 * @file main.c
 * @brief Barometer6 Click example
 *
 * # Description
 * This is an example that demonstrates the use of the Barometer 6 Click board.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initalizes SPI or I2C driver, applies default settings and reads Chip ID.
 *
 * ## Application Task
 * Demonstrates use of Barometer 6 click board by reading pressure and temperature data seconds 
 * and logging it on the UART terminal.
