 * \brief Enocean Click example
 * 
 * # Description
 * This example reads and processes data from EnOcean clicks.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes the driver and sets the driver handler.
 * 
 * ## Application Task  
 * Reads the received data and parses it on the USB UART if the response buffer is ready.
 * 
 * ## Additional Function
 * - enocean_process - The general process of collecting data the module sends.
 * - make_response - Driver handler function which stores data in the response buffer.
 * - log_response - Logs the module response on the USB UART.
 * - log_example - Logs button events on the USB UART.
 * - check_response - Checks if the response is ready and logs button events.
