+/**
+ * @example CompTimer.ino
+ * 
+ * @par How to Use
+ * This example shows that ,when the OFF button component on the Nextion screen is released,
+ * the timer will opened,the text will show number changed and push the ADDTIME button timer 
+ * cycle value will increase,when push the DECTIME button timer cycle  value will reduce.
+ *
+ * @author huang xianming (email:<xianming.huang@itead.cc>)
+ * @date    2015/8/25
+ * @updated 2016/12/25 bring HMI up to v0.32 to avoid too old issues
+ * @convert by Patrick Martin, no other changes made
