 * \brief DualLin Click example
 * 
 * # Description
 * This example reads and processes data from Dual LIN Clicks.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes driver, and sets bus.
 * 
 * ## Application Task  
 * Reads the received data.
 * 
 * ## Additional Function
 * - duallin_process ( ) - The general process of collecting presponce 
 *                                   that sends a module.
