雷达电子干扰模拟器嵌入式串口控制设备软件开发

摘要

介绍一种应用于雷达电子干扰模拟器的基于实时操作系统μC/OS-Ⅱ的串口控制设备的软件开发方法。以ARM7微处理器LPC2138、矩阵键盘和液晶显示屏组成的硬件平台为例，介绍了用户任务设计和人机界面开发的软件设计思想，确定了系统任务划分及优先级设定，给出了软件启动流程和相应的编程代码，说明了人机界面的制作步骤。所研制的雷达电子干扰模拟器具有良好的人机界面且操作方便。%This paper introduces a method of software developing of embedded serial port control device based onμC/OS-II embedded operating system,which is applied to the radar electronic jamming simulator. Its software design idea was presented by taking ARM7 microprocessor LPC2138,matrix keyboard and LCD as an example of hardware platform example. The division of task and assignment of software priority is determined. The working flow of its programming and detail code is provided.The production steps of human-machine interface is described. This simulator not only has good interface but also can be operated easily.
