1 引 言

《单片原理及应用》是一门技术性、应用性很强的学科，实践教学是它的一个极为重要的环节。不论是硬件扩展、接口应用还是编程方法、程序调试，都离不开实验教学。如果不在切实认真地抓好学生的实践技能的锻炼上下功夫，单凭课堂理论课学习，势必出现理论与实践脱节的局面。任随书本上把单片机技术介绍得多么重要、多么实用多么好用，同学们仍然会感到那只是空中楼阁，离自己十分遥远，或者会感到对它失去兴趣，或者会感到它高深莫测无从下手，这些情况都会令课堂教学的效果大打折扣。

-1 Introduction

"Principle and Application of monolithic" is a technical, applied a strong discipline, practice teaching is one of its most important aspects. Expansion of both the hardware and interface application or programming, program debugging, are inseparable from experimental teaching. If you do not truly grasp serious practical skills training of students work hard, study alone classroom theory course, theory and practice will inevitably arise out of line situation. With the books of any descr iption to just how important SCM technology, how much useful practical, the students still feel that this moment, very far away from their own, or feel lost interest in it, or will find it unfathomable no start, These conditions will result in greatly reduced the effect of classroom teaching.
