根据系统设计对芯片的性能、功耗、信息安全和传输速率的要求,选用STM32F103RBT6为阅读器的微控制器。,经实验测试,该阅读器可触摸操控,能读写$50和$70卡,具有数据存储功能;采用锂电池供电,充电时电源自动切换,具有待机时间长等功能。
The system was designed from some aspects, which were chip selections, power consumption, information security, transtoission rate, etc. The STM32FI03RBT6 was the reader micro-controller. This reader, which hads been tested, could louch control, read and write $50 and $70 card, and has data store function. It could use lithium battery, to supply power, and the pow er could automatically switch when the lithium battery charged, the reader had a long standby time.
