带系统的ucos2控制LED灯课程设计4页

1、操作说明：程序共有两个任务，任务一：前三个灯从上往下依次灭一个。任务二：后三个灯从上往下依次灭一个。按下第一个键六个灯全亮，按下第二个键上面下面三个灯全亮，上面三个正常循环。源程序：#include "config.h"#defineTask_Stk_Size64/Define the Task1 stack length 定义用户任务0的堆栈长度OS_STKTaskStartStk1Task_Stk_Size;/Define the Task1 stack 定义用户任务0的堆栈void TaskStart1(void *data);/Task0 任务1OS_STKTask
