摘要
对于抽象概念的教学,辅助教学工具是必要的手段之一,教具在教学中有着不可替代的作用。传统的教具制作多是利用简易材料来描述比较直观的物理现象。本文提出了教具制作的一种新的思路:用FPGA为控制器,来设计一种电子化的教具。本文以设计LC充放电演示教具为例,用FPGA控制LED的闪烁来演示电荷的移动。本文详细描述了设计的需求分析,及用VHDL实现的算法,最后给出了仿真结果。
The auxiliary tools are necessary in teaching abstract conceptions. Demonstrations can not be replaced. The traditional demonstrations usually utilize simple materials to describe the intuitional physics phenomena. A new idea, electronic demonstrations controlled by FPGA, is proposed in this paper. The design of LC charge and discharge demonstration is used as an example： the shift of electric charge is demonstrated by glitter of LEDs, which are controlled by FPGA. Meanwhile, requirement analysis and algorithm with VHDL, as well as simulation result of the design, are illustrated in details.
