E.3 USB
The FZW can be directly connected to a host computer using a USB
cable. The device will appear as a Virtual COM port, which behaves
like an RS232 connection. The required STM32 Virtual COM Port
Driver ( VCP ) device driver for the Windows
TM
operating system is
available from the
MOGL
abs website. After installation, the
FZW
will appear as a COM port.
To determine the port number of the device, go to Device Manager
(Start, then type
Device Manager
into the Search box). You should
see a list of devices including
Ports
(Figure E.2).
Figure E.2:
Screenshot of Device Manager, showing that the FZW can
be communicated with using COM4. The port number might change when
plugging into a different USB port, or after applying a firmware update.
The device can be identified as a COM port with the following name,
STMicroelectronics Virtual COM Port (COMxx)
where
xx
is a number (typically between 4 and 15). In the example
above, the device was installed as COM4.
Note that if the port appears in Device Manager with a different
name, then the driver was not successfully installed. If this occurs,
disconnect the device from the host computer, reinstall the VCP
driver (see below), then reconnect the USB cable.
