 * @file main.c
 * @brief Joystick 3 Click example
 *
 * # Description
 * This example demonstrates the use of the joystick 3 Click board by reading
 * and displaying the raw ADC for X and Y axis, as well as the joystick angle and position
 * calculated from those ADC readings.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and logger.
 *
 * ## Application Task
 * Reads the raw ADC measurements for X and Y axis, and calculates the joystick angle and position
 * from those readings. The results will be displayed on the USB UART approximately every 100ms.
