Serial Link
The F1LVDemo control GUI operates through a USB to serial interface that appears as
a standard RS-232 serial port to the PC operating system. The USB interface on the
F1 LV Evaluation Platform is an MCP2200 USB to Serial interface device. Ensure that
the drivers for this interface are loaded in the PC before making the connection. Inter-
face drivers can be downloaded for free from the MCP2200 product page of the Micro-
chip web site.
