The main user interface offered by the kit is the touch user interface consisting of the wheel sensor and the five button sensors. The touch sensors are implemented by using the QMatrix method (X=6, Y=2). The CAT IP of the AT32UC3L064 is used, as is the ACIFB IP (implied by the use of the QMatrix method). Applications running on the AT32UC3L064 need to use the QTouch library for optimal touch events management.
Four general purpose LEDs (labeled LED0, LED1, LED2, and LED3) are connected to the AT32UC3L064.
The WAKE pushbutton can be used as a general purpose pushbutton, and is connected to the special purpose WAKE_N pin.
The RST pushbutton is used to generate an external reset to the AT32UC3L064. A three-axis accelerometer is connected to three channels of the AT32UC3L064's ADCIFB IP.
