摘要：《单片机原理与应用》课程对于许多专业来说是一门重要的专业基础课。目前，国内学校大多是以MCS-51单片机(简称51系列)为主要内容进行教学。近年来，随着半导体技术的飞速发展，大量高性能、采用新技术的嵌入式微处理器的面世，给传统的单片机教学带来了冲击，对单片机课程教学方法与教学设备的改进提出了新的课题。本设计采用Atmega16单片机作为实验平台的主芯片，通过对单片机学习过程中常用实验模块的分析，设计出实验平台的外围电路，并在实验平台的基础上编写出实验指导书。在实验平台上可以进行LED数码管显示、键盘扫描、电子音乐、串口通信等基本实验。通过这些实验，使学生更加深入的了解单片机，培养学习兴趣，提高实际操作能力。

The design of Embedded Platform based on AVR MCU
Abstract：The principle and the application of MCU is an important course for many majors. Currently, MCS-51 series MCU is adopted by most schools in China as their teaching content. However, with the development of semi-conductor technology and the appearance of high capability and Embedded Microprocessor Unit, which brings an impact on the traditional way of MCU teaching and a new task for the improvement of teaching method and facilities of MCU course. Adopting the Atmega16 MCU as the main chip of the experiment platform, we design out the peripheral circuit of the experiment platform by analyzing the experiment modes commonly used in the study of MCU. And an experiment guidebook based on its platform is also compiled. On this platform, we can carry out basic experiments like LED digital pipe display, keyboard scanning, electric music, Serial Communication, etc. Through these experiments, students will get more familiar with MCU and be more interested in it through these experiments, and it is easy to improve their ability of practical operation.
