平台：小熊派stm32l431开发板
线程信息如下：
main线程
```c
#include <rtthread.h>
#include <rtdevice.h>
#include <board.h>

extern void collect_tast_create(void);
int main(void)
{
  int count = 1;

rt_kprintf("---Welcome use BearPi---\n");

rt_pm_module_release(PM_POWER_ID, PM_SLEEP_MODE_NONE);
  //rt_pm_request(PM_SLEEP_MODE_IDLE);
  rt_pm_module_delay_sleep(PM_POWER_ID, 5000);
  collect_tast_create();

while (1)
  {
      rt_thread_mdelay(10000);
  }

return RT_EOK;
}
```
创建的线程：

#include <rtthread.h>

/* defined the LED pin: PC13 */

void len_init(void)

    rt_pin_mode(LED0_PIN, PIN_MODE_OUTPUT);
}

static void collect_task(void *parameter)
{
    uint32_t i = 0;
    len_init();
    for(;;)
    {

                            10);

rt_thread_startup(&collect_thread);
}
```
组件配置如下：

重写的函数：
```c
rt_tick_t pm_timer_next_timeout_tick(rt_uint8_t mode)
{    switch (mode)
    {
        case PM_SLEEP_MODE_LIGHT:
        case PM_SLEEP_MODE_DEEP:
        case PM_SLEEP_MODE_STANDBY:
        return rt_timer_next_timeout_tick();  /* 从系统软件定时器链表上获取即将超时定时器的timeout tick */
    }
    return RT_TICK_MAX;
}
```
