================================================================================
|
|
|
功能描述：
|
|
|
此样例演示了采用CANFD协议、扩展帧、内部回环的轮询方式与PCAN-View的通信功能，MCU
|
|
|
首先自动向发送64byte数据0x0~0x3f，MCU接收到数据后，自动将接收到数据通过串口打出。
|

Function descriptions:
|
|
|
This example demonstrates the communication function with PCAN-View using the
|
|
|
CANFD protocol, extended frames, and internal loopback polling method. The MCU
|
|
|
first automatically sends 64byte data 0x0~0x3f to the. After receiving the data,
|
|
|
the MCU automatically prints the received data through the serial port.

测试环境：
|
|
|
测试用板：PY32F403_STK
|
|
|
MDK版本： 5.28
|
|
|
IAR版本： 9.20
|
|
|
GCC版本：GNU Arm Embedded Toolchain 10.3-2021.10
|
|
|
|
|
|
Test environment:
|
|
|
Test board: PY32F403_STK
|
|
|
MDK Version: 5.28
|
|
|
IAR Version: 9.20
|

使用步骤：
|
|
|
1. 编译并下载程序；
|
|
|
2. 通过USB转TTL模块连接PC与STK板,STK板与USB转TTL模块的连线方式如下；
|
|
|
STK板 USB转TTL模块
|
|
|
PA02(TX) --> RX
|
|
|
PA03(RX) --> TX
|
|
|
GND --> GND
|
|
|
3. 复位STK板，观察串口是否打印64byte数据0x0~0x3f，如果串口打印，表明内部回环模式
|
|
|
测试成功。
|
|
|
|
|
|
Example execution steps:
|
|
|
1. Compile and download the program.
|
|
|
2. Connect the PC and STK board with a USB-to-TTL module. The connections
|
|
|
between the STK board and the USB-to-TTL module are as follows:
|
|
|
STK board USB-to-TTL module
|
|
|
PA02(TX) --> RX
|
|
|
PA03(RX) --> TX
|
|
|
GND --> GND
|
|
|
3. Reset the STK board and observe whether the serial port prints 64byte data
|
|
|
0x0~0x3f. If the serial port prints, it indicates that the internal loop back
|
|
|
mode test has been successful.
