/**
 * @example CompHotspot.ino
 *
 * @par How to Use
 * This example shows that ,when the hot component on the Nextion screen is pressed or released,
 * the debug serial will output the debug information every time. 
 *
 * @author  Wu Pengfei (email:<pengfei.wu@itead.cc>)
 * @date    2015/7/10
 * @updated 2016/12/25 bring HMI up to v0.32 to avoid too old issues
