 * \brief DIGIPOT6 Click example
 * 
 * # Description
 * This example showcases how to initialize, configure and use the DIGI POT 6 click module. The
 * click is a digital potentiometer. The potentiometer has a programmable wiper which controls 
 * the resistance between P0W-POA and POW-POB. An external power supply is required for this example.  
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * This function initializes and configures the logger and click modules. This function also sets
 * the click default configuration.
 * 
 * ## Application Task  
 * This function programs the wiper position and shows the current wiper position in the UART
 * console every second.
