Section 2

Getting Started

Build up the RFID reader application system according to the configuration shown on the cover and in

Figure 2-1:

1. Plug the antenna into the socket of the interface board.

2. Connect a serial RS232 cable between the RS232 connector and either COM1 or COM2 of the PC.

3. Connect the supply line from the 12V power source to the jack connector. Alternatively use the

mains SMPS.

2.1 Hardware Settings and Connector Positions

The main board with the AVR®ATmega8515L controls piggiybacked reader interface and maintains the

communication with the host. On delivery the AVR is fleshed with the current firmware and does not

need any special programming or settings. Check that jumper J3 on the antenna interface is in the

default position en.

2.2 Software Installation

The ATAK2270 host installation software as well as the related datasheets and documentation are pro-

vided by the CD-ROM included in the kit. Furthermore, the up-to-date software and documentation are

available via the web.

Execute the setup.exe file found on the CD-ROM to launch the installation and generate the

ATAK2270.exe program file. If the default settings are accepted during installation, the program file will

be installed to path: X:\Programme\ATAK2270\ATAK2270.exe.

Note: Administrator rights are required to install this software.

2.2.1 AVR Programming Guide

The AVR base board (Figure 2-3) is equipped with two programming interfaces, ISP and JTAG allowing

reprogramming or updating the firmware of AVR flash memory.

ISP is a downloading method. Only six I/O lines are needed. The provided header works with the

ATSTK500 as well as the AVR ISP In-System Programmer. Both of these are available from Atmel or

distributors for very low cost program development. To program the flash memory and the EEPROM,

first connect the programming tool to the MB using a six-pin ribbon connector. Make sure that proper ori-

entation is maintained by aligning pin1. The files types accepted use Intel Hex format.

To program a hex file into the target AVR device, select “Program AVR” and then “Connect...” from the

“Tools” menu in AVR Studio. Once AVR Studio has been opened, connect to the STK500 or AVRISP by

selecting “STK500 or AVRISP” in the Platform List. Then select “Connect...”. The driver for the STK500

and AVRISP is then started, and the STK500 dialog should appear. Note that the system supports other

programming platforms as well, like the JTAGICE or the JTAGICE mkII.

Then select the AVR target device from the pull-down menu on the “Program” tab and locate the Intel-

hex file to download. Select the “program” button. Repeat for the EEPROM section.

The same steps apply when using the JTAGICE MKII.

The JTAG Platform allows more control during software development by allowing real-time debugging of

the source code. The JTAGICE MKII supports setting breakpoints and stepping through the code being

executed on the target micro. This is very useful for a more complex software project such as this one.

Fuse Settings:

Fuse bits must be set properly for the kit to function. The only fuse bits that should be set are listed

below.

JTAG Interface Enabled; (JTAGEN = 0)

Serial program downloading (SPI) enabled; (SPIEN = 0)

Boot Flash section size = 512 words Boot start address = $FE00; (BOOTSZ = 11)

Brown-out detection level at VCC = 2.7V; (BODLEVEL = 1)

Int. RC OSC. 8MHz; Start-up time; 6CK + 64 ms; (CKSEL = 0100 SUT = 10)

All others should be unchecked.

Description of the Application Board System

3.1 System Overview

The ATAK2270 application board unit (Figure 2-3) consists of a ready-to-run standard microcontroller

main board equipped with the Atmel AVR®microcontroller ATmega8515L, combined with a piggybacked

antenna interface board containing the U2270B reader IC.

The following functionality is controlled by the AVR microcontroller:

Handling of the bi-directional data communication between the RS232 interface and the host PC

Execution of the read and write commands to be sent to the antenna interface

Decoding of the specific read data delivered by the antenna interface

The source program is written in C, and the compiled hex code is loaded in the 8-kByte Flash of the

microcontroller.

3.2 Power Supply

To operate the reader board, an external power supply in the range of DC 10V to 15V/200 mA has to be

connected to the jack, alternatively use the mains SMPS. A bridge rectifier placed at the connector input

is used for polarity independence.

3.3 Antenna Interface

The antenna interface (Figure 2-2) is supplied and controlled by the main board via header pin X2/1. The

current power supply voltage is indicated by LED1, Power. To adapt a specific antenna coil to the reso-

nant frequency and the Q factor, the components CANT1/CANT2 and R14 (Figure 2-2) can be changed.

For the antenna included in the kit, the parameters are matched as follows:

Resonant frequency: fres = 125 kHz ±1%, adjusted by CANT1/CANT2 with jumper 3 in

position dis

Whole antenna quality factor: Q = 20, adjusted by R14

4871E–RFID–04/08

3.3.1 Frequency Tuning Mode Selection

The reader interface has a built-in frequency tuning feature. By the host software, the resonant fre-

quency of the LC antenna circuit can be switched in four steps. Therefore the board is equipped with two

stages of high-voltage transistor switches to tune the resonator via switched capacitors.

In default setting Tuning Mode is activated, allowing the adjusting of antenna frequency by host menu.

The binary control of the two tuning stages enables the selection of one out of four frequency states.

According to the menu definition the frequency steps are designated as follows:

High Frequency 134.2 kHz (acc. ISO11784/85)

Semi High Frequency 130 kHz

Semi Low Frequency 125 kHz

Low Frequency 121 kHz

In disabled mode, the interface operates with the fixed frequency adjusted typically to 125 kHz.

The currently selected frequency stage is displayed on the application board by the red LEDs Tune 1

and Tune 2 (shown in Figure 2-2, see Table 5-1 for interpretation).

3.3.2 RF Field Control

The status of the RF field controlled by the microcontroller is indicated by the yellow LED RF on.
