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.

Board overview Figure 2-1 shows most of the available features on the board. For more detailed information on the Atmel XMEGA-A3BU Xplained hardware, take a look at the Atmel application note “AVR1923: XMEGA-A3BU Xplained Hardware User’s Guide”. Figure 2-1. Overview of the Atmel AVR XMEGA-A3BU Xplained kit.

Atmel AVR1935 3 Quick-start 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.

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.

Atmel AVR1935 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.

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. Figure 4-3.
