 * \brief Ldc1101 Click example
 * 
 * # Description
 * Example demonstrates measurement of inductance change depending on the linear motion of the metal object.
 * Induction of the linear metal position depends on the type of metal and the configuration.
 * 
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes I2C module and sets CS pin as OUTPUT and PWM and INT pin sa INPUT.
 * Driver intialization, standard configurations and start measurement.
 * 
 * ## Application Task  
 * Reads RP data and logs data to USBUART every 1 sec.
