 * \file 
 * \brief Thermostat3 Click example
 * 
 * # Description
 * This application enables usage of the general puprose Thermostat Click to be used with temperature sensors.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initialization driver init
 * 
 * ## Application Task  
 * Waits for valid user input and executes functions based on set of valid commands
 * 
 * *note:* 
 * - Additional Functions :
 *      -void _displayFault( uint8_t f_error )  - Display fault
 *
