SAE J1939协议是基于CAN2.0B协议之上的应用层协议，但是SAE J1939协议并不仅仅是个应用层协议，她对物理层，数据链路层，网络层，应用层，故障诊断， 网络层管理层等都做了详细的规定,只不过这其中很多规定都跟CAN2.0B一致。我们这里只介绍J1939的应用层，对软件开发来说已经足够。 对熟悉CAN2.0B协议的小伙伴来说，其实只要掌握下面几个关键点，J1939就瞬间不再神秘。

1、下载微软官方提供的操作Excel的dll，Microsoft.Office.Interop.Excel.dll

首先root用户登陆 sudo -i 一、没有安装wget的先安装wget sudo yum -y install wget 二、下载ss一键安装脚本 ``` mkdir ss_pack #建立文件夹 cd ss_pack #切换到文件夹

1、启动终端 sudo wget http://www.linuxidc.com/files/repo/google-chrome.list -P /etc/apt/sources.list.d/ wget -q -O - https://dl.google.com/linux/linux_signing_key.pub | sudo apt-key add - sudo apt-get update sudo apt-get install google-chrome-stable /usr/bin/google-chrome-stable 2、为chrom安装flash播放器 屏幕右上角，“系统设置”–>“软件和更新”–>“其它软件” 勾选“Canonical合作伙伴” 点击“关闭” 终端输入 sudo apt install adobe-flashplugin

在网上找了很多，没找到这方面的教程，通过Qt官方帮助终于调试成功。Qt有专门的类实现com组件的调用，说明文档上有很多种方式，这里简单说明一种方式。

关于大漠插件，网上看了很多教程，自己走了很多坑，终于调试成功，现在将坑公之于众。 第一步，首先选择调试平台，大漠插件只支持32位编译，如果不选择实例化大漠对象的时候会出现没有注册类的报错，这个坑了我很久，如下图所示，右键程项目->属性
