 * \brief Touchkey2 Click example
 * 
 * # Description
 * This application is touch controller.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initalizes device and makes an initial log.
 * 
 * ## Application Task  
 * Checks if new data byte have received in rx buffer (ready for reading),
   and if ready than reads one byte from rx buffer, that show if and what key is pressed.
