嵌入式课程递阶教学平台的设计与实现

The Development and Application of Embedded Project Teaching Platform

针对传统嵌入式课程教学平台教学模式单一,辅助实验设置局限性等问题,采用了嵌入式课程递阶教学平台,从嵌入式课程验证性基础实验出发,基于CDIO工程教学模式理念实现理论教学与实践应用一体化,硬件采用核心板和拓展底板分离插拔式设计,底板功能模块化程序可适用于多种微处理器芯片,实现单片机核心板与嵌入式核心板源程序代码共享,满足嵌入式系统分层次递阶教学的要求。重点阐述了多核心板适配同一拓展底板的开放式硬件结构,各个功能模块软件程序模块化过程,以及在CDIO理念下对嵌入式课程教学平台辅助实验进行从验证设计、创新设计及综合设计的递阶式设计思路。实践教学结果表明,嵌入式课程递阶教学平台教学资源丰富,针对性强,教学效果明显,拥有广阔的教学应用前景,可大大提高学生嵌入式系统设计开发能力,激发学生的学习自主性。

With the rapid development of computer technology and wide application, embedded system has been penetrated into in-dustrial control, medical systems, communication and other important areas. Research and study of the embedded system has be-come the focus of college teaching. Embedded development and application teaching platform is based on basic experiments whichcome from the embedded system teaching course. This platform has realized the CDIO engineering implementation principle of realintegration teaching idea. Through different combinations of the core board and expand the bottom plug type structure, along withembedded system development project, makes this platform powerful and capable for various requirement. This paper expounds thedesign blueprint of the platform and its application mode. As an open and comprehensive experiment platform, the project teachingplatform is helpful to enrich students the basic knowledge of embedded system, to improve students' ability in embedded system de-sign and development and to stimulate students' learning autonomy.
