Interfaces

USB Interface

The USB interface to the board provides a communication port to a host
PC. A USB physical connection is used to enable laptops without RS232
ports to communicate with the demo board.

To simplify the USB interface, the board contains a FTDI FT2232L USB
universal asynchronous receiver/transmitter (UART) circuit. The UART
eliminates the need for full USB software and hardware implementation.
In addition, the USB UART design allows the software to be designed as
if writing directly to the host PC’s COM port, which eliminates the need
for designing a USB software driver (see
