Several examples are available in ASF that can be downloaded from the Atmel 
website ASF section: 

http://asf.atmel.no

. Each example has the full source code with 

documentation, as well as ready-made binaries for getting started quickly. The 
examples can be compiled using either the GCC or IAR compilers. 

The 

Atmel AT32UC3A3256

 that is mounted on the 

Atmel UC3-A3 Xplained board

 is 

preprogrammed with a USB boot loader and default demonstration firmware. 

The preprogrammed firmware in the 

AT32UC3A3256

 is a demonstration of the Atmel 

QTouch

®

 button and the Atmel QTouch slider. Touching the SW1 QTouch button will 

cause LED1 to light up. Moving a finger along the QTouch slider will cause either 
LED2 or LED3 to light up, depending on the position of the finger. 

The delay at the start of the application is due to an SDRAM check, which is 
performed each time the kit is powered up. This has been removed in the updated 
firmware, described in Section 

6.2

. 

This application note includes a software package that contains the source code of a 
demo application. The demo application demonstrates the QTouch functionality of the 

UC3-A3 Xplained

 board similar to the pre-programmed default firmware but with two 

differences: 

1)  When powered up, the board will not perform the SDRAM check any more 

since this has been removed from the application. 

2)  If the slider is touched, the intensity of LED3 will be adjusted according to the 

touch position on the slider, and LED2 will light up when the slider is touched.
