摘要
采用USB控制芯片PDIUSBD12和微控制器AT89S52构成的硬件平台,简化了RFID阅读器与PC之间的数据传输。基于HID1.1协议的程序设计将RFID阅读器枚举为PC的一个外接HID键盘,省去驱动程序的安装。只要打开记事本就能记录电子标签的EPC、TID等特征信息,可满足快速发展的RFID产业对RFID阅读器多样性的需求。
USB control chip PDIUSBD12 and microcontroller AT89S52 are used to construct a hardware platform, and data transmission between RFID reader and PC is simplified. The program design based on HID 1.1 protocol treats RFID reader as an external HID keyboard of PC, and avoids the installation of driver. EPC, TID and other features of the electronic tag are recorded as long as you open the wotebook software. The design can meet the needs of RFID industry for the diversity of RFID Reader.
