5.2.2 Using the USB generic HID interface
This USB interface offers the capability to control and get the following information
from the Atmel XMEGA-B1 Xplained:
• Retrieve on-board sensors measurements
• Get touch buttons status
• Get information about the connected firmware
• Adjust on-board LCD contrast and backlight level
• Control on-board LEDs
• Display user input text strings or numeric values on the LCD
The generic HID interface is accessible using the PC host application previously
installed. Once the application is started it displays a control panel with the same look
and feel as the XMEGA-B1 Xplained kit:

When connection with the XMEGA-B1 Xplained kit is successful, the application
displays some information related to the firmware (firmware revision, version of silicon
the firmware was built for, and ATxmega128B1 Silicon revision) as shown in Figure
