DVK90109

DVK90109 125kHz RFID Development Kit User Manual Features and Benefits Standard ISO communications User interface software RS232 serial communication Dedicated instruction set 6 to 9Volts supply compliant Ordering Information Part No. DVK90109 General Description The development kit DVK90109 has been developed by Melexis to create specific applications using 125 kHz protocols and to evaluate the advantages of the MLX90109 transceiver IC. The DVK90109 results of the combination of the development board DVKRFID and the evaluation board EVB90109. The EVB90109 is plugged on the DVKRFID through a 10 pins connector (including Coil, VCC and Ground) and controlled by the microcontroller ATMEGA128. A set of commands has been elaborated by Melexis to define the communication between the Computer and the evaluation board EVB90109. 390129010902 Page 1 of 13 Development Kit Rev. 002 Apr-2008 DVK90109 125kHz RFID Development Kit User Manual Table of Contents 1 UNPACKING THE SYSTEM .....................................................................................3 2 CONNECTING THE SYSTEM ...................................................................................3 3 DIGITAL COMMUNICATION EVB90109 - DVKRFID.................................................4 4 DIGITAL COMMUNICATION DVKRFID PC............................................................5 4.1 Protocol assignment ................................................................................................................ 5 4.2 List of instructions .................................................................................................................. 5 4.3 Error Instruction...................................................................................................................... 6 4.4 Instructions set ........................................................................................................................ 6 4.4.1 Version (VER) ..........................................................................................................................................6 4.4.2 Set Field (STF)..........................................................................................................................................6 4.4.3 Configuration of the MLX90109 (CFG)...................................................................................................7 4.4.4 HEA : HEAder..........................................................................................................................................7 4.4.5 REA : REAd .............................................................................................................................................7 4.4.6 WRI : Write Q5 tag...................................................................................................................................8 4.4.7 SEL : Select tag Hitag1.............................................................................................................................9 4.4.8 RDH : Read Hitag1 memory.....................................................................................................................9 4.4.9 WRH : Write Hitag1 memory...................................................................................................................9 5 MELEXIS RS232 INTERFACE PROGRAM ...............................................................11 5.1 Start RS232 interface:............................................................................................................. 11 5.2 Select serial communication port COM.................................................................................. 11 5.3 Open serial communication port............................................................................................. 11 5.4 Generates commands file ........................................................................................................ 11 5.5 Select commands file .............................................................................................................. 12 5.6 Send a command ..................................................................................................................... 12 6 DISCLAIMER............................................................................................................13 390129010902 Page 2 of 13 Development Kit Rev. 002 Apr-2008
