This document describes a software and hardware RFID interface using the STR71x I2C peripheral and the CRX14 RFID transceiver. The main purpose of this software and hardware package is to provide resources to assist the development of an application using an RFID tag. The software interface is composed of library source files, include files and some application template source files.
This document describes a software and hardware RFID interface using the STR71x PC peripheral and the CRX14 RFID transceiver. The main purpose of this software and hardware package is to provide resources to assist the development of an application using an RFID tag. The software interface is composed of library source files, include files and some application template source files.
The note covers the file organization of the RFID library, an overview of radio frequency identification, operating ranges and applications, ISO standards, ST short-range contactless memories (SR176, SRIX4K, SRIX512), the ST short range coupler CRX14, and an overview of an RFID reader using STR710.
The main purpose is to provide resources to assist in developing an application using an RFID tag.
Close-coupling ranges include distances up to 5 cm between the transponder and the reader.
These applications operate in a range up to 20 cm from the reader.
