 * \brief CapTouch5 Click example
 * 
 * # Description
 * This demo app demonstrates basic functionality of CapTouch 5 Click
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes I2C module and driver, tests communication and configures device
 * 
 * ## Application Task  
 * Waiting for touch sensor to detect something and then logs what is touched
 * 
 * *note:* 
 * Click will go to sleep if doesn't get any command in 340ms
 * When you start device try restarting your board few times to start device
