基于uCOS-II的时钟设计实验报告

1、嵌入式系统综合实验报告实验内容基于uC/OS-II的时钟设计系自动控制专 业自动化班 级学 号学生姓名指导教师2011年05月25日基于uC/OS-II的时钟设计一 实验要求1. 按正常逻辑显示“年-月-日”，“时：分：秒”，其中分与秒间“：”每0.5秒闪烁1次。2. 可利用键盘的上，下，左，右键进行日期，时间设置；按“ESC”退出程序；3. 可利用键盘的上，下键进行走时快慢调整，以便检验走时逻辑可选功能；4. 功能的实现过程中，必须体现所学的uC/OS-II相关知识，信号量、互斥量、消息邮箱、消息队列必须用到；5. 独立完成，正常演示结果，且正确回答老师抽查问题。二 实验设计思想1、划分了6

2、个任务，分别为year、month、day、hour、min、sec，建立了2个信号量semsec、semhalfsec。2、dis1Num(char x, char y, char num)表示在界面（x，y）坐标上显示一位数，dis2Num(char x, char y, char num)表示两位数组成一个时间块。3、用方向键定义了4个key，left、right可以进行年月日时分秒的切换，up、down可以对每一项的数值的加减。4、每过一个信号量semsec，时间加1秒，OSSemPend(semHalfSec, 0, &err)调用semhalfsec实现两个点亮半秒、暗半秒的闪烁功

3、能。OSMboxPost(mboxPosNumMode, &dateTime)调用semhalfsec实现被选中的任务时间块的闪烁。5、通过key实现任务之间的调度，left和right方向键对时间块的选择用到了互斥量。6、OSMboxPost(mboxPosNumMode, &dateTime)把dateTime的地址发送给mboxPosNumMode。7、。“消息队列”是在消息的传输过程中保存消息的容器。三 具体程序实现实验结果代码/* uC/OS-II* The Real-Time Kernel* description:移植uC/OS-II(2.51 Kernal)在Visual C+
