Sample Description
|
|
|
================================================================================
|
|
|
功能描述:
|
|
|
此样例演示了采用CANFD协议标准帧轮询方式与PCAN-View的通信功能,MCU首先自动向
|
|
|
PCAN-View发送64byte数据0x0~0x3F,PCAN-View接收到数据后,然后手动通过PCAN-View向
|
|
|
MCU发送ID为0x12F的64byte数据,MCU会自动将接收到数据通过串口打出。
|
|
|
|
|
|
Function descriptions:
|
|
|
This example demonstrates the communication function of using the CANFD protocol
|
|
|
standard frame polling method with PCAN-View. The MCU first automatically sends
|
|
|
64byte data 0x0~0x3F to PCAN-View. After PCAN-View receives the data, it manually
|
|
|
sends 64byte data with ID 0x12F to the MCU through PCAN-View. The MCU will
|
|
|
automatically print the received data through the serial port.

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. 通过USB转CAN模块连接PC、CAN转接板、STK板,连线方式如下;
|
|
|
STK板 CAN转接板
|
|
|
PA11(CAN_RX) --> R21
|
|
|
PA12(CAN_TX) --> R20
|
|
|
GND --> GND
|
|
|
|
|
|
CAN转接板 USB转CAN模块
|
|
|
CAN-H --> CAN-H
|
|
|
CAN-L --> CAN-L
|
|
|
4. 打开PCAN-View,配置PCAN-View连接方式为:CANFD,Clock Frequency:20MHz,
|
|
|
Nominal Bit Rate:500kBit/s,Data Bit Rate:不设置,Standard
|
|
|
5. 复位STK板,观察PCAN-View是否接收到64byte数据0x0~0x3F,PCAN-View接收到表明
|
|
|
STK板发送数据成功,否则表明STK板发送数据失败;
|
|
|
6. PCAN-View接收到数据后,手动通过PCAN-View发送ID为0x12F的64byte数据,观察串口是
|
|
|
否打印PCAN-View发送的数据,如果串口打印,表明STK板接收数据成功,否则STK板接收数
|
|
|
据失败。
|
|
|
|
|
|
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. Connect the PC, CAN adapter board, and STK board through the USB to CAN module,
|
|
|
and the connection method is as follows:
|
|
|
STK board CAN adapter board
|
|
|
PA11(CAN_RX) --> R21
|
|
|
PA12(CAN_TX) --> R20
|
|
|
GND --> GND
|
|
|
|
|
|
CAN adapter board USB to CAN module
|
|
|
CAN-H --> CAN-H
|
|
|
CAN-L --> CAN-L
|
|
|
4. Open PCAN-View and configure the connection method for PCAN-View as CANFD,
|
|
|
Clock Frequency: 20MHz, Nominal Bit Rate: 500kBit/s, Data Bit Rate: not set,
|
|
|
Standard
|
|
|
5. Reset the STK board and observe if PCAN View has received 64byte data from 0x0
|
|
|
to 0x3F. PCAN View's reception indicates that the STK board has successfully
|
|
|
sent data, otherwise it indicates that the STK board has failed to send data;
|
|
|
6. After receiving the data, PCAN-View manually sends 64byte data with ID 0x12F
|
|
|
through PCAN-View. Observe whether the serial port prints the data sent by
|
|
|
PCAN-View. If the serial port prints, it indicates that the STK board has
|
|
|
successfully received the data, otherwise the STK board has failed to receive
|
|
|
the data.
