Abstract SCM technology today have been vigorously pursued in all fields, and it has gradually entered the lives of ordinary people, many IC manufacturers would have introduced a variety of types of microcontroller s. Among them, superior performance, proven technology and high cost performance and high reliability market firmly occupy the top spot comes as the MCS-51 family of microcontrollers. With the development of technology, it can be used for MCS-51 series microcontroller products developed rapidly increase with, and the corresponding variety of software and development systems are perfected. So we can be very convenient to use existing resources, develop different applications to accomplish different goals or tasks. 源¥自%六:维;论-文'网=www.lwfree.cn
This paper presents a single-chip experimental development board, and a detailed description of the background to the reader development board, describes the functions and principles of each module of this development board and the production process of its PCB board. The development board is designed to help the students learn the basics of the microcontroller, and the system can realize the basic courses, specialized courses of study of knowledge, but also help to complete the completion of the course design and graduation design experiments. The experiment board is described with reference to the microcontroller textbook experiments to design, it can help students to complete a simple test experiments.
