摘要
为了满足超市射频识别读写器系统应用的需求,设计了基于嵌入式实时操作系统FreeRTOS与ISO/IEC14443A标准的非接触式CPU电子纸可视卡读写器系统。采用STM32F107VCT6微控制器和MFRC522射频芯片等进行相关的硬件电路设计,通过移植FreeRTOS内核实现硬件资源管理和任务调度;在此基础上,给出了非接触式CPU电子纸可视卡电子纸显示模块中片内操作系统的设计原理;实现了一个可视电子钱包的应用。实验结果表明,该读写器系统具有读写速度快、准确率高、可靠性强的优势,使用方便快捷。
To meet the demands for the application of radio frequency identification reader system in supermarkets, a reader sys- tem for a non-contract visual CPU card with an electronic paper （E-paper） is designed based on ISO/IEC 14443A and embedded open source operating system FreeRTOS. Firstly, the chips STM32F107VCT6 and MFRC522 are used in the hardware desig ning. The resource management and task scheduling are implemented by transplanting a FreeRTOS kernel. Then the design principle of the non-contact visual CPU card with the E-paper in COS （chip operating system） is presented. Finally a visual elec- tronic wallet is completed as an experiment. Experimental results show that the reader system is convenient with high speed and accuracy, which is reliable.
