配置

在component library中双击添加rtos模块
再在components中双击这个模块，进入配置界面，完成配置
配置3个led接口为输出
ctrl+s保存，生成代码
添加Task/task_start.c task_start.h task_led.c task_led.h (可在别的地方创建，拖进工程文件夹)

在main.c中添加包含头文件, 时钟, 引脚, rtos初始化

#include "task_start.h"

    CLOCK_SYS_Init(g_clockManConfigsArr,   CLOCK_MANAGER_CONFIG_CNT, g_clockManCallbacksArr, CLOCK_MANAGER_CALLBACK_CNT);
    CLOCK_SYS_UpdateConfiguration(0U, CLOCK_MANAGER_POLICY_AGREEMENT);
    PINS_DRV_Init(NUM_OF_CONFIGURED_PINS, g_pin_mux_InitConfigArr);
    RTOS_Start();
