 * \brief Pressure8 Click example
 * 
 * # Description
 * This application reads pressure data.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initialization device and logger module, reset device and set PSI range.
 * 
 * ## Application Task  
 * Reads pressure data in mBar and logs it on the USB UART once per second.
