使用单极霍尔开关US5881和MK64FN1M0VDC12微调性能

/*!
 * \file 
 * \brief UNI HALL Click example
 * 
 * # Description
 * This is a example which demonstrates the use of UNI HALL Click board.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initialization driver enable's - GPIO and start write log.
 * 
 * ## Application Task  
 * Detect the north pole magnetic fields near the UNI HALL Click.
 * Results are being sent to the Usart Terminal where you can track their changes.
 * All data logs on usb uart when magnetic field is detected.
