 * \brief MBusSlave Click example
 * 
 * # Description
 * This example reads and processes data from M-Bus Slave clicks.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes the driver.
 * 
 * ## Application Task  
 * Depending on the selected mode, it reads all the received data or sends the desired message
 * every 2 seconds.
 * 
 * ## Additional Function
 * - mbusslave_process ( ) - The general process of collecting the received data.
