 * @file main.c
 * @brief Altitude6 Click example
 *
 * # Description
 * This library contains API for Altitude 6 Click driver.
 * The demo application reads and calculate 
 * temperature, pressure and altitude data.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes I2C or SPI driver and log UART.
 * After driver initialization the app set 
 * driver interface setup and  default settings.
 *
 * ## Application Task
 * This is an example that demonstrates the use of the Altitude 6 Click board™.
 * In this example, display the Altitude ( m ), 
 * Pressure ( mBar ) and Temperature ( degree Celsius ) data.
 * Results are being sent to the Usart Terminal where you can track their changes.
