摘要
当前单片机实验教学设备存在实验内容简单、程序固定的弊端,学生自主操作的空间很小,与工程实际相差甚远。针对这一问题提出改进设计方案,从工程开发的角度设计各功能模块,基于开放式设计理念,各功能模块与母板采用可拆卸式的连接,方便组成不同实验的硬件电路,具有很强的可扩展性。既可以完成基本的实验教学需要,又增加了灵活操作的空间,学生可以自主进行系统硬件和软件的设计,切实锻炼了学生的实践技能,培养了学生的工程意识。目前,该实验箱已经在两所院校推广应用。
Currently MCU experimental teaching equipments have the shortcomings of simplification and immobilization of the experiment content.There is little room for students to autonomous operation. It is far from engineering. To solve this problem, an improved design is proposed. From the engineering point of view, the function modules are designed. Based on the open design concept, By removable connection between the functional modules and the motherboard, it is easy to experiment with different hardware components. It is scalable highly. It not only can complete the basic experimental teaching needs, but also increase flexibility in operating room. Students can design the hardware and software by themselves. The students practice skill is exercised effectively, and the engineering sense is improved. Currently, the experimental box has been popularized and applied in two universities.
