在UCOSII里面创建3个任务：开始任务、LED0任务和LED1任务，开始任务用于创建其他（LED0和LED1）任务，之后挂起；LED0任务用于控制DS0的亮灭，DS0每秒钟亮80ms；LED1任务用于控制DS1的亮灭，DS1亮300ms，灭300ms，依次循环。(Create three tasks in UCOSII: start task, LED 0 task and LED 1 task, start task to create other tasks (LED 0 and LED 1), then hang up; LED 0 task to control the brightness of DS0, DS0 80 ms per second; LED 1 task to control the brightness of DS1, DS1 300 ms, 300 ms, in turn, cycle.)

以实例为背景学习基于MFC的WINDOWS应用程序设计，编写一个模拟时钟程序，此程序在屏幕左边有一个指针式钟面，右方有两个矩形框，上面以数字方式显示日期和时间，该时间应与指针显示的时间一致，下方的矩形框作为秒表。用菜单选项或按钮设置时间和秒表。时间不必与机器系统时间相同，可任意设置。(Background-instance learning WINDOWS MFC-based application design, the preparation of an analog clock program, this program has a pointer on the screen on the left clock face, on the right there are two rectangular box, above digitally display the date and time, which should be consistent with the pointer display time, and the lower rectangular box as a stopwatch. With a menu option or button to set the time and stopwatch. Time Machine does not have the same system time can be set arbitrarily.)
