It addresses a wide range of applications such as industrial or medical equipment and consumer electronics. This kit contains 2 different boards, as shown in the figure on cover page. The M24LR board is battery-less and is powered by RFID readers or NFC-enabled phones supporting ISO/IEC 15693. The RF transceiver board is an RFID reader demonstration board and is composed, among other parts, of a CR95HF (13.56 MHz multi-protocol contactless transceiver IC with SPI and UART serial access). This board has to be plugged in to a PC and comes with a demonstration software. The M24LR board also works with Android NFC phones supporting ISO/IEC 15693. An application called NfcV-Reader is available on Google Play. Performance may vary depending on NFC phone's RF management. System requirements 1.1 • Windows® PC (2000, XP, Vista, 7) • ISO/IEC 15693 capable NFC phones Demonstration software The M24LRxx application software can be uploaded from www.st.com and installed on your PC. It consists in: 1.1.1 • an M24LR/CR95 application software setup file [STSW-M24LR011] • an STM8L firmware, see STM8L firmware M24LRxx application software The PC software allows to: 1. Launch setup.exe executable. 2. Choose CR95HF DEMO KIT tab. 3. Select demo NDEF messages tab. 4. Click on demo NDEF & Energy Harvesting tab. The latest versions of this demonstration source code and associated documentation can be downloaded from www.st.com. 1.1.2 STM8L firmware Development toolchain In case of an STM8L firmware change, the user has to download: • 2/5 STMicroelectronics, ST Visual Develop (STVD) DocID023090 Rev 3 M24LR-DISCOVERY Description STM8L firmware Demonstration software is preloaded in the board's Flash memory. This demonstration displays on the LCD: 1.2 • The text messages stored in the M24LR04E-R Dual Interface EEPROM • The internal voltage of the M24LR board • The ambient temperature measured from the sensor Android application Install the NfcV-Reader applet available from Google Play. This application enables the NFC communication (Settings-Wireless & Networks-NFC) for evaluation on an Android device. 1. Download the NfcV-Reader App from Google Play and install it on the Android device. 2. Launch the NfcV-Reader application. 3. Place the device's NFC antenna close to the M24LR board antenna. The NFC phone powers the M24LR board. The text message can be changed using the NFC phone (select NDEF function and select write NDEF message menu). Performance may vary depending on NFC phone's RF management. DocID023090 Rev 3 3/5 5 Revision history 2 M24LR-DISCOVERY Revision history Table 1.
