5.1 Connecting the Atmel XMEGA-B1 Xplained to USB
When connecting to the USB host computer for the first time, the firmware will
enumerate as a composite device with two USB interfaces.
enumerate as a composite device with two USB interfaces.
The operating system will install the new USB devices by itself (no specific driver is
needed for both mass storage and generic HID interfaces). Once the new hardware
installation process is complete, the XMEGA-B1 Xplained kit is visible in three
different locations within the device manager as shown in the figure below.

5.2 Using the XMEGA-B1 Xplained demonstration firmware
The demonstration firmware can be used in a stand alone mode (meaning without the
PC host application running).

In that case the application displays the selected sensor value using the on-board
LCD glass of the XMEGA-B1 Xplained. The capacitive touch buttons CS0…CS3 can
be used to select which sensor should be displayed.

be used to select which sensor should be displayed.
• CS0 displays the ADC value of the light sensor (raw value of the ADC conversion)
• CS1 displays the temperature value based on the on-board NTC (in °C)
• CS2 displays the potentiometer voltage (in mV)
• CS3 displays the external voltage input (in mV)
