摘要
以集成以太网控制器和CAN总线控制器的ARM7处理器LPC2368为核心,MBF200芯片为指纹传感器模块,PCA82C250为CAN总线收发器芯片,重点阐述了系统接口部分硬件电路图设计和系统软件构建。实现了低成本,高可靠性多节点指纹识别系统的设计。
This paper introduces the method of design of a embedded fingerprint identification system in detail taking microprocessor LPC2368 as the core PCA82C250 as the CAN-BUS receive and transmit controller chip and MBF200 as finger sensor. Firstly, it briefly introduces the hardware design of interfaces and system software design, Secondly, it briefly states the fingerprint identification system design is cheap and available in practical.
