1. Function description

	/* Briefly describe the project function */
	This routine configures and demonstrates CAN sending and receiving CAN messages in loopback test mode


2. Use environment

	Software development environment:
	IDE tool: KEIL MDK-ARM 5.26
    
	Hardware environment:
	Development Board N32L40XML-STB_V1.0


3. Instructions for use

	/* Describe related module configuration methods; for example: clock, I/O, etc. */
	SystemClock: 64MHz
	USART: TX - PA9, RX - PA10, baud rate 115200
	CAN: RX - PA11, TX - PA12, baud rate 500K, loopback test mode

	/* Describe the test steps and phenomena of the Demo */
	1. After compiling, download the program to reset and run;
	2. Check the serial port printing information, CAN regards the sent message as the received message and saves it, and the program runs normally when the printing information is viewed as received;
