Vehicle Control System

This project implements a vehicle control system using D-Bus and C++ on Ubuntu. It provides a DBus interface to control and monitor a vehicle's steering and speed via D-Bus messages.

Prerequisites

Before you can build and run this project, you need to install the necessary dependencies and set up your environment.

Dependencies

Install the necessary C++ and D-Bus development libraries:

sudo apt update
sudo apt install build-essential libdbus-1-dev libdbus-c++-dev

Generating Proxy Classes from XML To generate C++ proxy classes from your DBus XML interface definition, use the dbusxx-xml2cpp tool:

dbusxx-xml2cpp vehicle_control.xml --proxy=vehicle_control_proxy.h

This command generates a header file vehicle_control_proxy.h, which is included in the source files to interact with the DBus interface.

Compilation Compile the project using g++ and the flags provided by pkg-config:

g++ -o vehicle_control main_subscribe.cpp `pkg-config --cflags --libs dbus-c++-1`

This command compiles main_subscribe.cpp, linking against the necessary libraries, and produces an executable named vehicle_control.

Running the Application Run the executable in a terminal:

./vehicle_control

Ensure that the DBus system is properly configured and that your user has the necessary permissions to interact with DBus.

Project Structure vehicle_control.xml: XML file describing the DBus interface. vehicle_control_proxy.h: Generated proxy class from the XML interface. main_subscribe.cpp: Main application source file that sets up the DBus connection and listens for signals.
