使用LM2903和MK64FN1M0VDC12获得前所未有的电压洞察

 * \brief Comparator Click example
 * 
 * # Description
 * Comparator Click represents board equipped with two 
 * independent precise voltage comparators.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Application Init performs Logger and Click initialization.
 * 
 * ## Application Task  
 * Comparator Click checks state of the O1 and O2 pins. 
 * Results are being sent to the UART Terminal 
 * where you can track their changes. 
 * All data logs write on USB UART and changes for every 1 sec.
