Unlock the potential of ISO 9141 with L9637 and ATmega328P

 * # Description
 * This example demonstrates the use of an ISO 9141 click board by showing
 * the communication between the two click boards.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initalizes device and makes an initial log.
 * 
 * ## Application Task
 * Depending on the selected application mode, it reads all the received data or 
 * sends the desired text message once per second.
