 * 
 * # Description
 * Demo application shows basic temperature reading using Thermo K Click.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Configuring Clicks and log objects.
 * Reads the device ID and also checks the Click and MCU communication.
 * 
 * ## Application Task  
 * Reads Temperature data(Type K probe) and this data logs to USBUART every 500ms.
