“ARM体系结构与编程”教学项目的设计与实现

The Design and Implementation of Project-based Teaching about the Course of ARM Architecture and Programming

基于工作过程的项目教学是职业教育提高教学质量的重要方式,如何设计与实现有效的教学项目是教学实施的关键。本课题基于ARM9嵌入式处理器,在无操作系统的条件下,设计并实现三路ADC电位监控仪的教学项目。首先,通过GPIO接口控制LED灯实现监控仪的警示灯;接着,通过ADC接口实现监控仪的数据采集;再次,通过LCD接口实现监控仪的数据显示;最后,通过中断按键实现监控仪数据显示的开启和关闭,并与其他已完成的模块进行整合。经过项目整体测试,结果表明所设计的项目是有效的。

In vocational educationist is important way to improve the quality of teaching with project which is based on the work process.It is the key to the implementation of teaching that how to design and implement well teaching project.This subject is based on ARM9 CPU and without operation system.The teaching and learning project is designed and implemented,which is about three-way voltage monitor.First,warning light is implemented by controlling led light with GPIO interface.Then data collection module is implemented with ADC interface.Then data displaying module is implemented with LCD interface.Finally,the module,which is about turning on or off data displaying,is implemented with extern interrupt button.And then all modules,which are finished,are integrated.The result shows that the teaching and learning project is effective,after the all over project is tested.
