1、功能说明

/* 简单描述工程功能 */
    这个例程配置并演示CAN在环回测试模式下收发CAN报文情况

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

/* 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，环回测试模式

/* 描述Demo的测试步骤和现象 */
    1.编译后下载程序复位运行；
    2.CAN发送一帧消息，然后在验证通过后再发送另一帧消息。通过CAN设备，可以看到消息是在循环发送。

4、注意事项

1. Function description

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

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

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

   /* Describe the test steps and phenomena of Demo */

   1. After compiling, download the program to reset and run;
   2. CAN sends a frame of message, and then sends another frame of message after the verification is passed. Through the CAN device, you can see that the message is sent in a loop.
