Overview:
This example shows how to use the USB driver to implement a CDC class USB peripheral.
To run this example, you must attach a USB cable to the board. See
the "Getting Started Guide" appendix for details.
How to use:
Click the debug toolbar button.
Click the go button.
Plug the LPCXpresso's target side into a PC using a USB cable retrofit
or a 3rd party base board.
* You should be able to see a new COM port on your PC.
