 * \brief Rtd 2 Click example
 * 
 * # Description
 * RTD 2 Click board is commonly used for measuring ambient temperature
 * from the PT100 3-wire temperature probe.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes the driver, performs a hardware reset, and sets the Click 
 * default configuration.
 * 
 * ## Application Task  
 * Reads an ambient temperature measured by the PT100 3-wire temperature probe
 * connected to the RTD 2 Click board, and logs the results on the USB UART each second.
