SAKSHAT提供的蜂鸣器使用方法

当前SAKSHAT为我们提供的方法参考：http://wiki.nxez.com/saks:sdk:libraries:buzzer

Buzzer
有源蜂鸣器类，控制蜂鸣器对象发出声音。 方法

初始化对象，设置蜂鸣器引脚和触发电平（高电平或低电平触发）。

返回当前蜂鸣器工作状态。

设置蜂鸣器开始工作。

设置蜂鸣器停止工作。

设置蜂鸣器鸣叫 seconds 的时间。seconds 为毫秒时间。
beepAction(self, secs, sleepsecs, times)[/python]

设置蜂鸣器鸣叫 seconds 的时间，并间隔 sleepsecs 的时间再次鸣叫，如此周而复始 times 次。seconds 为毫秒时间。sleepsecs 为毫秒时间。times 为次数。
