基于STM32的指纹识别密码锁的系统设计

广东东软学院本科毕业设计〔论文)ANSTRACTIn this information developed era,fingerprint recognition technologyhas been rapid development,which benefits from its high security,low cost,and convenient and practical.Fingerprint can be said to be the part thatpeople can't repeat with others,that is to say,through this feature,one'sfingerprint can be saved in advance,and then compared with otherfingerprints,it can be verified whether this person is the person who wassaved in advance.This paper is a design of fingerprint recognition electronicpassword lock system based on STM32.The AS608 fingerprint module iscontrolled to achieve the purpose of taking fingerprint and storing fingerprintdata.Matrix keyboard is selected as the keyboard module and its influenceon the corresponding MCU is reduced by software buffeting,The 12864 LCDis used to present the results of input and comparison.The DC relay andLED are used to simulate the operation of unlocking.The relay and smalllamp play the role of prompting whether the instruction is completed.Keywords:STM32 single chip fingerprint recognition technology 12864liquid crystal
