摘要
阐述一款基于DSP(Digital Signal Processor)的嵌入式指纹识别系统,对其硬件设计电路和软件设计进行了详细的论述。设计了双电源切换系统,通过SPI协议与指纹采集头FPC1011C和液晶屏进行通信,能够方便地进行指纹采集、注册、匹配,可实时显示处理结果,并把数据及结果通过RS232传送到电脑终端。另外,系统既可以脱机使用,也可与PC联机使用。
The paper presents a fingerprint identification system,and describes the hardware circuit and the software design.System duplex-power exchange system is designed and communication with FPC1011C and LCD is achieved through SPI protocol.The system realizes fingerprint capture,register and match,and displays the identification result in real-time.It sends data to the computer terminal with RS232.This system can be used both off-PC and on-PC.
