我正在尝试用esp8266和ws2812b发光二极管做一个闹钟。在闹钟时间它必须调用日出（）函数。当我直接把它放在循环函数中时，日出（）函数工作正常。但它在闹钟触发器中不工作。

if (AlarmData.AlarmOn[Current.Day])
  {
    if (!AlarmActive)//do not enter this routine if alarm already active
    {
      if (Current.Hour == AlarmData.Hour[Current.Day])
      {
        if (Current.Minute == AlarmData.Minute[Current.Day])
        {
          if (Current.Second > 0 && Current.Second < 3)
          {
            AlarmActive = true;
            sunrise();
            alarmTriggerTime = micros();
            Serial.println("Its time for your alarm!");

          }
        }
      }
    }
  }

我的代码如下.提前感谢您的帮助
