Ohm resistors in serial to your data pins.

USB FS MODE (micro USB connected on STM32F4 Discovery board)

This is default option and don't need any special settings.

Pinout for USB FS mode

USB         STM32F4xx
Data +      PA12
Data -      PA11

USB HS in FS mode (micro USB connected on STM32F429 Discovery board)

If you are working with STM32F429 Discovery board, and you want to use microUSB connector for VCP, then set define below in your defines.h file

//Activate USB HS in FS mode
#define USE_USB_OTG_HS

Pinout for USB HS in FS mode
