广东东软学院本科毕业设计（论文） 基于 STM32 的指纹识别密码锁的系统设计 The design of fingerprint recognition password lock system based on STM32 single chip microcomputer 摘 要处于现在这个信息发达的时代，指纹识别技术得到了飞速的发展，此得益于其高度的安全性、成本低、还有方便实用。指纹可以说是人们不可能会跟别人存在重复的部分，也就是说可以通过这一个特点，将一个人的指纹预先保存起来，然后与其他的指纹进行比较，可以验证出这个人是否为原本预先保存的那个人。本文是一个基于 STM32 单片机的指纹识别电子密码锁系统设计。控制 AS608 指纹模块以达到实现录取指纹并存储指纹数据的目的，键盘模块选择用矩阵式键盘且通过软件消抖减少其对单片机对应产生的影响，利用 12864 液晶呈现录入和对比的结果，应用直流继电器及发光二极管模拟开锁的操作，继电器及小灯起到提示指令是否完成的作用。广东东软学院本科毕业设计（论文）关键词：STM32 单片机 指纹识别技术 12864 液晶 ANSTRACTIn this information developed era, fingerprint recognition technology has been rapid development, which benefits from its high security, low cost, and convenient and practical.Fingerprint can be said to be the part that people can't repeat with others, that is to say, through this feature, one's fingerprint can be saved in advance, and then compared with other fingerprints, it can be verified whether this person is the person who was saved in advance.This paper is a design of fingerprint recognition electronic password lock system based on STM32.The AS608 fingerprint module is controlled to achieve the purpose of taking fingerprint and storing fingerprint 广东东软学院本科毕业设计（论文）data. Matrix keyboard is selected as the keyboard module and its influence on the corresponding MCU is reduced by software buffeting,The 12864 LCD is used to present the results of input and comparison. The DC relay and LED are used to simulate the operation of unlocking. The relay...
