 * \brief Boost4 Click example
 * 
 * # Description
 * This example demonstrates the use of Boost 4 Click board.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes the driver and logger, and enables the Click board.
 * 
 * ## Application Task  
 * Set the desired output voltage by cycling through a couple of predefined voltage values.
 * All data are being logged on USB UART every 3 seconds.
 * 
 * @note
 * Vout cannot be set to voltage below Vin. So in order to get all values at Vout exactly 
 * as it is set in this example, please provide 2.5V to Vin.
