| In recent years,there is a growing demand for embedded products,which greatly promoted the development of embedded technology,embedded technology to all areas,so it is of great significance for the research and construction of the embedded system based on embedded operating system.A sound management system of enterprises directly reflects the company’s good or bad aspect,and the important part of the enterprise management system is the personnel system,it is directly related to the company’s benefits and the enthusiasm of the staff work,so the company staff attendance management is an important issue which every company will face.The S3C2440 embedded microprocessor based on ARM9 kernel is used in the embedded fingerprint identification system in this paper,and embedded source open Linux operating system,to achieve the staff attendance record and employee information management and storage.This paper mainly describes the construction of the embedded system based on Linux operating system,including the establishment of cross compiler environment,the boot process of Bootloader,the U-Boot,the Linux kernel,the YAFFS and the driver.Finally,the application of the embedded fingerprint attendance machine with touch technology is realized by Qt-Embedded.This paper focuses on the development of embedded system,the difficulty is the construction of the embedded system platform of software and hardware,and the realization of the graphical user interface.The innovation points are the system embedded database,to achieve the offline management and attendance machine touch operation.In addition,the system is embedded by the Web server,to meet the rapid development of the network era. |
