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。
基于工作過程的項目教學是職業教育提高教學質量的重要方式,如何設計與實現有效的教學項目是教學實施的關鍵。本課題基于ARM9嵌入式處理器,在無操作繫統的條件下,設計併實現三路ADC電位鑑控儀的教學項目。首先,通過GPIO接口控製LED燈實現鑑控儀的警示燈;接著,通過ADC接口實現鑑控儀的數據採集;再次,通過LCD接口實現鑑控儀的數據顯示;最後,通過中斷按鍵實現鑑控儀數據顯示的開啟和關閉,併與其他已完成的模塊進行整閤。經過項目整體測試,結果錶明所設計的項目是有效的。

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.
