指纹识别是最常见的生物识别方式,可以用于验证一个人的身份。基于指纹识别的考勤系统已经被广泛应用于各单位。由于指纹识别技术具有巨大的市场应用前景,因此本文重点研究了指纹识别系统的设计,以MSP430F149开发板为平台,利用MSP430F149的串行口外接FM-180指纹识别模块,根据指纹识别模块的指令要求,在IAR设计平台中,采用结构化程序设计方法利用C语言编程实现了基于串行口通信的指纹识别系统。
Fingerprinting is the most common way of biometrics and can be used to verify a person’s identity. Attendance system based on fingerprint identification has been widely used in various units. Because fingerprint identification technology has a huge market application prospect, this paper focuses on the design of fingerprint identification system, MSP430F149 development board as a platform, the use of MSP430F149 serial port external FM-180 fingerprint recognition module, according to the fingerprint recognition module instruction requirements In the IAR design platform, a fingerprint recognition system based on serial port communication is realized by structured programming method and C language programming.
