使用MLX90333和ATmega328P精确检测所有三维方向的磁场强度

/*!
 * \file 
 * \brief c3DHall Click example
 * 
 * # Description
 * This application use to determine angle position.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initialization driver enable's - SPI and start write log.
 * 
 * ## Application Task  
 * This is a example which demonstrates the use of 3D Hall Click board.
 * 3D Hall Click communicates with register via SPI by read data from register
 * and calculate Alpha and Beta angle position.
 * Results are being sent to the Usart Terminal where you can track their changes.
 * All data logs on usb uart.
 * 
 * ## NOTE
 * The maximal SPI Clock frequency for MLX90333 sensor is about 430 Khz. 
 * If you are expiriencing issues, please try to lower MCU's main clock frequency.
