Fingerprint identification system based on ARM
Abstract: With the rapid development of information technology, the security of their information is required to gradually increase, which has a high security fingerprint recognition technology in the rapid development of people's attention. Most of the current fingerprint identification systems are based on PC, which are a lot of problems in mobile and portability. The current status of fingerprint identification is analyzed briefly and a fingerprint identification system based on STM32 is designed with research on embedded system and fingerprint identification in this paper. The fingerprint acquisition module FPM10A is used in this system. The communication between the fingerprint acquisition module and the single chip microcomputer is completed and the functions such as fingerprint input, fingerprint identification and fingerprint clearing are realized by studying the communication protocol. The fingerprint acquisition and processing algorithms are also studied in this paper. The fingerprint recognition system designed in this paper has the characteristics of small size, high mobility, and practical value.
Keywords: STM32; fingerprint identification processing; FPM10A; communication protocol
