Design a more compact and cost-effective CAN solution with NCV7356 and TM4C123GH6PZ

 * \brief SingleWireCan Click example
 * 
 * # Description
 * This example demonstrate the use of Single Wire CAN click board.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes the driver and configures the click for the normal operation mode.
 * 
 * ## Application Task  
 * Depending on the selected mode, it reads all the received data or sends the desired message
 * every 2 seconds.
 * 
 * ## Additional Function
 * - singlewirecan_process ( ) - The general process of collecting the received data.
