Reading nature's intentions with KP264XTMA1 and STM32F031K6

 * @file main.c
 * @brief Barometer7 Click example
 *
 * # Description
 * This library contains API for Barometer 7 Click driver.
 * The demo application reads and calculate temperature and pressure data.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes SPI driver and log UART.
 * After driver initialization the app set default settings 
 * and display sensor identifier data.
 *
 * ## Application Task
 * This is an example that demonstrates the use of the Barometer 7 Click board™.
 * In this example, display the Pressure ( mBar ) and Temperature ( degree Celsius ) data.
 * Results are being sent to the Usart Terminal where you can track their changes.
 *
 * ## Additional Function
 * - static void display_error ( void )
 *
