1 Introduction

The Atmel AVR XMEGA

®

-A3BU Xplained evaluation kit is a hardware platform to evaluate the Atmel ATxmega256A3BU microcontroller.

The kit offers a larger range of features that enables the Atmel AVR XMEGA user to get started using XMEGA peripherals right away and understand how to integrate the XMEGA device in their own design.

3 Quick-start

8324B-AVR-09/11

Atmel AVR1935

To be able to run the preprogrammed code, you need to connect the Atmel AVR

XMEGA-A3BU Xplained evaluation kit with a USB cable (standard A to mini-B or mini

AB) to a PC or USB hub. Once the kit is powered it is possible to browse the menu system with the on-board mechanical buttons and the touch button. The functions for the buttons are:

• Top left mechanical button (SW0): Enter a menu

• Bottom left touch button (QTB0): Return from a menu

• Top right mechanical button (SW1): Browse the menu up

• Bottom right mechanical button (SW2): Browse the menu down

The demo application allows also the XMEGA-A3BU Xplained board to communicate with a computer using USB with a CDC (Communications Device Class) setup, allowing the keyboard to be used to navigate in the demo application. When the

XMEGA-A3BU Xplained board is connected for the first time, Windows will try to install a driver for “Virtual CDC Com”. A driver file, XPLAINED_Virtual_Com_Port.inf, is located in the demo application directory or can be downloaded from the Atmel web-site ( Xplained USB CDC driver download ). If the driver is successfully installed, the board will show up in the Device Manager under Ports (XPLAINED Virtual Com

Port (COM**)). This COM port can now be interfaced with your favorite terminal software. The connection parameters are as follows:

• Baud rate: 115200 baud

• Data bits: 8

• Stop bits: 1

• Flow control: None

If the connection has been successfully established, you should be greeted by this text on the screen of your terminal:

Welcome to the XMEGA-A3BU Xplained Demo CDC interface!

Key bindings for LCD menu control:

Enter : Enter

Backspace : Back

Arrow Up : Up Arrow

Arrow Down : Down Arrow

The demo application for the XMEGA-A3BU Xplained is available through the Atmel

AVR Software Framework (ASF), version 2.6.0 or later. The demo application is available as an example project in AVR Studio

®

5 and can be accessed by clicking

File -> New -> Example Project, and selecting “Demo application for XMEGA-A3BU

Xplained”. In-depth documentation for the demo application is available in the

XMEGA-A3BU Xplained Software User Guide.

To modify the example code or write new code and compile it, you need a toolchain for the Atmel AVR microcontrollers and an IDE to edit and debug code. Atmel provides both with Studio 5. More information about all available documentation and tools is available in the chapter

5

.

3.1 Programming the kit

3.2 Using the bootloader

The kit can be programmed either from an external programming tool or through a

USB bootloader which is pre-programmed on the device. The bootloader is evoked by pushing the push button (SW0) during power-on, for example. push and hold the button and hence connect an USB cable to the kit. Programming can be performed through the DFU programmer FLIP. How to use FLIP to download new firmware to the kit is described in-depth in the application note AVR1929: USB DFU Bootloader for XMEGA A3.

3.3 Using a programming tool

If it is desired to program the kit without the help of the on-chip bootloader, or if debugging is required, it is possible to do this with various tools. The most common

tools and how they can be connected are listed in chapter 4 . Atmel AVR Studio 5 can

be used as front-end for these programming tools.

NOTE Because JTAG TDO and PDI DATA are connected on the PCB for this kit, JTAG must be disabled on the device in order to use PDI. JTAG can be disabled by programming the JTAGEN fuse of the device.

4 Connecting the kit

4.1 USB power supply

Connect a USB cable between the board and a PC or a USB power supply to power the kit. This is all that is needed. When power is applied the power/status LED will light up in green.

Do not power the board without having the jumper next to the USB connector or an amperemeter mounted. Otherwise, the device may be damaged.

When connecting the Atmel XMEGA-A3BU Xplained 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

32-bit and 64-bit versions of Windows

®

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

®

operating systems.

4.2 Atmel JTAGICE3

Figure 4-1. The 100mil JTAG adapter must be used to connect to the kit.

4.3 Atmel AVR ONE!

The AVR ONE! JTAG connector can be connected to the XMEGA-A3BU Xplained kit with a standoff adapter (adapter is marked with "nr.1").

4.4 Atmel AVR JTAGICE mkll

The grey female 10-pin header on JTAGICE mkII has to be used when connecting to the kit. The opening in the board is made to fit the orientation tab on the header.

NOTE When using PDI with the JTAGICE mkII it is necessary to use the squid cable. Follow the instructions in the JTAGICE mkII manual and the silkscreen description for the programming header.

4.5 Atmel AVR Dragon

®

In order to connect the AVR Dragon to the XMEGA-A3BU Xplained, a 10-pin header cable is needed. Connect the cable between the JTAG connector on the AVR

Dragon™ kit and the XMEGA-A3BU Xplained JTAG connector. Pin 1 on the XMEGA-

A3BU Xplained kit is marked with a square pad.
