摘要
传统教学中,老师教导立体几何结构一直是一大难题。为解决这一问题本文提出研制一种通过μC/OS-Ⅱ嵌入式操作系统控制三维LED发光点阵形式显示立体几何图形的的教学辅助模型,借助操作系统的多任务性与实时性完成功能选择,数据传送和点阵显示等复杂的任务处理。通过配套编写的上位机控制软件将教学内容送至发光点阵模型进行立体化显示。同时在操作系统上嵌入了FAT文件系统,支持数据通过TF卡读取写入。整个系统经验证具有良好的实用性。
In traditional teaching, it’s very hard for the teachers to teach the solid geometry. In order to solve the drawbacks of it, this paper proposes a 3D LED matrix forms model controlled by μC/OS-Ⅱsystems. Using the operating system, the function select,data sending and the picture display will be accomplished. We can send the content to the model by the PC control software which we designed.This system has been proved effective.
