uCOS-II任务建立示例

本文主要是介绍uCOS-II任务建立示例，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

#include "config.h"
#include "stdlib.h"

#define          LED1        (1<<18)                    // P1.18控制LED1

#define TaskStkLengh 64    // 定义用户任务的堆栈长度

OS_STK TaskLED1Stk[TaskStkLengh];
OS_STK TaskLED2Stk[TaskStkLengh];

void TaskStart(void *pdata);    //Task0 任务0

void TaskLED2(void *pdata);
