The hardware of fingerprint access control system is mainly composed of
microprocessor, fingerprint identification module, LCD module, keyboard,
real-time clock / calendar chip, electronic lock and power supply. As
the upper computer of the system, the microprocessor controls the whole
system. Fingerprint identification module mainly completes the
collection, comparison, storage, deletion and other functions of
fingerprint features. The LCD module is used to display the information
of door opening record, real-time clock and operation prompt, and forms
the human-machine interface with the keyboard.

According to the system function, the software is mainly composed of
fingerprint processing module, LCD module, real-time clock module and
keyboard scanning module. The fingerprint processing module is mainly
responsible for the information processing of commands and return codes
between the microprocessor and fingerprint identification module; the
LCD module compiles the driver program according to the timing of the
LCD module to realize the purpose of displaying Chinese characters and
characters; the real-time clock module compiles the communication
program according to the timing of the clock chip to realize the reading
and writing operation of the clock chip; the keyboard scanning module
Block is to write a keyboard program according to the design principle
of the keyboard to identify whether there is a key action and press the
key numbe
