Virtual Communications Port
The F3 Femto utilises the STM32 Virtual Com Port (VCP). This allows the UARTs on board to be utilised whilst the USB is connected. This
requires the STM VCP driver to be installed in order for the VCP to be recognised.
The STM32 VCP driver can be downloaded here --> http://www.st.com/web/en/catalog/tools/PF257938
NOTE: Once you download and run the installation it has not installed the driver, merely unpacked the choice of drivers. Locate the
installation directory and then run the EXE file pertaining to your system.
e.g. C:\Program Files (x86)\STMicroelectronics\Software\Virtual comport driver\Win8\ <- will have two files present. One for 64 bit systems
and one for 32 bit systems.
