驱动程序为4个步进驱动器

应用背景一个生物度量为基础的电子考勤记录是一个独立的设备，人们记录考勤。它有一个存储他们的名字，人们数据库部门，以及每个人的号码。登记考勤，一个人可以使用代码附加到他/她的名字从数据库和网页拉记录会出现提示这样的人，已经把在一个正确的代码将他/她的手指在指纹扫描仪的拇指。指纹扫描仪来扫描指纹与数据库中存储的比较。如果找到匹配，人将登记参加的那一天。管理员密码可以用来拉，参加了一天的人的名字。 ；关键技术在本项目设计的主要技术是生物度量。确保电子考勤的真实性为目标，在项目的追求。 ；AT89C51  ；微控制器技术这项技术特色的设计。 ；利用程序的AT89C51，启动指纹扫描仪来扫描指纹，并将其存储在数据库；

The widespread use of embedded systems mandates the development of industrial software design methods, i.e. computer-aided design and engineering of embedded applications using formal models (frameworks) and standardized prefabricated components, much in the same way as in other mature areas of engineering such as mechanical engineering and electronics. These guidelines have been used to develop Component-based Design of Software for Embedded Systems (COMDES). The paper gives an overview of the COMDES framework, followed by a presentation of a generic component types, such as function blocks, activities and function units. The execution of function units is discussed in the context of a newly developed execution model, i.e. timed-multitasking, which has been extended to distributed embedded systems.
