1、功能说明
    1、CAN发送接收例程


2、使用环境

    软件开发环境：KEIL MDK-ARM V5.34.0.0
                  IAR EWARM 8.50.1

    硬件环境：基于评估板N32G430C8L7-STB V1.0开发


3、使用说明
    
    系统配置；
    /* 描述相关模块配置方法；例如:时钟，I/O等 */
        SystemClock：128MHz
        CAN： RX - PB8，TX - PB9，波特率500K，正常模式

    /* 描述Demo的测试步骤和现象 */
        1.编译后下载程序复位运行；
        2.当CAN收到一帧报文，就发送一帧报文
                     
                 
4、注意事项


1. Function description
    1. The reference program for CAN sending and receiving.


2. Use environment

    Software development environment: KEIL MDK-ARM V5.34.0.0
    Hardware environment: Developed based on the evaluation board N32G430C8L7-STB V1.0


3. Instructions for use
    
    System Configuration;
    /* Describe the configuration method of related modules; for example: clock, I/O, etc. */
    SystemClock: 128MHz
    CAN: RX-PB8, TX-PB9, baud rate 500K, normal mode

    /* Describe the test steps and phenomena of Demo */
    1. After compiling, download the program to reset and run;
    2. When CAN receives a frame of message, send it to a frame of message
                     
                 
4. Matters needing attention
     without
