 * \brief Joystick2 Click example
 * 
 * # Description
 * The demo application shows reading the joistick position ..
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Configuring clicks and log objects.
 * Reset device and settings the click in the default configuration.
 * 
 * ## Application Task  
 * It reads the position of the joystick,
 * if it detects that the joystick has moved from the zero position,
 * it prints a message about the current position.
 *
 * @note: The I2C peripheral lines external pull up can be required.
