2 Getting started

2.1 Programming the firmware for the Xplain board

In order to get the QTouch board up and running the AT90USB1287 and

ATxmega128A1 device mounted on the Xplain board needs to be programmed. The

required firmware is included in the .zip file following this application note. For a

detailed description about programming the Xplain board, please refer to application

note AVR1921.

2.2 Connecting the QTouch Xplained

The QTouch Xplained needs to be connected to the Xplain in order to demonstrate

QTouch and the QTouch library features. This section provides all information needed

to connect the QTouch Xplained add-on board to the Xplain mother board, and then

connecting the bundle to the PC host in order to use it with QTouch Studio.

2.2.1 Connecting the QTouch Xplained to Xplain

The QTouch Xplained uses four 10-pin headers to connect to Xplain. This makes it

easy to connect and disconnect the QTouch Xplained from the Xplain board. Note

that the female SMD mounted pin-headers might get damaged if not handled

carefully. The plastic insulation might come off and exposes the conductors. Refer to

Figure 2-1 for an illustration how to connect the two boards together.

• Attach the QTouch Xplained to the Xplain board. The QTouch Xplained is

connected to the Xplain board by connecting the four 10-pin headers on the

QTouch Xplained (female) to the four 10-pin headers on the Xplain (male).

• The text orientation should be the same on both kits.

• Ensure that all four pin headers are properly connected.

2.2.2 Connecting the QTouch Xplained & Xplain to the PC

The Xplain board must be connected to a host PC using an USB cable. The USB

connection is used for communication between the QTouch Studio and the
