 * 
 * # Description
 * Demo application shows is reading current data in mA using Hall current 4 Click.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Configuring Clicks and log objects.
 * 
 * ## Application Task  
 * Reads Current value in mA and logs this data to USBUART every 1 sec.
