socketcan的测试例程

使用的是autoware源码中的socketcan程序驱动

• 发送例程

#include <socketcan/socket_can_receiver.hpp>
#include <socketcan/socket_can_sender.hpp>

#include <chrono>
#include <memory>
#include<iostream>
using autoware::drivers::socketcan::SocketCanReceiver;
using autoware::drivers::socketcan::SocketCanSender;

using autoware::drivers::socketcan::CanId;
using autoware::drivers::socketcan::StandardFrame;
using autoware::drivers::socketcan::ExtendedFrame;
using autoware::drivers::socketcan::FrameType;

std::chrono::milliseconds send_timeout_{1LL};
CanId send_id{0x123};
int main(int argc,char*argv[])
{
//shilihua sender can0
SocketCanSender socket_s("can0",send_id);
//fasongshuju
union data{
    char ch[8];
    uint64_t total;
};
union data to_send;
to_send.ch[0] = 0x41;
to_send.ch[1] = 0x42;
to_send.ch[2] = 0x43;
to_send.ch[3] = 0x44;
to_send.ch[4] = 0x45;
to_send.ch[5] = 0x46;
to_send.ch[6] = 0x47;
to_send.ch[7] = 0x48;
//uint64_t send_data = 0x5A'5A'5A'5A'U;

//fasong
socket_s.send(&to_send.total,sizeof(to_send),send_id,send_timeout_);

//xianshifasong
printf("send data : ");
for(int i =0; i <8;++i)
printf(" 0x%x",to_send.ch[i]);
std::cout<<std::endl;

return 0;
}

输出结果：

send data :  0x41 0x42 0x43 0x44 0x45 0x46 0x47 0x48
