Software Installation
The ATAK2270 host installation software as well as the related datasheets and documentation are provided 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 orientation 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 Intelhex 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.

Section 3 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(R) 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 resonant 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: Whole antenna quality factor: fres = 125 kHz 1%, adjusted by CANT1/CANT2 with jumper 3 in position dis Q = 20, adjusted by R14

3.3.1
Frequency Tuning Mode Selection The reader interface has a built-in frequency tuning feature. By the host software, the resonant frequency 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.
Table 3-1. The Frequency Tuning Can Be Selected Using Jumper J3
Tuning Mode Disabled Enabled Jumper J3 Position 1-2 2-3
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 Semi High Frequency Semi Low Frequency Low Frequency 134.2 kHz (acc. ISO11784/85) 130 kHz 125 kHz 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.

Data Read When a read command is executed by clicking the Read button, the current Read Timing parameters, among others, are sent to the microcontroller baseboard via the RS232 interface. The data stream coming in from the antenna interface is analyzed in real time as specified by the timing definition. Afterwards, the microcontroller transfers the decoded binary values to the host. Default timing settings are suitable for the transponder samples contained in the kit. If a Header Signature is used, ensure that the related Header has already been programmed into the transponder using the Write menu.
Note: When reading a transponder, the specific programmed configuration has to be matched with settings on the host menu, such as Bitrate, Coding, ID-Code Length, and Signature. If the configuration of the transponder is unknown, a reconfiguration is needed.

Selecting Write tab Figure 5-22. ATA5577 Write Tab
In the Extended Mode, the Fast Write check box in the Downlink section is released (This is the only difference to the Write tap in Basic Mode). However the Fast Write feature makes less sense for programming via resonating antenna coupling, due to the needed time duration determined by the gap time of the ON/OFF Keying (OOK). Nevertheless, the feature is performed by the software. It may be worth considering for production programming transponders in Fast Mode by direct coupling or by antennas with low Q factors. If the Fast Write is selected the default values of the Write Timing will be reduced accordingly. In the Write tab, the block data 1-7 and write timing text boxes are automatically populated with their default values. If the Write check boxes are not selected, the blocks will not be written. If the Lock check boxes are selected, the block will be permanently locked. The data for each block is entered in hex. The blocks to be programmed are chosen by selecting the check box in the Write column. To protect the data from being overwritten, select the Lock check box. Once the lock bit is set, the information cannot be overwritten. Use this feature with care. Click the Default button to restore the default settings. To exit the menu, click the Cancel button. The default write timing set should be suitable for typical antenna with Q factors in low to medium range. For special transponders, three ranges of antenna Q factors are selectable. According to Q selection, the required write timing parameters are transferred to the timing window.

The Read menu displays the content of the data blocks 1-7. To read data from an unknown transponder, the configuration of the transponder must be first known and entered in the Bitrate, Coding, MaxBlock and Synchronization fields. The default Read Timing is derived from the Bitrate setting and normally suitable for most transponder applications. The synchronization of the transponder can be configured in the Synchronization area. (Terminator is selected by default.) If Synchronization Bits is chosen, an 8 bit header can be entered. E6h is entered by default in this field. An extended header can be configured by clicking the 12 Bit Header check box and entering the longer header in either the Binary or Hex text field. For an ISO11784/85 transponder, the default header 002h or 003h are needed. Click the Read button to read the transponder block data as specified by the settings. The transponder data is read only once. To read the transponder continually, select the Continuously Read check box. To receive audible notification, select the Sound On check box. This indicates an incorrect or correct reading. To read a specific block from page 0 or page 1, click the Direct Access button. The Direct Access message box is displayed, see Figure 5-24. Select the Page radio button, (Page 0 or Page 1), then select the required block from the drop-down list.
