1 Introduction

The Atmel

®

UC3-A3 Xplained evaluation kit is a hardware platform for evaluating the Atmel AT32UC3A3256 microcontroller .

The kit offers a range of features that enable Atmel AVR

®

UC3 users to get started using UC3 peripherals right away and understand how to integrate the UC3 device in their own design. This getting started guide will take you through all the basic steps needed to start using the UC3-A3 Xplained evaluation kit .

Application Note

Figure 1-1. UC3-A3 Xplained evaluation kit.

Rev. 32163A-AVR-03/11

2 What is needed to get started?

To be able to run the preprogrammed code, you need the Atmel UC3-A3 Xplained evaluation kit and a USB cable (Standard-A to Mini-B or Mini-AB) to connect the board to a PC.

When connecting the UC3-A3 Xplained board to a PC, the operating system will request a driver file for installing the serial communication driver. This driver file is available in the zip file associated with this document. The driver file supports both the 32- and the 64-bit versions of Windows

®

XP and Windows 7. Driver installs are not necessary on Linux

®

operating systems.

To modify the example code or to write new code and compile it, you need a toolchain for the Atmel AVR microcontrollers and an integrated development environment (IDE) to edit and debug the code. Atmel provides both Atmel AVR

Studio

®

4 and Atmel AVR32 GNU Toolchain . Other IDEs and toolchains are also available, such as IAR Embedded Workbench

®

.

If you also want to debug the code at runtime, debuggers like the Atmel AVR

JTAGICE mkII or the Atmel AVR ONE!

are needed. More information about these tools is available from the Atmel website.

5 Programming the kit

5.1 Programming via the boot loader

The boot loader is evoked by pushing the physical push button (SW0) during powerup; that is, push the button, and then connect a USB cable to the kit. Programming can be performed by using the BatchISP command line tool, which is part of the FLIP installation. BatchISP can also run under Atmel AVR32 Studio , which has a GUI interface.

Once the boot loader is active, it will appear as a USB DFU class device, and

Windows will ask for a driver. The driver can be found under the FLIP installation directory.

Figure 5-1. The AVR32 Studio AVR Targets menu.

To program a new firmware, right-click on the UC3A3 DFU target in the AVR Targets section of AVR32 Studio (see Figure 5-1 ), and then select “Program…” from the menu (see Figure 5-2 ).

The following window will appear on the screen:

Figure 5-3. The DFU boot loader file select and programming options.

Browse and select the .hex file, set up the options as shown here, and click OK. A small progress bar will appear in the lower right corner to indicate that programming is ongoing. When the progress bar stops and disappears, the programming is done, and the application will start automatically.

5.2 Restoring the boot loader

If the boot loader has been overwritten or erased, for example by performing a chip erase command, the boot loader can be reprogrammed by using one of the programmer tools described in Section 2.6, Programmers and debuggers .

5.2.1 Reprogramming the boot loader via Atmel AVR32 Studio

To reprogram the boot loader, right-click on the target to use in the AVR32 Studio

AVR Targets window, as shown in Figure 5-4 , and select “Program Bootloader” from the context menu.

6 Example applications

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.

6.1 Preprogrammed firmware

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

.

6.2 Updated default firmware

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.
