基于S6700芯片和Tag-it协议标准的读写器

The HF reader based on S6700 chip and Tag-it protocol

本文采用TI公司的多协议收发器芯片S6700,结合At鄄mel89C52MCU,设计了基于Tagit协议的读写器。提出的PALM设备和读写器整合的方案。此方案将大大降低了开发的成本,提高读写器的使用灵活性。硬件上通过PALM的串口结合PALM设备和读写器。软件上采用J2ME进行开发。本文将着重介绍S6700通信协议和Tagit协议标准。

In this paper, a HF reader is designed by combining a PALM. The MCU is used to control the S6700 chip to complete the basic request/response commands. Firstly, the TI S6700 chip was introduced and the design is presented on hardware. Secondly, the paper particularly explains the communication protocol of S6700 chip and Tag-it protocol. Finally, It is explained what we could benefit from the new design and how the HF reader combines with the PALM device.
