例子 / Examples

这个例子用linux socketcan. Windows用户可以用个linux虚拟机。WSL应该也可以。

This example uses linux socketcan. Windows users can run it in a linux VM. It might work under WSL.

socketcan 虚拟接口设置 / virtual interface setup

# 设置虚拟socketCAN接口
# setup a virtual socketCAN interface
sudo ip link add name vcan0 type vcan
sudo ip link set vcan0 up

构建例子 / building the example

make example

在vcan0接口上运行例子服务器 / run the server on vcan0

./server vcan0
# 服务器会一直跑。用 ctrl+c 推出
# The server will run continuously. Use ctrl+c to exit

在vcan0接口上运行客户端 (打开另一个终端) / run the client on vcan0 (open another shell)

./client vcan0
# 客户端跑完流程后会自动退出
# The client will exit after it has executed its sequence

用candump看看输出

> candump -tz vcan0

也可以用python-udsoncan实现客户端 / You can also use python-udsoncan to implement a client

# 在另外一个终端，安装python依赖性
# In another shell, install the required python packages
pip3 install -r example/requirements.txt

# 然后运行客户端
# then run the client
./example/client.py vcan0
