Introduction

1

1. IntroductionThe xmega.Dip is a breakout board for the ATxmega A4U Microcontroller with fully wiredMicro-USB connector which serves as power supply.

All available pins of the xmega microprocessor are accessible and the operating voltagecan be changed from 3.3V (default) to 1.8V for ultra low power mode.

The Atmel DFU bootloader is already installed so that you can easily flash your softwarevia USB.

Scope

2. ScopeThis document describes the characteristics of the taskit xmega.Dip board, lists themost important key features of the ATxmega microcontroller and gives some hints fordevelopment.

The ATxmega microcontroller with the AVR core itself is descriped in deep in the Atmeldocumentation which is available on the Atmel webpage: Atmel AVR XMEGA AU ManualManual [http://www.atmel.com/products/microcontrollers/avr/AVR_XMEGA.aspx].

4.3. Power supply voltage selection

The supply voltage of the ATxmega microprocessor can be changed in order to activatethe most efficient power saving modes. This is done by moving the 0-Ohm resistor.

Figure 4.3. Power supply voltage selection

4.4. Operating temperature

-30 °C to +85 °C

4.5. Dimensions

Usage

8

5. UsageTo write, compile, debug and install applications for the xmega.Dip we recommend usingthe Atmel Studio 6 or higher together with the Atmel AVR Dragon board and the Windowsapplication FLIP from Atmel.

5.1. Development

The Atmel Studio 6 [http://www.atmel.com/microsite/atmel_studio6/default.aspx] is freeof charge (only registration required) and can be downloaded on the Atmel website. Itcontains the ASF to insert ready to use drivers (inclusive QuickStartGuide) for componentslike clock, timers, USB (HID, CDC, MSC).

ASF - Atmel Software Framework

ASF is only available after creating a project with an AtmelBoard or UserBoard.

5.2. Debugging

With the Atmel Studio 6 and the Atmel AVR Dragon board [http://www.atmel.com/tools/AVRDRAGON.aspx] it is possible to flash and debug the currently developed applicationon the xmega.Dip.

Connect the AVR Dragon board to the USB port and it will be recognized by the AtmelStudio and you should update it there first (Tools->AVR Firmware Tools Update).

Connect the xmega.Dip to USB (power supply) and to the ISP interface of the AVR Dragonboard. Then you can select interface PDI (Project->Project Properties->Tool)

Figure 5.1. Debugging

5.3. Flashing

The Atmel DFU bootlader FLIP [http://www.atmel.com/tools/FLIP.aspx] is already pre-installed so that the xmega.Dip can be programmed immediately via USB with the desiredapplication. To do that do the following:

1. Start Flip

2. Click on "Select->Device" and shooce the correct device from the list

3. Press the PGM button on the xmega.Dip or short circuit PC3 with GND

Usage

9

4. Press the Reset button or short circuit RST with GND and release it or remove powersupply for a second

5. Press CTRL+U and click on "Open" -> the signature bytes should be displayed in FLIP

6. Press CTRL+L and select the HEX file to programm

7. Click on the "Run" button (bottom left) and the device should be programmed withinseconds

Atmel FLIP

FLIP version 3.4.5 or higher is required in order to use FLIP with xmega boards.

When FLIP is installed, the installation folder contains the driver (.inf)for windows, which is requested when the board is started in DFU(Device Firmware Upgrade: Atmel AVR1916) mode (see section "Flashing")to install applications. [http://www.atmel.com/products/microcontrollers/avr/avr_xmega.aspx?tab=documents]

5.4. Reinstallation of USB DFU bootloader

During development with the Atmel Studio 6 the bootloader may be deleted. In this caseinstall it again when the development is finished again:

1. In the Atmel Studio select "Tools->"Device Programming"

2. Select the used board and interface ("AVR Dragon" and "PDI") and click Apply

3. Connect the xmega.Dip board via PDI and supply power to it

4. Click in "Device signature - Read" -> the device signature should be displayed

5. Click on Memories on the left

6. In the "Flash" panel select the Atmel DFU bootloader file (At least version 1.03:AVR1916.zip [http://www.atmel.com/products/microcontrollers/avr/avr_xmega.aspx?tab=documents])

7. Click on "Programm"
