Purpose
The USB CDC Serial Project will help you to get familiar with the USB Device Port(UDP) and USART interface on AT91SAM microcontrollers. Also it
can help you to be familiar with the USB Framework that is used for rapid development of USB-compliant class
drivers such as USB Communication Device class (CDC).
Description
When an EK running this program connected to a host (PC for example), with USB cable, the EK appears as a Seriao COM port for the host, after driver installation with the offered 6119.inf. Then the host
can send or receive data through the port with host software. The data stream from the host is then sent to the EK, and forward to USART port of AT91SAM chips. The USART port of the EK is monitored by the timer and the incoming data will be sent to the host.
