 * \brief QiReceiver Click example
 * 
 * # Description
 * This application reads voltage, current and frequency.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 *  Initalizes I2C driver, enables the device and makes an initial log.
 * 
 * ## Application Task  
 * This is an example that shows the most important
 * functions that Qi Receiver click has, it mesures current voltage, amperage and frequency.
 * 
 * ## Note
 * Click board needs to have external power ( Qi transmitter ) in order to work, otherwise I2C communication won't work.
 * If Qi Transmitter is removed from click board it will stop working, if you return it you should restart your application.
 * You will now when Click board has power and is ready to start application when red STAT led is on, when it's off I2C communication won't work.
