使用MCP2542和STM32G431RB革新汽车和工业通信

/*!
 * \file 
 * \brief Mcp2542 Click example
 * 
 * # Description
 * This application use for comunication.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Driver intialization.
 * 
 * ## Application Task  
 * Checks if new data byte have received in rx buffer (ready for reading),
 * and if ready than reads one byte from rx buffer. In second case aplication task writes
 * message data via UART.
