 * \brief MagneticRotary Click example
 * 
 * # Description
 * On every 500 miliseconds reads a magnetic field angle calculated to degrees for channel A
 * in Single-Ended Mode and logs results on uart terminal. 
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes peripherals, pins, SPI interface for communication with the device.
 * 
 * ## Application Task  
 * Reads a magnetic field angle calculated to degrees for channel A
 * in Single-Ended Mode and logs results on uart terminal.
 * Repeats operation every 500 milliseconds.
 * Note : The angle can be measured in the range from -90 to 90 degrees.
