 * \brief Touchpad Click example
 * 
 * # Description
 * Demo application shows reading of current event:
 *   - touch event (Touch Coordinates)
 *   - Gesture event (gesture type)
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Configuring clicks and log objects.
 * Setting the click in the default configuration.
 * 
 * ## Application Task  
 * Reads every touch and gesture and this data logs to USBUART.
