 * @file main.c
 * @brief USBCSource Click example
 *
 * # Description
 * This is an example that demonstrates the use of the USB-C Source Click board.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initialization driver enables - I2C, set hardware reset and default configuration 
 * and display configuration of the five PDOs, also write log.
 *
 * ## Application Task
 * In this example, we show port status, monitoring, and connections.
 * All data logs write on USB uart changes every 5 sec.
 * 
 * Additional Functions :
 * - void display_port_status ( ) - Display port status info.
 * - void display_monitoring_status ( ) - Display monitoring status info.
 * - void display_connection_status ( ) - Display connection status info.
