使用ATA663211和STM32L496AG在汽车和工业环境中实现实时监控和控制

 * \brief Ata663211 Click example
 * 
 * # Description
 * This example demonstrates the use of an ATA663211 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 with the message counter once per second.
